Overview:

The SH2-containing inositol-5′-phosphatase 2 (SHIP2) belongs to the family of the mammalian inositol polyphosphate 5-phosphatases that catalyze the dephosphorylation of phosphoinositides and inositol phosphates with a phosphate at 5-position of the inositol ring. In addition to the N-terminal SH2 domains and N- and C-terminal proline-rich regions with consensus sites for SH3 domain interactions, SHIP2 also contains an SAM domain in the C-terminus interacting with the EphA2 receptor and with a PI 3-kinase effector protein regulating both Arf and Rho GTPases, ARAP3.
