Transmembrane channel-like protein 2 is a protein that in humans is encoded by the TMC2 gene.

This gene is considered a member of a gene family predicted to encode transmembrane proteins. The specific function of this gene is unknown; however, expression in the inner ear suggests that it may be crucial for normal auditory function. Mutations in this gene may underlie hereditary disorders of balance and hearing. [provided by RefSeq, Jul 2008].
Function: May be required for the normal function of cochlear hair cells.
