SHP-1 (PTPN6), GST-Tag (1-577) Recombinant

Products from BPS Bioscience require a minimum order value above 400€

Encompassing Amino Acids: 1-577

Applications: Useful for the study of enzyme kinetics and regulation, to dephosphorylate target substrates and for screening inhibitors.

Assay Conditions: 50 mM HEPES, pH 7.4, 2 mM EDTA, 3 mM DTT, 100 mM NaCl, 50 mM pNPP.

Background: PTPN6 gene is preferentially expressed in a variety of hematopoietic cells, and is an early response gene in lymphokine stimulated cells. The noncatalytic N-terminus of this PTP can interact with MAP kinases and negatively regulates ERK2 and p38 MAP-kinases activity. The PTPN6 was shown to be involved in the regulation of T cell antigen receptor (TCR) signaling, which was thought to function through dephosphorylating the molecules related to MAP kinase pathway.

Description: Protein tyrosine phosphatase SHP-1, also known as PTPN6 (GenBank accession number NM_080549), full length, with N-terminal GST-tag, MW=95 kDa, expressed in an E. coli expression system.
