PF00792Phosphoinositide 3-kinase C2 (PI3K_C2)Phosphoinositide 3-kinase C2Phosphoinositide 3-kinase region postulated to contain a C2 domain. Outlier of Pfam:PF00168 family.Domain
PF00794PI3-kinase family, ras-binding domain (PI3K_rbd)PI3-kinase family, ras-binding domainCertain 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 These regions show some similarity (although not highly significant similarity) to Ras-binding Pfam:PF00788 domains (unpublished observation).Domain
PF00454Phosphatidylinositol 3- and 4-kinase (PI3_PI4_kinase)Phosphatidylinositol 3- and 4-kinase- Family
