SH2_Cbl-b_TKB cd09920
Src homology 2 (SH2) domain found in the Cbl-b TKB domain; SH2 found in the Cbl-b TKB domain. ...
225-321 7.30e-58

Src homology 2 (SH2) domain found in the Cbl-b TKB domain; SH2 found in the Cbl-b TKB domain. The Cbl (for Casitas B-lineage lymphoma) family of E3 ubiquitin ligases contains three members Cbl, Cbl-b and Cbl-c. The founding member Cbl was discovered first as the oncogenic protein v-Cbl, a Gag-fusion transforming protein of Cas NS-1 retrovirus, which causes pre- and pro-B lymphomas in mice. The N-terminus of the Cbl proteins is composed of a tyrosine kinase-binding (TKB) domain, also called phosphotyrosine binding (PTB) domain, a short linker region and the RING-type zinc finger. In addition, Cbl and Cbl-b contain a leucine zipper motif and a proline-rich domain in the C-terminus. The TKB domain consists of a four-helix bundle (4H), a calcium-binding EF hand and a divergent SH2 domain. Cbl-b plays a role in early hematopoietic development and is a negative regulator of T-cell receptor, B-cell receptor and high affinity immunoglobulin epsilon receptor signal transduction pathways. It also negatively regulates insulin-like growth factor 1 signaling during muscle atrophy caused by unloading and is involved in EGFR ubiquitination and internalization. Diseases associated with defects in Cbl-b include: multiple sclerosis, autoimmune diseases, including type 1 diabetes, and a craniofacial phenotype. In general SH2 domains are involved in signal transduction. They typically bind pTyr-containing ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites.

323-355 6.15e-09

RING finger (Really Interesting New Gene) domain and U-box domain superfamily; The RING finger is a specialized type of Zn-finger of 40 to 60 residues that binds two atoms of zinc. It is defined by the "cross-brace" motif that chelates zinc atoms by eight amino acid residues, typically Cys or His, arranged in a characteristic spacing. Canonical RING motifs have been categorized into two major subclasses, RING-HC (C3HC4-type) and RING-H2 (C3H2C3-type), according to their Cys/His content. There are also many variants of RING fingers: some have different Cys/His patterns while some lack a single Cys or His residue at typical Zn ligand positions (the fourth or eighth zinc ligand is prevalently exchanged for an Asp, which can indeed chelate Zn in a RING finger as well). C4C4-, C3HC3D-, C2H2C4-, and C3HC5-type RING fingers are closely related to RING-HC fingers. In contrast, C4HC3- (RING-CH alias RINGv), C3H3C2-, C3H2C2D-, C3DHC3-, and C4HC2H-type RING fingers are more closely related to RING-H2 fingers. However, not all RING finger-containing proteins display regular RING finger features, and the RING finger family has turned out to be multifarious. The degenerate RING fingers of the Siz/PIAS RING (SP-RING) family proteins and sporulation protein RMD5, are characterized by lacking the second, fifth, and sixth Zn2+ ion-coordinating residues. They bind only one Zn2+ ion. On the other hand, the RING fingers of the human APC11 and RBX1 proteins can bind a third Zn atom since they harbor four additional Zn ligands. U-box is a modified form of the RING finger domain that lacks metal chelating Cys and His residues. It resembles the cross-brace RING structure consisting of three beta-sheets and a single alpha-helix, which would be stabilized by salt bridges instead of chelated metal ions. U-box proteins are widely distributed among eukaryotic organisms and show a higher prevalence in plants than in other organisms. RING finger/U-box-containing proteins are a group of diverse proteins with a variety of cellular functions, including oncogenesis, development, viral replication, signal transduction, the cell cycle and apoptosis. Many of them are ubiquitin-protein ligases (E3s) that serve as scaffolds for binding to ubiquitin-conjugating enzymes (E2s, also referred to as ubiquitin carrier proteins or UBCs) in close proximity to substrate proteins, which enable efficient transfer of ubiquitin from E2 to the substrates.

323-355 6.15e-09

RING finger, HC subclass, found in E3 ubiquitin-protein ligase Cbl-c and similar proteins; Cbl-c, also known as RING finger protein 57 (RNF57), SH3-binding protein Cbl-3, SH3-binding protein Cbl-c, or signal transduction protein Cbl-c, is an E3 ubiquitin-protein ligase expressed exclusively in epithelial cells. It contains a tyrosine-kinase-binding domain (TKB, also known as the phosphotyrosine binding PTB domain, composed of a four helix-bundle, a Ca2+ binding EF-hand and a highly variant SH2 domain), a C3HC4-type RING-HC finger, and a short proline-rich region, but lacks the ubiquitin-associated (UBA) leucine zipper motif that are present in Cbl and Cbl-b. Cbl-c acts as a regulator of epidermal growth factor receptor (EGFR)-mediated signal transduction. It also suppresses v-Src-induced transformation through ubiquitin-dependent protein degradation. Moreover, Cbl-c ubiquitinates and downregulates RETMEN2A and implicates Enigma (PDLIM7) as a positive regulator of RETMEN2A by blocking Cbl-mediated ubiquitination and degradation. The ubiquitin ligase activity of Cbl-c is increased via the interaction of its RING-HC finger domain with a LIM domain of the paxillin homolog, hydrogen peroxide induced construct 5 (Hic-5).

The N-terminal domain is evolutionarily conserved, and is known to bind to phosphorylated tyrosine residues. The so called N-terminal domain is actually 3 structural domains, of which this is the C-terminal SH2 domain.

RING finger, HC subclass, found in E3 ubiquitin-protein ligase Cbl-c and similar proteins; Cbl-c, also known as RING finger protein 57 (RNF57), SH3-binding protein Cbl-3, SH3-binding protein Cbl-c, or signal transduction protein Cbl-c, is an E3 ubiquitin-protein ligase expressed exclusively in epithelial cells. It contains a tyrosine-kinase-binding domain (TKB, also known as the phosphotyrosine binding PTB domain, composed of a four helix-bundle, a Ca2+ binding EF-hand and a highly variant SH2 domain), a C3HC4-type RING-HC finger, and a short proline-rich region, but lacks the ubiquitin-associated (UBA) leucine zipper motif that are present in Cbl and Cbl-b. Cbl-c acts as a regulator of epidermal growth factor receptor (EGFR)-mediated signal transduction. It also suppresses v-Src-induced transformation through ubiquitin-dependent protein degradation. Moreover, Cbl-c ubiquitinates and downregulates RETMEN2A and implicates Enigma (PDLIM7) as a positive regulator of RETMEN2A by blocking Cbl-mediated ubiquitination and degradation. The ubiquitin ligase activity of Cbl-c is increased via the interaction of its RING-HC finger domain with a LIM domain of the paxillin homolog, hydrogen peroxide induced construct 5 (Hic-5).

RING finger, HC subclass, found in E3 ubiquitin-protein ligase Cbl-b and similar proteins; Cbl-b, also known as Casitas B-lineage lymphoma proto-oncogene b, RING finger protein 56 (RNF56), SH3-binding protein Cbl-b, or signal transduction protein Cbl-b, has been identified as a regulator of antigen-specific, T cell-intrinsic, peripheral immune tolerance, a state also known as clonal anergy. It may inhibit activation of the p85 subunit of phosphoinositide 3-kinase (PI3K), protein kinase C-theta (PKC-theta), and phospholipase C-gamma1 (PLC-gamma1) and negatively regulates T-cell receptor-induced transcription factor nuclear factor kappaB (NF-kappaB) activation. In addition, Cbl-b may target multiple signaling molecules involved in transforming growth factor (TGF)-beta-mediated transactivation pathways. Cbl-b contains a tyrosine-kinase-binding domain (TKB, also known as the phosphotyrosine binding PTB domain, is composed of a four helix-bundle, a Ca2+ binding EF-hand and a highly variant SH2 domain), a proline rich domain, a nuclear localization signal, a C3HC4-type RING-HC finger and an ubiquitin-associated (UBA) domain.

RING finger, HC subclass, found in E3 ubiquitin-protein ligase Cbl and similar proteins; Cbl, also known as Casitas B-lineage lymphoma proto-oncogene, proto-oncogene c-Cbl, RING finger protein 55 (RNF55), or signal transduction protein Cbl, is a multi-domain protein that acts as a key negative regulator of various receptor and non-receptor tyrosine kinase signaling. It contains a tyrosine kinase-binding domain (TKB, also known as the phosphotyrosine binding PTB domain, composed of a four helix-bundle, a Ca2+ binding EF-hand and a highly variant SH2 domain), a proline-rich domain, a C3HC4-type RING-HC finger, and an ubiquitin-associated (UBA) domain. TKB is responsible for the interactions with many tyrosine kinases, such as the colony-stimulating factor-1 (CSF-1) receptor, Syk/ZAP-70, and Src-family of protein tyrosine kinases. The proline-rich domain can recruit proteins with a SH3 domain. Moreover, Cbl functions as an E3 ubiquitin ligase that can bind ubiquitin-conjugating enzymes (E2s) through the RING-HC finger.

Src homology 2 (SH2) domain; In general, SH2 domains are involved in signal transduction; they bind pTyr-containing polypeptide ligands via two surface pockets, a pTyr and hydrophobic binding pocket, allowing proteins with SH2 domains to localize to tyrosine phosphorylated sites. They are present in a wide array of proteins including: adaptor proteins (Nck1, Crk, Grb2), scaffolds (Slp76, Shc, Dapp1), kinases (Src, Syk, Fps, Tec), phosphatases (Shp-1, Shp-2), transcription factors (STAT1), Ras signaling molecules (Ras-Gap), ubiquitination factors (c-Cbl), cytoskeleton regulators (Tensin), signal regulators (SAP), and phospholipid second messengers (PLCgamma), amongst others.
