Database IDHIV0000731
UniProt IDQ7LFL8
Primary gene name(s)CXXC5
Synonym gene name(s)unknown
Protein nameCXXC-type zinc finger protein 5
Protein functionMay indirectly participate in activation of the NF-kappa-B and MAPK pathways. Acts as a mediator of BMP4-mediated modulation of canonical Wnt signaling activity in neural stem cells, By similarity. Required for DNA damage-induced ATM phosphorylation, p53 activation and cell cycle arrest. Involved in myelopoiesis. Transcription factor. Binds to the oxygen responsive element of COX4I2 and represses its transcription under hypoxia conditions, 4% oxygen, as well as normoxia conditions, 20% oxygen, PubMed:23303788. May repress COX4I2 transactivation induced by CHCHD2 and RBPJ, PubMed:23303788. {ECO:0000250, ECO:0000269|PubMed:19182210, ECO:0000269|PubMed:19557330, ECO:0000269|PubMed:23303788}.
