KRA-533, a potent KRAS agonist, directly targets the GTP GDP binding pocket within the KRAS protein, inhibiting GTP cleavage. This inhibition leads to the buildup of constitutively active GTP-bound KRAS, which subsequently activates both apoptotic and autophagic cell death pathways specifically 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.
