- _6 value "Overexpression of wild-type SHIP2 (WT-SHIP2) inhibited insulin-induced phosphorylation of Akt at both Thr(308) and Ser(473) in Rat1 fibroblasts expressing insulin receptors. The degree of inhibition was less in the cells expressing either a mutant SHIP2 with R47Q change (R/Q-SHIP2) in the SH2 domain, or a mutant SHIP2 with Y987F change (Y/F-SHIP2) in the C-terminal tyrosine phosphorylation site. However, on addition of a myristoylation signal, WT-SHIP2, R/Q-SHIP2, and Y/F-SHIP2 all efficiently inhibited insulin-induced Akt phosphorylation at both residues, whereas a 5'-phosphatase-defective mutant SHIP2 (deltaIP-SHIP2) with the myristoylation signal did not." provenance.
