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 These regions show some similarity (although not highly significant similarity) to Ras-binding Pfam:PF00788 domains (unpublished observation).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 | |
