KRAS Mutant Antigen (mKRAS)

Target
mKRAS
Molecular classification
Neoantigen, Peptide, GTPase
01

Overview

KRAS mutant antigens are peptide fragments derived from mutated KRAS proteins, primarily at codon 12, acting as tumor-specific neoantigens presented by HLA class I molecules. These neoantigens can be targeted by immunotherapeutic strategies such as adoptive T cell therapy and bispecific antibodies to elicit anti-tumor immune responses.
