PTPs are cell signaling molecules that play regulatory roles in a variety of cellular processes.

PTPs in this class contain a protein tyrosine phosphatase catalytic domain and a characteristic C-terminal prenylation motif.

This PTP has been shown to primarily associate with plasmic and endosomal membrane through its C-terminal prenylation.

Overexpression of this gene in mammalian cells conferred a transformed phenotype, which suggested its role in tumorigenesis.
