Probable phosphatase which regulates axon regeneration after injury by linking the svh-2 and integrin signaling pathways. Not involved in axon regeneration after injury. H2O + O-phospho-L-tyrosyl-[protein] = L-tyrosyl-[protein] + phosphate May interact (via SH2 domain) with receptor svh-2 (when tyrosine-phosphorylated) (PubMed:31109965). May interact (via C-terminus) with integrin pat-3 (PubMed:31109965). Localizes to punctate structures along the axon in motor neurons. Expressed in ventral motor neurons, including ventral and dorsal D-type neurons, and in a subset of cells in the head. Belongs to the PTEN phosphatase protein family.
