PF16454 | Phosphatidylinositol 3-kinase regulatory subunit P85 inter-SH2 domain (PI3K_P85_iSH2) | Phosphatidylinositol 3-kinase regulatory subunit P85 inter-SH2 domain | This domain is found between the two SH2 domains in phosphatidylinositol 3-kinase regulatory subunit P85. It forms a complex with the adaptor-binding domain of phosphatidylinositol 4,5-bisphosphate 3-kinase catalytic subunit alpha [1]. | 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 These regions show some similarity (although not highly significant similarity) to Ras-binding Pfam:PF00788 domains (unpublished observation).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 | |
