PTPs are known to be signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitotic cycle, and oncogenic transformation.

This PTP contains a PEST motif, which often serves as a protein-protein interaction domain, and may be related to protein intracellular half-life.

This gene was found to be expressed in brain, colon tissues, and several different tumor-derived cell lines.

The biological function of this PTP has not yet been determined.
