Chains	Accession	Name	Description	Comments	Source
A	PF00787	PX domain (PX)	PX domain	PX domains bind to phosphoinositides.	Domain
A	PF00794	PI3-kinase family, ras-binding domain (PI3K_rbd)	PI3-kinase family, ras-binding domain	Certain members of the PI3K family possess Ras-binding domains in their N-termini. These regions show some similarity (although not highly significant similarity) to Ras-binding Pfam:PF00788 domains (unpublished observation).	Domain
A	PF00454	Phosphatidylinositol 3- and 4-kinase (PI3_PI4_kinase)	Phosphatidylinositol 3- and 4-kinase	-	Family
