Myotubularin Related Protein 11 (MTMR11)

Myotubularin-related protein 11 is a member of the myotubularin related family of proteins. Members of this family contain the consensus sequence for the active site of protein tyrosine phosphatases. Alternatively spliced variants have been described but their biological validity has not been determined.The myotubularins are a large family of lipid phosphatases with specificity towards PtdIns3P and PtdIns(3,5)P2. Each of the 14 family members bears a signature phosphatase domain, which is inactive in six cases due to amino acid changes at the catalytic site. Fragmentary data have indicated heteromeric interactions between myotubularins, which have hitherto paired an active family member with an inactive one.
