The protein encoded by this gene is a member of the protein tyrosine phosphatase (PTP) family. PTPs are known to be signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitotic cycle, and oncogenic transformation. Two alternatively spliced transcript variants of this gene have been reported, one of which encodes a receptor-type PTP that possesses a short extracellular domain, a single transmembrane region, and two tandem intracytoplasmic catalytic domains; Another one encodes a PTP that contains a distinct hydrophilic N-terminus, and thus represents a nonreceptor-type isoform of this PTP. Studies of the similar gene in mice suggested the regulatory roles of this PTP in RAS related signal transduction pathways, cytokines induced SATA signaling, as well as the activation of voltage-gated K+ channels.

PTPRE (AAH50062, 511 a.a. ~ 600 a.a) partial recombinant protein with GST tag. MW of the GST tag alone is 26 KDa.
PTPRE (Protein tyrosine phosphatase, receptor type, E) is associated with various signalling pathways including down regulation of insulin receptor signalling and Janus kinase (Jak)-STAT inhibition signalling pathway. It also plays an important role in the regulation of ERK1/2 pathway by emerging as a phosphatase through its catalytic activity. Study shows that it may play an accessory role in tumour development.

This report describes the identification and characterization of a novel cytoplasmic isoform of human protein tyrosine phosphatase epsilon (PTPepsilon). The novel isoform, denoted cyt-PTPepsilonPD1, displays only the N-terminal catalytic, active phosphatase domain 1 (PD1) which is common in all known

The expression of protein tyrosine phosphatase epsilon (PTPepsilon) was studied in human tissues and blood cells. High mRNA expression was observed in peripheral blood leucocytes, particularly in monocytes and granulocytes which revealed at least four distinct transcripts. In lymphocytes, PTPepsilon
