Predicted to enable protein tyrosine phosphatase activity. Predicted to be involved in peptidyl-tyrosine dephosphorylation involved in inactivation of protein kinase activity and regulation of fat cell differentiation. Predicted to act upstream of or within several processes, including detection of mechanical stimulus involved in sensory perception of sound; hematopoietic progenitor cell differentiation; and vestibular receptor cell morphogenesis. Predicted to be located in stereocilium bundle. Predicted to be part of receptor complex. Human ortholog(s) of this gene implicated in autosomal dominant nonsyndromic deafness 73 and autosomal recessive nonsyndromic deafness 84A. Orthologous to human PTPRQ (protein tyrosine phosphatase receptor type Q). [provided by Alliance of Genome Resources, Apr 2022]
