MCPH1 Antibody

1. Tumor suppressor functions of MCPH1/BRIT1 and BRCA1; links with the inactivation of the functional form of hTERT and the activation of dominant negative splice variants of hTERT. PMID: 29860064

24. The MCPH1 promoter region was sequenced in human, chimpanzee and rhesus macaque; sequence comparison of vertebrate species suggested that the identified E2F1 binding motif is primate specific. PMID: 22136275
25. It was shown that MCPH1 directly binds to the promoter of human telomerase reverse transcriptase and represses telomerase activity. An intact N terminal BRCT domain was essential for the proper inhibiting function of MCPH1. PMID: 22240313
