TFAP2B
Human gene and protein
From Wikipedia, the free encyclopedia
Transcription factor AP-2 beta also known as AP2-beta is a protein that in humans is encoded by the TFAP2B gene.[5][6]
Function
AP-2 beta is a member of the AP-2 family of transcription factors. AP-2 proteins form homo- or hetero-dimers with other AP-2 family members and bind specific DNA sequences. They are thought to stimulate cell proliferation and suppress terminal differentiation of specific cell types during embryonic development. Specific AP-2 family members differ in their expression patterns and binding affinity for different promoters. This protein functions as both a transcriptional activator and repressor.[7]
Clinical significance
Mutations in this gene result in autosomal dominant Char syndrome, suggesting that this gene functions in the differentiation of neural crest cell derivatives.[7]
