AP-2 beta (human)

Overview
AP-2 beta Sequence-specific DNA-binding protein that interacts with inducible viral and cellular enhancer elements to regulate transcription of selected genes. AP-2 factors bind to the consensus sequence 5'-GCCNNNGGC-3' and activate genes involved in a large spectrum of important biological functions including proper eye, face, body wall, limb and neural tube development. They also suppress a number of genes including MCAM/MUC18, C/EBP alpha and MYC. AP-2-beta appears to be required for normal face and limb development and for proper terminal differentiation and function of renal tubular epithelia. Binds DNA as a dimer. Can form homodimers or heterodimers with other AP-2 family members. Interacts with CITED4. Interacts with UBE2I. Interacts with KCTD1; this interaction represses transcription activation. Interacts with CITED2 (via C-terminus); the interaction stimulates TFAP2B-transcriptional activity. Belongs to the AP-2 family. 2 isoforms of the human protein are produced by alternative splicing.
