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.
Overexpression of this gene in mammalian cells was reported to
inhibit angiotensin-II induced cell calcium mobilization and
promote cell growth. Two alternatively spliced variants exist.
