Question

Quizplus · Accepted Answer

A homeodomain is a protein domain that is encoded by a homeobox, a conserved DNA sequence found in genes that regulate pattern formation in development. It has a characteristic helix-turn-helix structure that allows it to bind specifically to DNA in the major groove, often at regulatory regions of target genes. It is not a transmembrane protein and does not bind to DNA at random sequences.
