Description
The paired domain, a ~126 amino acid DNA-binding domain, is found in eukaryotic transcription regulatory proteins involved in embryogenesis. Initially identified in Drosophila’s paired (prd) protein, it typically resides in the N-terminal region and may be followed by an octapeptide, a homeodomain, or a Pro-Ser-Thr-rich C terminus. Paired domain proteins act as transcription repressors or activators, with DNA-binding specificity mediated by three subdomains. Crystal structures reveal a bipartite DNA-binding paired domain: an N-terminal subdomain (PAI) and a C-terminal subdomain (RED), linked by a flexible linker. Both subdomains contain a helix-turn-helix motif that binds DNA's major groove, while the linker may bind the minor groove. Variations in domain usage across Pax proteins and isoforms determine sequence specificity.
