KRASG12D

Target
KRASG12D
Molecular classification
Small GTPase, Oncogene
01

Overview

KRASG12D is a mutant form of the KRAS protein, where glycine at position 12 is replaced by aspartic acid (G12D). This mutation impairs intrinsic GTPase activity, resulting in constitutive activation of KRAS and persistent downstream signaling—an oncogenic driver in several cancers, especially pancreatic cancer. Therapeutic targeting focuses on noncovalent inhibitors binding to unique pockets on the mutant protein.
