Structural basis for interdomain communication in SHIP2 providing high phosphatase activity

open access: yeseLife, 2017
SH2-containing-inositol-5-phosphatases (SHIPs) dephosphorylate the 5-phosphate of phosphatidylinositol-3,4,5-trisphosphate (PI(3,4,5)P3) and play important roles in regulating the PI3K/Akt pathway in physiology and disease.
