Octamer-binding transcription factors: genomics and functions.

ABSTRACT: The Octamer-binding proteins (Oct) are a group of highly conserved transcription factors that specifically bind to the octamer motif (ATGCAAAT) and closely related sequences in promoters and enhancers of a wide variety of genes. Oct factors belong to the larger family of POU domain factors that are characterized by the presence of an amino-terminal specific subdomain (POUS) and a carboxyl-terminal homeo-subdomain (POUH). Eleven Oct proteins have been named (Oct1-11), and currently, eight genes encoding Oct proteins (Oct1, Oct2, Oct3/4, Oct6, Oct7, Oct8, Oct9, and Oct11) have been cloned. Oct1 and Oct2 are widely expressed in adult tissues, while other Oct proteins are much more restricted in their expression patterns. Oct proteins are implicated in crucial and versatile biological events,
