This gene encodes a member of the bicoid subfamily of homeodomain-containing transcription factors. The encoded protein acts as a transcription factor and plays a role in brain, craniofacial, and sensory organ development. The encoded protein also influences the proliferation and differentiation of dopaminergic neuronal progenitor cells during mitosis. Mutations in this gene cause syndromic microphthalmia 5 (MCOPS5) and combined pituitary hormone deficiency 6 (CPHD6). This gene is also suspected of having an oncogenic role in medulloblastoma. Alternative splicing results in multiple transcript variants encoding distinct isoforms. Pseudogenes of this gene are known to exist on chromosomes two and nine. [provided by RefSeq, Jul 2012]
A study in mice demonstrated that the OTX2 was downregulated in the adult brain following fetal alcohol exposure via voluntary maternal drinking, identifying it as a candidate target gene in fetal alcohol spectrum disorders [Laufer et al. DOI:10.1242/Dmm.010975]. In a separate review of rodent models, the OTX2 was positively correlated with ethanol preference in the central amygdala of female HS-CC mice and identified as a top hub node in a female gene network [Hitzemann et al. DOI:10.1016/J.Biopsych.2021.04.016].
