Gene Information

human ... PTPN6(5777)

General description

Protein tyrosine phosphatase, full length, (Gene bank accession number NM_080549) with N-terminal GST tag, MW = 95 kDa, expressed in an E. coli expression system.
The Src homology region 2 domain-containing phosphatase-1 (SHP1)/protein tyrosine phosphatase, non-receptor type 6 (PTPN6) is a 68 kDa protein present in the cytoplasm. It is mapped to human chromosome 12p13.

Application

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

Biochem/physiol Actions

In mammary epithelial cells, protein tyrosine phosphatase, non-receptor type 6 (PTPN6) controls EGFR (epidermal growth factor receptor) signaling. It participates in the JAK/STAT (janus kinase/signal transducers and activators of transcription) signaling pathway. PTPN6 regulates cytokine receptors like interleukin- 3 (IL-3) and erythropoietin.

Unit Definition

One unit will hydrolyze 1 nmol p-nitrophenyl phosphate per minute at pH 7.4 and 30°C.

Physical form

Formulated in 25 mM Tris-HCl, pH 8.0, 75 mM NaCl, 0.05% Tween-20, 50% glycerol, 2 mM EDTA, 1 mM DTT, and 10 mM glutathione.

Preparation Note

Thaw on ice. Upon first thaw, briefly spin tube containing enzyme to recover full content of the tube. Aliquot enzyme into single use aliquots. Store remaining undiluted enzyme in aliquots at -70°C. Note: Enzyme is very sensitive to freeze/thaw cycles.

The SH2 domain-containing tyrosine phosphatase PTPN6 (SHP-1, PTP1C, HCP) is a 68 kDa cytoplasmic protein primarily expressed in hematopoietic cell development, proliferation and receptor-mediated mitogenic signaling pathways. By means of direct dephosphorylation, it down-regulates a broad spectrum of growth-promoting receptors
