PTEN missense mutation that results in the substitution of glycine at position 129 with glutamic acid affects the conserved H-C-K/R-A-G-K-G-R sequence (corresponding to HCXXGXXR motif of protein tyrosine phosphatases) in the catalytic cleft of the PTEN phosphatase domain. PTEN G129E (Gly129Glu) mutant shows markedly decreased phosphoinositide phosphatase activity (Han et al. 2000).
