| Primary Identifier | IPR035036 | Type | Family |
| Short Name | Grb10 |
| description | The Grb7 (growth factor receptor-bound 7) family includes Grb7, Grb10, and Grb14. These are adapter proteins mediating signal transduction from multiple cell surface receptors to diverse downstream pathways. They are composed of an N-terminal proline-rich domain, a Ras Associating-like (RA) domain, a Pleckstrin Homology (PH) domain, a PIR (phosphorylated insulin receptor interacting region) domain (also known as the family-specific BPS region), and a C-terminal SH2 domain []. Grb10 inhibits insulin receptor kinase activity and mediates insulin-stimulated degradation of the insulin receptor []. It binds to the regulatory kinase loop of the insulin receptor (IR) via its SH2 and BPS domains []. Grb10 is directly phosphorylated by mTORC1 and may participate in a feedback inhibition of the phosphatidylinositol 3-kinase (PI3K) and extracellular signal-regulated, mitogen-activated protein kinase (ERK-MAPK) pathways []. |
