MTMR2

Myotubularin-related protein 2 also known as phosphatidylinositol-3,5-bisphosphate 3-phosphatase or phosphatidylinositol-3-phosphate phosphatase is a protein that in humans is encoded by the MTMR2 gene.

Function
This gene is a member of the myotubularin family and encodes a putative tyrosine phosphatase. The protein also contains a GRAM domain. Mutations in this gene are a cause of Charcot-Marie-Tooth disease type 4B, an autosomal recessive demyelinating neuropathy. Multiple alternatively spliced transcript variants have been found, but the biological validity of some variants has not been determined.

Interactions
MTMR2 has been shown to interact with SBF1.
