Tumor-Specific Neoantigen (Frameshift Peptide) (Frameshift Peptide Neoantigen)

Target
Frameshift Peptide Neoantigen
Molecular classification
Peptide, Antigen, Neoantigen
01

Overview

Tumor-specific neoantigen (frameshift peptide) refers to unique protein fragments generated exclusively within tumors due to coding region insertions/deletions that shift the genetic reading frame. These highly immunogenic antigens serve as ideal targets for next-generation cancer immunotherapies because they are absent from normal tissues, reducing autoimmune risk while enabling precise immune targeting against malignant cells.
