Cellular Tumor Antigen p53 R175H (p53 R175H)

Target
p53 R175H
Molecular classification
Transcription factor, Tumor suppressor, Neoantigen
01

Overview

Cellular tumor antigen p53 R175H is a mutant form of the human tumor suppressor protein p53. The R175H mutation results in loss of wild-type tumor-suppressive functions and confers new oncogenic properties, promoting cancer cell proliferation, migration, invasion, and metastasis. It represents a key oncogenic driver and an attractive target for next-generation precision therapies.
