Myotubularin-related protein 2 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. 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.
