T Cell Protein Tyrosine Phosphatase

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.
