[5] The protein encoded by this gene belongs to a small class of prenylated protein tyrosine phosphatases (PTPs).

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

This class of PTPs contain a PTP domain and a characteristic C-terminal prenylation motif.

Studies of this class of PTPs in mice demonstrated that they were prenylated proteins in vivo, which suggested their association with cell plasma membrane.
