Is predicted to encode a protein with the following domains: C2 domain of PTEN tumour-suppressor protein; PH-like domain superfamily; Protein-tyrosine phosphatase-like; Phosphotyrosine-binding domain; Tensin phosphatase, C2 domain; PTB/PI domain; SH2 domain superfamily; SH2 domain; and Tensin/EPS8 phosphotyrosine-binding domain. Is an ortholog of C. elegans tns-1. In C. elegans, tns-1 is involved in positive regulation of axon regeneration.
