Myotubularin-related protein 2 is a protein that in humans is encoded by the MTMR2 gene.[1][2][3]

Function[edit]

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.[3]

Interactions[edit]

MTMR2 has been shown to interact with SBF1.[4]
