CC -!- FUNCTION: Transcription factor that binds to DNA at the consensus
CC sequence 5'-CAG[GC]TG-3' (By similarity). Positively regulates the
CC determination of retinal ganglion cell fate and formation of the optic
CC nerve and retino-hypothalamic tract (PubMed:9390513). Required for
CC retinal circadian rhythm photoentrainment (By similarity). Plays a role
CC in brainstem auditory signaling and binaural processing (By
CC similarity). Regulates the differentiation of olfactory receptor
CC neurons (PubMed:12454929). During retinal neurogenesis, activates the
CC transcription of several genes such as brn3d, coe3, cbfa2t2, glis2,
CC elrC and xgadd45-gamma (PubMed:11401395, PubMed:16112102).

CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:Q8N100}.
CC Perikaryon {ECO:0000250|UniProtKB:Q9Z2E5}. Cell projection, axon
CC {ECO:0000250|UniProtKB:Q9Z2E5}.
CC -!- DEVELOPMENTAL STAGE: First detected at stage 17 as two symmetric
CC patches in the region of the presumptive olfactory placode. Expressed
CC in the pineal at stage 23, and in the eye starting from stage 24. By
CC stage 27, strongly expressed in retina, olfactory placodes and pineal.
CC At stage 32, expression strongly decreases in olfactory placodes and
CC pineal but is maintained in the neuroretina. At stage 41, expression is
CC restricted to the ciliary marginal zone of the retina.

CC -!- INDUCTION: Inhibited by Notch and ESR1.
