Otx2 Antibody

Orthodenticle homeobox 2 is also known as CPHD6 or MCOPS5. The OTX2 gene encodes a member of the bicoid subfamily of homeodomain-containing transcription factors. Otx2 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). Otx2 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.
