G proteins couple receptors of extracellular signals to intracellular signaling pathways. The G protein alpha subunit binds guanyl nucleotide and is a weak GTPase. A set of residues that are unique to G-alpha as compared to its ancestor the Arf-like family form a ring of residues centered on the nucleotide binding site [3]. A Ggamma is found fused to an inactive Galpha in the Dictyostelium protein gbqA [3].
Phosphoinositide phospholipase C beta1-4-like EF-hand domain
This entry represents the first EF-hand domain found in 1-phosphatidylinositol 4,5-bisphosphate phosphodiesterase beta-1-4 (PLCB1-4) from human and related proteins. PLC-beta isoforms mediate the production of the second messenger molecules diacylgly ...
This entry represents the first EF-hand domain found in 1-phosphatidylinositol 4,5-bisphosphate phosphodiesterase beta-1-4 (PLCB1-4) from human and related proteins. PLC-beta isoforms mediate the production of the second messenger molecules diacylglycerol (DAG) and inositol 1,4,5-trisphosphate (IP3) to propagate signals for several physiological responses [1-5].
