Paul A. Welling, in Seldin and Giebisch's The Kidney (Fifth Edition), 2013 AKAP. These scaffolds hold PKA close to its partners in the signaling cascade, further tuning its function. The cyclic AMP-dependent protein kinase A is compartmentalized through its association with A-kinase anchoring proteins (AKAPs . The defining feature of AKAPs is their ability to bind Thus AKAPs and AKAP associated proteins appear to be key molecules in the biochemical machinery regulating the functions of flagella and cilia. motif is found in the DPY-30 domain, which suggests this domain may also play a localization role. complex orchestrated by a scaffold protein; the most studied family of scaffold proteins coordinating cAMP signalling is the A-kinase anchoring protein (AKAP) family, outlined in the next paragraph. A-kinase anchoring proteins (AKAPs) spatially constrain phosphorylation by cAMP-dependent protein kinases (PKA). Rapid, voltage-dependent potentiation of skeletal muscle L-type calcium channels requires phosphorylation by cAMP-dependent protein kinase (PKA) anchored via an A kinase anchoring protein (AKAP). Current efforts in the laboratory are to understand how Ca²⁺/CaM binds to and modulates the activity of other channels such as ion channels. In the damaged heart, loss of function is mainly due to cardiomyocyte death and associated cardiac remodeling and fibrosis. Another anchoring protein, AKAP 95, changes its intracellular location during the cell cycle. Compartmentalization of cyclic AMP-dependent protein kinase (PKA) is achieved through association with A-kinase anchoring proteins (AKAPs). AKAPs also bind additional signaling proteins (for example other protein kinases, protein phosphatases, phopshodiesterases, adenylyl cyclases and small G proteins). Activation of β 2-adrenergic receptors (AR) on CD4 + T lymphocytes has been shown to inhibit Th1-cytokine production and cell proliferation. cellular component movement [ IBA] The function of a multi-domain pro-tein is the sum of the functions of all of its domains, and each individual domain can reveal a new functionality for the pro-tein.
