Chains	Accession	Name	Description	Comments	Source
A, B	PF09279	Phosphoinositide-specific phospholipase C, efhand-like (EF-hand_like)	Phosphoinositide-specific phospholipase C, efhand-like	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].	Domain
