Immunofluorescent analysis of OTX2 in immersion-fixed NTera-2 human testicular embryonic carcinoma cells using an OTX2 polyclonal Antibody (Product # PA5-39887) at 10µg/mL for 3 hours at room temperature. Cells were stained using a fluorescent conjugated anti-Goat IgG secondary antibody (yellow, upper panel) and counterstained with DAPI (blue, lower panel).

OTX2 is a 289 amino acid containing protein encoding a member of the bicoid sub-family of homeodomain-containing transcription factors. It has two known alternative splice variants with distinct isoforms though presence of other isoforms cannot be excluded. The protein is an early marker of endodermal differentiation of embryonic stem cells and may play a role in the development of the brain and the sensory organs. The protein may bind to BCD target sequence (BTS): 5'-TCTAATCCC-3'. Defects in OTX2 are the cause of microphthalmia syndromic type 5 (MCOPS5).
