RT Drosophila embryo.";
RL Proc. Natl. Acad. Sci. U.S.A. 83:4809-4813(1986).
CC -!- FUNCTION: Sequence-specific transcription factor which is part of a
CC developmental regulatory system that provides cells with specific
CC positional identities on the anterior-posterior axis. Required for
CC proper head development.
CC -!- SUBCELLULAR LOCATION: Nucleus.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=2;
CC Name=Long;
CC IsoId=P10105-1; Sequence=Displayed;
CC Name=Short;
CC IsoId=P10105-2; Sequence=VSP_002397;
CC -!- TISSUE SPECIFICITY: During embryogenesis, expressed in mandibular lobe,
CC hypopharyngeal organ, neural and epidermal cells of procephalic lobe,
CC sensory cells of clypeolabrum, posterior midgut, thoracic and abdominal
CC segments. {ECO:0000269|PubMed:2461299, ECO:0000269|PubMed:3014511}.
CC -!- DEVELOPMENTAL STAGE: Expressed both maternally and zygotically. High
CC expression in embryos and third instar larvae, lower expression in
CC pupae. {ECO:0000269|PubMed:2461299}.
CC -!- SIMILARITY: Belongs to the Antp homeobox family. Labial subfamily.
CC {ECO:0000305}.
CC -!- CAUTION: It is uncertain whether Met-1, Met-2 or Met-7 is the
CC initiator. {ECO:0000305}.
