Official Full Name
activating transcription factor 4
Background
This gene encodes a transcription factor that was originally identified as a widely expressed mammalian DNA binding;protein that could bind a tax-responsive enhancer element in the LTR of HTLV-1. The encoded protein was also isolated;and characterized as the cAMP-response element binding protein 2 (CREB-2). The protein encoded by this gene belongs to;a family of DNA-binding proteins that includes the AP-1 family of transcription factors, cAMP-response element binding;proteins (CREBs) and CREB-like proteins. These transcription factors share a leucine zipper region that is involved in;protein-protein interactions, located C-terminal to a stretch of basic amino acids that functions as a DNA binding;domain. Two alternative transcripts encoding the same protein have been described. Two pseudogenes are located on the;X chromosome at q28 in a region containing a large inverted duplication.
