CC -!- FUNCTION: Transcriptional repressor. {ECO:0000250|UniProtKB:Q9H334}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:Q9H334}.
CC -!- TISSUE SPECIFICITY: Shows complex and dynamic expression during early
CC embryonic development. Prominent in many regions of the developing
CC central nervous system, particularly in midbrain-hindbrain boundary,
CC hindbrain and spinal cord. Strongly expressed in the retina, ear,
CC branchial arches, hatching gland, heart, pronephric duct, gut,
CC proctodeum, pectoral fin and swim bladder.
CC {ECO:0000269|PubMed:17876603}.
CC -!- DEVELOPMENTAL STAGE: Expressed both maternally and zygotically with
CC continuous expression from the zygote to the early larva. Expression
CC dramatically decreases at 30 and 50% epiboly stages, then increases
CC from midgastrulaion onwards, being maintained at a high level until the
CC protruding-mouth stage. {ECO:0000269|PubMed:17876603}.
CC -!- DOMAIN: The leucine-zipper is required for dimerization and
CC transcriptional repression. {ECO:0000250|UniProtKB:P58462}.
