Description

General description

Protein tyrosine phosphatase non-receptor type 2 (PTPN2), also known as T cell protein tyrosine phosphatase (TCPTP), is an intracellular nonreceptor tyrosine-specific phosphatase that is expressed ubiquitously at various stages of mammalian development. PTPN2 exists as two alternatively spliced variants, PTPN2 isoform 1 (p48TC, 48 kDa) that is targeted to the endoplasmic reticulum by a hydrophobic C-terminal region and a shorter PTPN2 isoform 2 (p45TC, 45 kDa) that is targeted to the nucleus.

Immunogen

synthetic peptide corresponding to a sequence located near the C-terminus of human PTPN2, conjugated to KLH. The corresponding sequence is identical in human PTPN2 isoform 2 and highly conserved (single amino acid substitution) in mouse PTPN2.

Application

Anti-PTPN2 antibody produced in rabbit has been used in:

• immunoblotting
• immunoprecipitation
• immunostaining

Biochem/physiol Actions

PTPN2 acts on several cytoplasmic substrates including epidermal growth factor receptor (EGFR), insulin receptor (InsR), Shc, janus kinases (JAKs), and the nuclear substrate signal transducer and activator of transcription 1 (STAT1). PTPN2 has been associated with type 1 diabetes.

Protein tyrosine phosphatase non-receptor type 2 (PTPN2) is a tyrosine phosphatase that negatively regulates tyrosine kinase and JAK/STAT signaling pathways. PTPN2 inhibits oncogenic JAK1 and thereby functions as a tumor suppressor in T-cell malignancies. Genetic alterations in PTPN2 have been associated with the risk of Crohn′s disease and ulcerative colitis .
