生物活性

SAH-SOS1A is a peptide-based SOS1/KRAS protein interaction inhibitor. SAH-SOS1A binds to wild-type and mutant KRAS (G12D, G12V, G12C, G12S, and Q61H) with nanomolar affinity (EC50=106-175 nM), directly and independently blocks nucleotide association, impairs KRAS-driven cancer cell viability, and exerts its effects by on-mechanism blockade of the ERK-MAPK phosphosignaling cascade downstream of KRAS[1].

体外研究
(In Vitro)

SAH-SOS1A (0.625-40 μM) dose-responsively impairs the viability of cancer cells bearing G12D, G12C, G12V, G12S, G13D, and Q61H mutations with IC50 values in the 5- to 15-μM range. Cancer cells expressing wild-type KRAS, such as HeLa and Colo320-HSR cells, are similarly affected[1].
SAH-SOS1A (5-40 μM; 4 hours) dose-responsively inhibits MEK1/2, ERK1/2, and AKT phosphorylation[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

体内研究
(In Vivo)

SAH-SOS1A (0.2 μL of 10 mM solution; injection; 48 hours; abdomens of D. melanogaster Ras85DV12/ActinGS) treatment notably decreases the phosphorylation state of ERK1/2[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
