cAMP-dependent protein kinase type I-beta regulatory subunit [Homo sapiens]
cyclic nucleotide-binding domain-containing protein( domain architecture ID 10186673)
cyclic nucleotide-binding domain-containing protein binds cyclic nucleotides (cAMP or cGMP) where binding of the effector leads to conformational changes; may be involved in regulating transcription, be present in cAMP- and cGMP-dependent protein kinases (cAPK and cGPK), or be part of vertebrate cyclic nucleotide-gated ion-channels.

dimerization/docking (D/D) domain of the Type I beta 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. RI subunits are pseudo-substrates as they do not contain a phosphorylation site in their inhibitory site unlike RII subunits. RIbeta is expressed highly in the brain and is associated with hippocampal function. 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: 438523 Cd Length: 54 Bit Score: 114.65 E-value: 5.70e-32

15-57 | 1.42e-06 | ||||
dimerization/docking (D/D) domain found in the testis-specific expressed protein 55 (TEX55)-like family; The TEX55-like family includes TEX55, F-box/LRR-repeat protein 13 (FBXL13), adenylate kinase isoenzymes AK5 and AK8, as well as uncharacterized EF-hand calcium-binding domain-containing protein 10 (EFCAB10), and protein VEST-1. TEX55, also called testis-specific conserved cAMP-dependent type II PK-anchoring protein (TSCPA), is a putative A-kinase anchoring protein (AKAP) that is dispensable for male fertility. FBXL13, also called F-box and leucine-rich repeat protein 13, or dynein regulatory complex subunit 6 (DRC6), is a component of the nexin-dynein regulatory complex (N-DRC), a key regulator of ciliary/flagellar motility which maintains the alignment and integrity of the distal axoneme and regulates microtubule sliding in motile axonemes. It may also function as a substrate-recognition component of an SCF (SKP1-CUL1-F-box protein)-type E3 ubiquitin ligase complex. AK5 and AK8 act as nucleoside monophosphate (NMP) kinases that catalyze the reversible transfer of the terminal phosphate group between nucleoside triphosphates and monophosphates. Members of this family contain a conserved helical bundle domain that shows high sequence similarity to the dimerization/docking (D/D) domains of regulatory subunit of cAMP-dependent protein kinase (PKA) and protein DPY-30/SDC1.

dimerization/docking (D/D) domain found in Trypanosoma brucei adenylate kinase (AK) and similar proteins; AK (EC 2.7.4.3), also called ATP-AMP transphosphorylase, ATP:AMP phosphotransferase, or adenylate monophosphate kinase, catalyzes the reversible transfer of the terminal phosphate group between ATP and AMP. It plays an important role in cellular energy homeostasis and in adenine nucleotide metabolism.
