A subtype of non-receptor protein tyrosine phosphatase that is closely-related to PROTEIN TYROSINE PHOSPHATASE, NON-RECEPTOR TYPE 1. Alternative splicing of the mRNA for this phosphatase results in the production at two gene products, one of which includes a C-terminal nuclear localization domain that may be involved in the transport of the protein to the CELL NUCLEUS. Although initially referred to as T-cell protein tyrosine phosphatase the expression of this subtype occurs widely.
