CC -!- FUNCTION: Transcriptional activator. Induces neural-specific gene
CC expression to act as a key regulator of neural differentiation.
CC {ECO:0000269|PubMed:10559482, ECO:0000269|PubMed:7720579}.
CC -!- SUBCELLULAR LOCATION: Nucleus.
CC -!- TISSUE SPECIFICITY: From embryonic stage 10, expressed in the Spemann's
CC organizer. During gastrulation, expressed in both the involuting
CC mesoderm and the overlying neuroectoderm. During the neural plate and
CC neural fold stages, expressed in the entire neuroectoderm with
CC expression in discrete regions of the developing nervous system
CC persisting at later stages. Transiently expressed in the pronephros
CC from stages 24-32. In adults, expressed in the kidney and brain.
CC {ECO:0000269|PubMed:1717323, ECO:0000269|PubMed:7720579}.
CC -!- DEVELOPMENTAL STAGE: First expressed at embryonic stage 9, with
CC expression increasing at neurula stage and again at the tailbud stage.
CC Expression persists through development to adulthood.
CC {ECO:0000269|PubMed:1717323, ECO:0000269|PubMed:7720579}.
CC -!- INDUCTION: By nog, zic1 and zic3. {ECO:0000269|PubMed:10559482,
CC ECO:0000269|PubMed:7720579}.
CC -!- SIMILARITY: Belongs to the POU transcription factor family. Class-3
CC subfamily. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=CAA41781.1; Type=Erroneous initiation; Evidence={ECO:0000305};
