Protein Family Annotation Pfam Database Homepage

Chains Pfam Accession Pfam Identifier Pfam Description Type Source
B PF00168 C2 C2 domain Domain PFAM PF00168
B PF00388 PI-PLC-X Phosphatidylinositol-specific phospholipase C, X domain Family
B PF09279 EF-hand_like Phosphoinositide-specific phospholipase C, efhand-like Domain Members of this family are predominantly found in phosphoinositide-specific phospholipase C. They adopt a structure consisting of a core of four alpha helices, in an EF like fold, and are required for functioning of the enzyme [1]. PFAM PF09279
E PF08703 PLC-beta_C PLC-beta C terminal Domain This domain corresponds to the alpha helical C terminal domain of phospholipase C beta. PFAM PF08703
A PF00503 G-alpha G-protein alpha subunit Domain 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]. PFAM PF00503
B PF00387 PI-PLC-Y Phosphatidylinositol-specific phospholipase C, Y domain Family
