Anti-PTPN2 antibody produced in rabbit

NA.44

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.

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.

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

• immunoblotting
• immunoprecipitation
• immunostaining

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 .
