Chains	Accession	Name	Description	Comments	Source
A	PF22697	SOS1/NGEF-like PH domain (SOS1_NGEF_PH)	SOS1/NGEF-like PH domain	This is a PH domain found in a diverse group of animal proteins such as Ephexin-1, SOS1 from human and related RhoGEFs [1-5].	Domain
A	PF07653	Variant SH3 domain (SH3_2)	Variant 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	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
