Also known as: otx3; otx1a; otx1l
Summary: Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Acts upstream of or within brain development and retinal pigment epithelium development. Predicted to be active in nucleus. Is expressed in several structures, including anterior neural keel; axis; brain; immature eye; and neural plate. Orthologous to human OTX1 (orthodenticle homeobox 1).

What's a GeneRIF?

These findings suggest that one or more Otx targets in addition to mitfa and mitfb, possibly another mitf family member, are necessary for development of the retinal pigmented epithelium in zebrafish.
Title: Otx but not Mitf transcription factors are required for zebrafish retinal pigment epithelium development.
The Zona limitans intrathalamica is induced within the competence area established by Otx1l/2, and is posteriorly restricted by Irx1b.
Title: Otx1l, Otx2 and Irx1b establish and position the ZLI in the diencephalon.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
