CC -!- FUNCTION: Acts as a transcriptional activator (PubMed:8290353,
CC PubMed:7935408). Acts by binding to sequences related to the consensus
CC octamer motif 5'-ATGCAAAT-3' in the regulatory regions of its target
CC genes (PubMed:7935408). Involved in the auditory system development,
CC required for terminal differentiation of hair cells in the inner ear
CC (PubMed:8637595). {ECO:0000269|PubMed:7935408,
CC ECO:0000269|PubMed:8290353, ECO:0000269|PubMed:8637595}.
CC -!- SUBUNIT: Interacts with ISL1 (PubMed:24643061).
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:Q15319}. Cytoplasm
CC {ECO:0000250|UniProtKB:Q15319}. Note=Preferentially localized in the
CC nucleus. {ECO:0000250|UniProtKB:Q15319}.
CC -!- TISSUE SPECIFICITY: Brain.
CC -!- DEVELOPMENTAL STAGE: Expressed in developing spinal cord from 13 dpc to
CC postanal day 1, not expressed in adults (PubMed:8290353). Expressed by
CC few neurons of dorsal root ganglion from, at least, 10.5 dpc to 15.5
CC dpc (PubMed:22326227). {ECO:0000269|PubMed:22326227,
CC ECO:0000269|PubMed:8290353}.
CC -!- DISRUPTION PHENOTYPE: Mutants are deaf and show deficits in balance and
CC coordination that become severe at about P14 and exhibit hyperactivity
CC by 5-6 weeks. {ECO:0000269|PubMed:8637595}.
CC -!- SIMILARITY: Belongs to the POU transcription factor family. Class-4
CC subfamily. {ECO:0000305}.
