Application Abreviews Notes
WB 1/1000 - 1/10000. Predicted molecular weight: 32 kDa.
  • Application notes
    Is unsuitable for IHC-P.
  • Target

    • Function
      Probably plays a role in the development of the brain and the sense organs. Can bind to the BCD target sequence (BTS): 5'-TCTAATCCC-3'.
    • Tissue specificity
      Expressed in brain.
    • Involvement in disease
      Defects in OTX2 are the cause of microphthalmia syndromic type 5 (MCOPS5) [MIM:610125]. Microphthalmia is a clinically heterogeneous disorder of eye formation, ranging from small size of a single eye to complete bilateral absence of ocular tissues. Up to 80% of cases of microphthalia occur in association with syndromes that include non-ocular abnormalities. MCOPS5 patients manifest unilateral or bilateral microphthalmia/clinical anophthalmia and variable additional features including coloboma, microcornea, cataract, retinal dystrophy, hypoplasia or agenesis of the optic nerve, agenesis of the corpus callosum, developmental delay, joint laxity, hypotonia, and seizures.
    • Sequence similarities
      Belongs to the paired homeobox family. Bicoid subfamily.
      Contains 1 homeobox DNA-binding domain.

    Thank you for contacting us.

    The immunogen for ab92515 shares 100% identity with OTX1, so cross reactivity is predicted.

    I hope this information is helpful to you. Please do not hesitate to contact us if you need any mor...
