KRA-533 is an effective KRAS agonist that targets the GTP/GDP binding pocket within the KRAS protein, inhibiting GTP cleavage. This leads to accumulation of the active GTP-KRAS form, promoting apoptosis and autophagic death in cancer cells.
Peptide corresponding to the pp60c-src carboxy terminal regulatory domain; phosphorylated at Tyr527. Binds to pp60c-src and pp60v-src at the SH2 domain, suppressing their tyrosine kinase activity and transforming potential.
