  TITLE     Characterization of a SpAN promoter sufficient to mediate correct
            spatial regulation along the animal-vegetal axis of the sea urchin

  REMARK    GeNet staff at the IHC&DB created this entry from the original journal 
            article. This sequence comes from Fig. 5 and 1.
COMMENTS    Sequences within 300 bp upstream of the transcription start site are 
            sufficient for high-level activity and correct non-vegetal expression of SpAN.CAT 
            transgenes. However this region is not sufficienet to shut down the
            transcription from the endogenous SpAN gene shortly after very 
            blastula stage. This sequence contains at least six separable regions of
            protein-DNA interactions.  All identified sites confer positive regulation.
            Sites I, II, IV and V bind distinct factors, while sites III and VI bind 
            SpGCF1 factor. Site II contains CCAAT box. Sies II and V are essential for 
            high-level promoter activity. SpAN probes containing sites IV and II were 
            competed efficiently by SpHE competitor fragments containing correspondingly
            SpHE sites IV and SpHE sites V and IV.
