A	PF00018	SH3 domain (SH3_1)	SH3 domain	SH3 (Src homology 3) domains are often indicative of a protein involved in signal transduction related to cytoskeletal organisation. First described in the Src cytoplasmic tyrosine kinase Swiss:P12931. The structure is a partly opened beta barrel.	Domain
A	PF00169	PH domain (PH)	PH domain	PH stands for pleckstrin homology.	Domain
A	PF00621	RhoGEF domain (RhoGEF)	RhoGEF domain	Guanine nucleotide exchange factor for Rho/Rac/Cdc42-like GTPases Also called Dbl-homologous (DH) domain. It appears that Pfam:PF00169 domains invariably occur C-terminal to RhoGEF/DH domains.	Domain
