Homeobox protein OTX2 is a protein that in humans is encoded by the OTX2 gene.[1][2]

This gene encodes a member of the bicoid sub-family of homeodomain-containing transcription factors. The encoded protein acts as a transcription factor and may play a role in brain and sensory organ development. A similar protein in mice is required for proper forebrain development. Two transcript variants encoding distinct isoforms have been identified for this gene. Other alternative splice variants may exist, but their full length sequences have not been determined.[2]

Mutations in OTX2 can cause eye disorders including anophthalmia and microphthalmia.[3]
