SHP-2 Protein, Mouse (HEK293, His)

SHP-2 Protein functions downstream of diverse receptor and cytoplasmic tyrosine kinases, participating in signal transduction from the cell surface to the nucleus. It positively regulates the MAPK pathway and dephosphorylates key proteins like GAB1, ARHGAP35, EGFR, ROCK2, CDC73, and SOX9. Additionally, SHP-2 dephosphorylates NEDD9/CAS-L to modulate cellular processes. SHP-2 Protein, Mouse (HEK293, His) is the recombinant mouse-derived SHP-2 protein, expressed by HEK293 , with C-His labeled tag. The total length of SHP-2 Protein, Mouse (HEK293, His) is 593 a.a., with molecular weight of ~65 kDa.

SHP-2 protein functions downstream of various receptor and cytoplasmic protein tyrosine kinases, participating in signal transduction from the cell surface to the nucleus. It positively regulates the MAPK signal transduction pathway and exhibits dephosphorylation activity towards substrates such as GAB1, ARHGAP35, EGFR, ROCK2 (at 'Tyr-722,' enhancing its RhoA binding activity), CDC73, and tyrosine-phosphorylated NEDD9/CAS-L. Notably, SHP-2 plays a role in the inactivation of SOX9 by dephosphorylating its tyrosine residues, leading to the promotion of ossification. Through its multifaceted dephosphorylation activities, SHP-2 is a critical player in modulating key signaling pathways involved in cell growth, differentiation, and cellular responses to various stimuli.

Measured by its ability to dephosphorylate a tyrosine residue in a peptide containing the EGFR Y992 phosphorylation site. The specific activity is 34.1661 µmol/min/mg, measured under the described conditions.

Approximately 65 kDa

Greater than 95% as determined by reducing SDS-PAGE

Lyophilized powder

Lyophilized from a 0.2 μm filtered solution of 20 mM PB, 150 mM NaCl, pH 7.4.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
