NCIt synonyms : MGC138366; 53BP1; p202; FLJ41424; Tumor Protein p53 Binding Protein 1 wt Allele; Tumor Protein 53-Binding Protein, 1 Gene; TDRD30; p53BP1; Tumor Protein p53-Binding Protein, 1 Gene;
NCIt definition : Human TP53BP1 wild-type allele is located in the vicinity of 15q15.3 and is approximately
103 kb in length. This allele, which encodes TP53-binding protein 1, may be involved
in the regulation of both mitosis and nonhomologous end joining after DNA damage.;
NCIt note : The TP53BP1 gene in conjuction with BRCA1 mutations may be associated in breast tumorigenesis.; TP53BP1 protein is associated with promoting non-homologous end-joining of DNA, a
process which may lead to chromosomal rearrangements and gene fusions. Studies published
in April 2010 (Cell, April 1, 2010) indicate that suppressing the expression of TP53BP1
can result in restoration of DNA break resolution through homologous recombination.;
