4-44 | 2.94e-22 | |||
dimerization/docking (D/D) domain of the Type II alpha Regulatory subunit of cAMP-dependent protein kinase; cAMP-dependent protein kinase (PKA) is a serine/threonine kinase (STK), catalyzing the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. The inactive PKA holoenzyme is a heterotetramer composed of two phosphorylated and active catalytic subunits with a dimer of regulatory (R) subunits. Activation is achieved through the binding of the important second messenger cAMP to the R subunits, which leads to the dissociation of PKA into the R dimer and two active subunits. There are two classes of R subunits, RI and RII; each exists as two isoforms (alpha and beta) from distinct genes. These functionally non-redundant R isoforms allow for specificity in PKA signaling. RII subunits contain a phosphorylation site in their inhibitory site and are both substrates and inhibitors. RIIalpha plays a role in the association and dissociation of PKA with the centrosome during interphase and mitosis, respectively. It is also involved in endosome-to-Golgi and Golgi-to-ER transport. The R subunit contains an N-terminal dimerization/docking (D/D) domain, a linker with an inhibitory sequence, and two c-AMP binding domains. The D/D domain dimerizes to form a four-helix bundle that serves as a docking site for A-kinase-anchoring proteins (AKAPs), which facilitates the localization of PKA to specific sites in the cell. PKA is present ubiquitously in cells and interacts with many different downstream targets. It plays a role in the regulation of diverse processes such as growth, development, memory, metabolism, gene expression, immunity, and lipolysis. : Pssm-ID: 438524 Cd Length: 41 Bit Score: 88.35 E-value: 2.94e-22

The inactive PKA holoenzyme is a heterotetramer composed of two phosphorylated and active catalytic subunits with a dimer of regulatory (R) subunits. Activation is achieved through the binding of the important second messenger cAMP to the R subunits, which leads to the dissociation of PKA into the R dimer and two active subunits. There are two classes of R subunits, RI and RII; each exists as two isoforms (alpha and beta) from distinct genes. These functionally non-redundant R isoforms allow for specificity in PKA signaling. The R subunit contains an N-terminal dimerization/docking (D/D) domain, a linker with an inhibitory sequence (IS), and two c-AMP binding domains. RI and RII subunits are distinguished by their IS; RII subunits contain a phosphorylation site and are both substrates and inhibitors while RI subunits are pseudo-substrates. RI subunits require ATP and Mg ions to form a stable holoenzyme while RII subunits do not. The D/D domain dimerizes to form a four-helix bundle that serves as a docking site for A-kinase-anchoring proteins (AKAPs), which facilitates the localization of PKA to specific sites in the cell. PKA is present ubiquitously in cells and interacts with many different downstream targets. It plays a role in the regulation of diverse processes such as growth, development, memory, metabolism, gene expression, immunity, and lipolysis.

dimerization/docking (D/D) domain of the sperm fibrous sheath proteins, Calcium-Binding tYrosine-phosphorylation Regulated protein and Sperm Protein 17; CABYR and SP17 are naturally located in the human sperm fibrous sheath (FS). CABYR was originally isolated from spermatoza and was thought to be testis-specific, but has recently been observed in lung and brain tumors. It is a polymorphic calcium binding protein that is phosphorylated during capacitation. SP17 plays an important role in the interaction of sperm with the zona pellucida during fertilization. It also promotes cell-cell adhesion. SP17 is found in various human tumors of unrelated histological origin including metastatic squamous cell carcinoma, multiple myeloma, ovarian cancer, and primary nervous system tumors, among others. Both CABYR and SP17 contain an N-terminal dimerization/docking (D/D) domain with similarity to the D/D domain of the R subunit of cAMP-dependent protein kinase (PKA). The D/D domain of the R subunit dimerizes to form a four-helix bundle that serves as a docking site for A-kinase-anchoring proteins (AKAPs), which facilitates the localization of PKA to specific sites in the cell. The D/D domain of CABYR and SP17 have been shown to bind to AKAP3, a protein that is also associated to the FS of mammalian spermatozoa.

dimerization/docking (D/D) domains found in the cAMP-dependent protein kinase regulatory subunit (PRKAR) and the DPY30/SDC1-like family; This hierarchy includes the dimerization/docking (D/D) domains of type I and type II cAMP-dependent protein kinase (PKA) regulatory (R) subunits, DPY30 from animals and its homologs, SDC1 from yeasts, and similar domains. PKA is a serine/threonine kinase (STK), catalyzing the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. The inactive PKA holoenzyme is a heterotetramer composed of two phosphorylated and active catalytic subunits with a dimer of R subunits. Activation is achieved through the binding of the important second messenger cAMP to the R subunits, which leads to the dissociation of PKA into the R dimer and two active subunits. There are two classes of R subunits, RI and RII; each exists as two isoforms (alpha and beta) from distinct genes. These functionally non-redundant R isoforms allow for specificity in PKA signaling. The R subunit contains an N-terminal D/D domain, a linker with an inhibitory sequence (IS), and two c-AMP binding domains. The D/D domain dimerizes to form a four-helix bundle that serves as a docking site for A-kinase-anchoring proteins (AKAPs), which facilitates the localization of PKA to specific sites in the cell. DPY30, also called dumpy-30, was initially discovered in Caenorhabditis elegans as a key player in X chromosome dosage compensation. Human DPY30 plays a dual function in moderately regulating the methyltransferase activity of SET1/COMPASS (COMplex of Proteins ASsociated with Set1) enzymes and contributing to the recruitment of the complex to chromatin. Yeast SDC1 (suppressor of CDC25 protein 1) is the smallest subunit of COMPASS (COMplex of Proteins ASsociated with Set1) and interacts exclusively with Bre2 at the distal end of the catalytic module. It positively regulates the COMPASS catalytic module by stabilizing the non-canonical Bre2 SPRY domain. DPY30/SDC1 contains a C-terminal helical bundle domain that directly interacts with Ash2L (in human)/Bre2 (in yeast) COMPASS through the DPY30-binding motif (DBM). The DPY30/SDC1 helical bundle domain, also called D/D domain, is formed of two alpha-helices that may be analogous to the D/D domain found in regulatory subunit of PKA.

dimerization/docking (D/D) domain found in Saccharomyces cerevisiae cAMP-dependent protein kinase regulatory subunit and similar domains; cAMP-dependent protein kinase (PKA) is a serine/threonine kinase (STK), catalyzing the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. The inactive PKA holoenzyme is a heterotetramer composed of two phosphorylated and active catalytic subunits with a dimer of regulatory (R) subunits. Activation is achieved through the binding of the important second messenger cAMP to the R subunits, which leads to the dissociation of PKA into the R dimer and two active subunits. The R subunit of fungal PKA is encoded by a single gene, which is called by various names in different organisms (for example: Yarrowia lipolytica RKA1, Saccharomyces cerevisiae Bcy1, and Schizosaccharomyces pombe Cgs1). Although most characterized PKA holoenzymes are tetramers, Y. lipolytica PKA has been reported to be a dimer of RKA1 and the catalytic subunit TPK1. RKA1 is essential and promotes hyphal growth. Cgs1 is essential for sexual differentiation of S. pombe; mutants with defective Cgs1 are partially sterile. The R subunit contains an N-terminal dimerization/docking (D/D) domain, a linker with an inhibitory sequence, and two c-AMP binding domains. The D/D domain of metazoan R subunits dimerizes to form a four-helix bundle that serves as a docking site for A-kinase-anchoring proteins (AKAPs). The D/D domain of fungal R subunits may also serve as a dimerization domain, in the case of heterotetrameric PKAs. Fungal PKA plays a major role in controlling cell growth and metabolism in response to nutrients and stress conditions. Pssm-ID: 438519 Cd Length: 45 Bit Score: 40.98 E-value: 2.81e-05
