Protein Domain : IPR003025

Type:  Family Name:  Transcription factor Otx
Description:  Otx proteins constitute a class of vertebrate homeodomain-containing transcription factors that have been shown to be essential for anteriorhead formation, including brain morphogenesis. They are orthologous to the product of the Drosophila head gap gene, orthodenticle (Otd), and appear toplay similar roles in both, since the developmental abnormalities caused by disruption of these transcription factors in one, can be recovered bysubstitution of the factor(s) from the other. Such studies have provided strong evidence that there exists a conserved genetic programme for insectand mammalian brain development, which presumably arose in a more primitive common ancestor [, ].Two vertebrate orthodenticle-related transcription factors have been indentified, Otx1 and Otx2, which have sizes of 355 and 289 residuesrespectively. They contain a bicoid-like homeodomain, which features a conserved lysine residue at position 9 of the DNA recognition helix, whichis thought to confer high-affinity binding to TAATCC/T elements on DNA [].Otd-like transcription factors have also been found in zebrafish and certain lamprey species.
