UniProt ID: Q90472
FUNCTION: Sequence-specific transcription factor which is part of a developmental regulatory system that provides cells with specific positional identities on the anterior-posterior axis. {ECO:0000250}.
SUBCELLULAR LOCATION: Nucleus.
DEVELOPMENTAL STAGE: First expressed at 15 hours post- fertilization (hpf) in the presumptive proctodeum. At 22 hpf, expressed in the most distal part of the hindgut, the future rectum and the cloacal region; cloacal expression is still detectable until 64 hpf. First detected in the dorsal pre-somitic mesoderm and neural keel at 17 hpf. At 22-26 hpf, expression is restricted to the posterior tip of the trunk, begins to weaken and is undetectable by 40-56 hpf. {ECO:0000269|PubMed:8808402}.
SIMILARITY: Belongs to the Abd-B homeobox family. {ECO:0000305}.
