Sts1 Protein, Human, Recombinant (His)

UBASH3B contains a ubiquitin associated domain at the N-terminus, an SH3 domain, and a C-terminal domain with similarities to the catalytic motif of phosphoglycerate mutase. UBASH3B was found to inhibit endocytosis of epidermal growth factor receptor (EGFR) and platelet-derived growth factor receptor. UBASH3B interferes with CBL-mediated down-regulation and degradation of receptor-type tyrosine kinases. It promotes accumulation of activated target receptors, such as T-cell receptors and EGFR, on the cell surface. UBASH3B exhibits tyrosine phosphatase activity toward several substrates including EGFR, FAK, SYK, and ZAP7. Down-regulates proteins that are dually modified by both protein tyrosine phosphorylation and ubiquitination.

Endotoxin	Please contact us for more information.
Formulation	Lyophilized from sterile PBS, pH7.4. Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0. 01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.
Reconstitution	A hardcopy of datasheet with reconstitution instructions is sent along with the products. Please refer to it for detailed information.
Stability & Storage	Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃. Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Shipping	In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
