Product Specific Information
Antibody detects endogenous levels of total SOS1.
Target Information
Son of sevenless (SOS) is a guanine nucleotide exchange factor that activates Ras in response to growth factor stimulation. Sos1 and its closely related Sos2 paralog contain:
- N-terminal histone-binding domain
- RacGEF catalytic (DH) domain with a PH domain
- Ras exchanger motif (REM) domain
- RasGEF catalytic domain
- C-terminal proline-rich region
Sos1 catalyzes the GDP–GTP exchange within the membrane-bound GTPase Ras, activating the MAPK cascade critical for cellular proliferation, survival, and differentiation. Growth factor stimulation induces phosphorylation of Sos on multiple serine and threonine residues, and phosphorylation within the C-terminus by MAP/ERK kinase disrupts the Grb2–Sos complex.
For Research Use Only. Not for use in diagnostic procedures. Not for resale without express authorization.
