Generic protein structure example

Transcription factor AP-2 beta also known as AP2-beta is a protein that in humans is encoded by the TFAP2B gene.[1][2]

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.[3]

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.[3]
