| B [auth C] | PF00071 | Ras family (Ras) | Ras family | Includes sub-families Ras, Rab, Rac, Ral, Ran, Rap Ypt1 and more. Shares P-loop motif with GTP_EFTU, arf and myosin_head. See Pfam:PF00009 Pfam:PF00025, Pfam:PF00063. As regards Rab GTPases, these are important regulators of vesicle formation, motili ... | Domain |
| PF00792 | Phosphoinositide 3-kinase C2 (PI3K_C2) | Phosphoinositide 3-kinase C2 | Phosphoinositide 3-kinase region postulated to contain a C2 domain. Outlier of Pfam:PF00168 family. | Domain | |
| 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 These regions show some similarity (although not highly significant similarity) to Ras-binding Pfam:PF00788 domains (unpublished observation).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 | |
| PF00454 | Phosphatidylinositol 3- and 4-kinase (PI3_PI4_kinase) | Phosphatidylinositol 3- and 4-kinase | - | Family |
