Gene Variant Descriptions | TP53 R175H is a hotspot mutation that lies within the DNA binding domain of the Tp53 protein (PMID: 22713868). R175H leads to increased Nek2 expression in culture (PMID: 35088582) and results in a loss of DNA binding, decreased activation of Tp53 targets and interferes with activation by wild-type Tp53, resistance to apoptosis, failure of G1 arrest, decreased genomic stability, promotes tumorigenesis, proliferation, migration, invasion, and stability, and additionally confers a gain of function to Tp53, resulting in aberrant activation of gene transcription and enhanced cell migration (PMID: 10713666, PMID: 22114072, PMID: 19881536, PMID: 14743206, PMID: 31395785, PMID: 37030635). |
