mu-homology domain (MHD) of Scr homology 3 (SH3)-domain growth factor receptor-bound 2 (GRB2) ...
342-608 0e+00

mu-homology domain (MHD) of Scr homology 3 (SH3)-domain growth factor receptor-bound 2 (GRB2)-like (endophilin) interacting protein 1 (also known as endophilin-3-interacting protein, SGIP1) and similar proteins; This family corresponds to the MHD found in mammalian neuronal-specific transcript SGIP1 and similar proteins. Unlike other members in this family, SGIP1 does not contain EFC/F-BAR domain, but does have a proline-rich domain (PRD) and a C-terminal MHD. It is an endophilin-interacting protein that plays an obligatory role in the regulation of energy homeostasis, and is also involved in clathrin-mediated endocytosis by interacting with phospholipids and eps15.

341-606 1.46e-95

Muniscin C-terminal mu homology domain; The muniscins are a family of endocytic adaptors that is conserved from yeast to humans.This C-terminal domain is structurally similar to mu homology domains, and is the region of the muniscin proteins involved in the interactions with the endocytic adaptor-scaffold proteins Ede1-eps15. This interaction influences muniscin localization. The muniscins provide a combined adaptor-membrane-tubulation activity that is important for regulating endocytosis.

342-608 1.39e-176

Mu-homology domain (MHD) of endocytic adaptor protein (AP), Syp1; This family corresponds to the MHD found in the metazoan counterparts of yeast Syp1, which includes two ubiquitously expressed membrane-sculpting F-BAR domain-containing Fer/Cip4 homology domain-only proteins 1 and 2 (FCH domain only 1 and 2, or FCHo1/FCHo2), neuronal-specific SH3-containing GRB2-like protein 3-interacting protein 1 (SGIP1), and related uncharacterized proteins. FCHo1/FCHo2 represent key initial proteins ultimately controlling cellular nutrient uptake, receptor regulation, and synaptic vesicle retrieval. They are required for plasma membrane clathrin-coated vesicle (CCV) budding and marked sites of CCV formation. They bind specifically to the plasma membrane and recruit the scaffold proteins eps15 and intersectin, which subsequently engage the adaptor complex AP2 and clathrin, leading to coated vesicle formation. Both FCHo1/FCHo2 contain an N-terminal EFC/F-BAR domain that induces membrane tabulation, a proline-rich domain (PRD) in the middle region, and a C-terminal MHD responsible for the binding of eps15 and intersectin. Another mammalian neuronal-specific protein, neuronal-specific transcript Scr homology 3 (SH3)-domain growth factor receptor-bound 2 (GRB2)-like (endophilin) interacting protein 1 [SGIP1] does not contain EFC/F-BAR domain, but does have a PRD and a C-terminal MHD and has been classified into this family as well. SGIP1 is an endophilin-interacting protein that plays an obligatory role in the regulation of energy homeostasis. It is also involved in clathrin-mediated endocytosis by interacting with phospholipids and eps15.

mu-homology domain (MHD) of F-BAR domain-containing Fer/Cip4 homology domain-only protein 2 (FCH domain only 2 or FCHo2) and similar proteins; This family corresponds to the MHD found in the ubiquitously expressed mammalian membrane-sculpting FCHo2 and similar proteins. FCHo2 represents a key initial protein that ultimately controls cellular nutrient uptake, receptor regulation, and synaptic vesicle retrieval.

It binds specifically to the plasma membrane and recruits the scaffold proteins eps15 and intersectin, which subsequently engages the adaptor complex AP2 and clathrin, leading to coated vesicle formation. FCHo2 contains an N-terminal EFC/F-BAR domain, a proline-rich domain (PRD) in the middle region, and a C-terminal MHD. The crescent-shaped EFC/F-BAR domain can form an antiparallel dimer structure that binds PtdIns(4,5)P2-enriched membranes and can polymerize into rings to generate membrane tubules. The MHD is structurally related to the cargo-binding mu2 subunit of adaptor complex 2 (AP-2) and is responsible for the binding of eps15 and intersectin.

It binds specifically to the plasma membrane and recruits the scaffold proteins eps15 and intersectin, which subsequently engage the adaptor complex AP2 and clathrin, leading to coated vesicle formation. FCHo1 contains an N-terminal EFC/F-BAR domain, a proline-rich domain (PRD) in the middle region, and a C-terminal MHD. The crescent-shaped EFC/F-BAR domain can form an antiparallel dimer structure that binds PtdIns(4,5)P2-enriched membranes and can polymerize into rings to generate membrane tubules. The MHD is structurally related to the cargo-binding mu2 subunit of adaptor complex 2 (AP-2) and is responsible for the binding of eps15 and intersectin. Unlike other F-BAR domain containing proteins, FCHo1 has neither the Src homology 3 (SH3) domain nor any other known domain for interaction with dynamin and actin cytoskeleton. However, it can periodically accumulate at the budding site of clathrin. FCHo1 may utilize a unique action mode for vesicle formation as compared with other F-BAR proteins.

Muniscin C-terminal mu homology domain; The muniscins are a family of endocytic adaptors that is conserved from yeast to humans.This C-terminal domain is structurally similar to mu homology domains, and is the region of the muniscin proteins involved in the interactions with the endocytic adaptor-scaffold proteins Ede1-eps15. This interaction influences muniscin localization. The muniscins provide a combined adaptor-membrane-tubulation activity that is important for regulating endocytosis.

342-608 2.81e-53

Mu-homology domain (MHD) of muniscins adaptor proteins (AP) and similar proteins; This family corresponds to the MHD found in muniscins, a novel family of endocytic adaptor proteins. The term, muniscins, has been assigned to name the MHD of proteins with both EFC/F-BAR domain and MHD. These two domains are responsible for the membrane-tubulation activity associated with transmembrane cargo proteins. Members in this family include an endocytic adaptor Syp1, the mammalian FCH domain only proteins (FCHo1/2), SH3-containing GRB2-like protein 3-interacting protein 1 (SGIP1), and related uncharacterized proteins. Syp1 is a poorly characterized yeast protein with multiple biological functions. Syp1 contains an N-terminal EFC/F-BAR domain that induces membrane tabulation, a proline-rich domain (PRD) in the middle region, and a C-terminal MHD that can directly binds to the endocytic adaptor/scaffold protein Ede1 or a transmembrane stress sensor cargo protein Mid2. Thus, Syp1 represents a novel type of endocytic adaptor protein that participates in endocytosis, promotes vesicle tabulation, and contributes to cell polarity and stress response. Syp1 shares the same domain architecture with its two ubiquitously expressed mammalian counterparts, the membrane-sculpting F-BAR domain-containing Fer/Cip4 homology domain-only proteins 1 and 2 (FCHo1/2). FCHo1/2 represent key initial proteins ultimately controlling cellular nutrient uptake, receptor regulation, and synaptic vesicle retrieval. They are required for plasma membrane clathrin-coated vesicle (CCV) budding and marked sites of CCV formation. They bind specifically to the plasma membrane and recruit the scaffold proteins eps15 and intersectin, which subsequently engage the adaptor complex AP2 and clathrin, leading to coated vesicle formation. Another mammalian neuronal-specific protein, neuronal-specific transcript Scr homology 3 (SH3)-domain growth factor receptor-bound 2 (GRB2)-like (endophilin) interacting protein 1 [SGIP1] does not contain EFC/F-BAR domain, but does have a PRD and a C-terminal MHD and has been classified into this family as well. SGIP1 is an endophilin-interacting protein that plays an obligatory role in the regulation of energy homeostasis. It is also involved in clathrin-mediated endocytosis by interacting with phospholipids and eps15.

345-572 1.09e-17

mu-homology domain (MHD) of adaptor protein (AP), Syp1, and related proteins; This family corresponds to the MHD found in a novel endocytic adaptor Syp1 and related proteins. Syp1 is a poorly characterized yeast protein with multiple biological functions. It was originally identified as a suppressor of a yeast profiling deletion and later as a suppressor of arf3delta (Arf3 is the yeast homologue of Arf6, a mammalian regulator of endocytosis). Syp1 can bind to septins and physically link with cell polarity factors. It also directly binds to the endocytic adaptor/scaffold protein Ede1, and plays a role in endocytosis. Further studies show that Syp1 is itself an endocytic adaptor protein contributing to stress responses. Its mu-homology domain at the C-terminus binds to the cargo protein Mid2, a transmembrane stress sensor protein, and mediates Mid2 internalization. In addition, Syp1 contains an EFC/F-BAR domain which can induce membrane tabulation.

Atg29 N-terminal domain; This is the N-terminal domain found in fungal Atg proteins such as Atg29. In yeast, the induction of autophagy begins at a single perivacuolar site that is proximal to the vacuole, called the phagophore assembly site (PAS). Atg17-Atg29-Atg31 complex (Atg1 complex) formation is a prerequisite for PAS assembly. Functional analysis indicate that the N-terminal half Atg29 can bind Atg31.
