CC -!- FUNCTION: May function as an output molecule from the suprachiasmatic
CC nucleus (SCN) that transmits behavioral circadian rhythm. May also
CC function locally within the SCN to synchronize output. Potently
CC contracts gastrointestinal (GI) smooth muscle (By similarity).
CC {ECO:0000250, ECO:0000269|PubMed:12024206}.
CC -!- SUBCELLULAR LOCATION: Secreted.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=3;
CC Name=1; Synonyms=Bv8-a;
CC IsoId=Q9QXU7-1; Sequence=Displayed;
CC Name=2; Synonyms=Bv8-b;
CC IsoId=Q9QXU7-2; Sequence=VSP_005220;
CC Name=3;
CC IsoId=Q9QXU7-3; Sequence=VSP_005221;
CC -!- TISSUE SPECIFICITY: Expressed in the SCN and among a few other discrete
CC brain areas, including the islands of Calleja, media l preoptic area of
CC the hypothalamus and the shell of the nucleus accumbens. Highly
CC expressed in testis. In the SCN, expression subjected to high amplitude
CC of circadian oscillation.
CC -!- DEVELOPMENTAL STAGE: Expressed in mid-late pachytene spermatocytes at
CC the stages VII, VIII and IX of the semiferous epithelial cycle.
CC -!- INDUCTION: Activated by CLOCK and BMAL1 heterodimers and light;
CC inhibited by period genes (PER1, PER2 and PER3) and cryptochrome genes
CC (CRY1 and CRY2).
CC -!- SIMILARITY: Belongs to the AVIT (prokineticin) family. {ECO:0000305}.
