Promoter
The region on DNA to which RNA polymerase binds and initiates transcription (of RNA). The promoter "promotes" the transcription (expression) of that gene, but the promoter's impact on the timing/degree of gene expression is itself regulated by the molecules that bind to the promoter. For example, the "binding" of RNA polymerase causes transcription-of-RNA to begin, and the "binding" to promoter of other STATs (i.e., signal transducers and activators of transcription) can regulate the degree to which a given gene is expressed.
A promoter is a region of DNA (deoxyribonucleic acid) which lies "upstream" of the transcriptional initiation site of a gene. The promoter controls where (e.g., which portion of a
plant, which organ within an animal, etc.) and when
(e.g., which stage in the lifetime of an organism)
that the gene is expressed. For example, the promoter
named "Bce4" is "seed-specific" [i.e., it
only "promotes" the expression of a given gene's
product (e.g., protein, fatty acid, amino acids, etc.)
within a plant's seed].
