FunFam 2500: Pi3K21B, isoform B

Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

There are 4 GO terms relating to "molecular function"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Kinase binding GO:0019900
Interacting selectively and non-covalently with a kinase, any enzyme that catalyzes the transfer of a phosphate group.
3 M9PAY7 (/IPI) O18683 (/IPI) Q7KTZ2 (/IPI)
Phosphatidylinositol 3-kinase regulator activity GO:0035014
Modulates the activity of any of the phosphatidylinositol 3-kinases (PI3Ks). Regulatory subunits can link a PI3K catalytic subunit to upstream signaling events and help position the catalytic subunits close to their lipid substrates.
3 M9PAY7 (/ISS) O18683 (/ISS) Q7KTZ2 (/ISS)
Phosphatidylinositol 3-kinase regulator activity GO:0035014
Modulates the activity of any of the phosphatidylinositol 3-kinases (PI3Ks). Regulatory subunits can link a PI3K catalytic subunit to upstream signaling events and help position the catalytic subunits close to their lipid substrates.
1 O18683 (/IPI)
Insulin receptor substrate binding GO:0043560
Interacting selectively and non-covalently with any of the insulin receptor substrate (IRS) proteins, adaptor proteins that bind to the transphosphorylated insulin and insulin-like growth factor receptors, are themselves phosphorylated and in turn recruit SH2 domain-containing signaling molecules to form a productive signaling complex.

GO Term Annotations Evidence
Phosphatidylinositol 3-kinase complex, class IA GO:0005943
A class I phosphatidylinositol 3-kinase complex that possesses 1-phosphatidylinositol-4-phosphate 3-kinase activity; comprises a catalytic class IA phosphoinositide 3-kinase (PI3K) subunit and an associated SH2 domain-containing regulatory subunit that is a member of a family of related proteins often called p85 proteins. Through the interaction with the SH2-containing adaptor subunits, Class IA PI3K catalytic subunits are linked to tyrosine kinase signaling pathways.
