It may be located at various distances and in either orientation upstream from, downstream from or within a structural gene.  When bound by a specific transcription factor it increases the levels of expression of the gene, but is not sufficient alone to cause expression. Distinguished from a promoter, that is alone sufficient to cause expression of the gene when bound.","code":"P97","type":"DEFINITION","source":"NCI"}],"properties":[{"code":"P322","type":"Contributing_Source","value":"CTRP"},{"code":"P366","type":"Legacy Concept Name","value":"Enhancer"},{"code":"P106","type":"Semantic_Type","value":"Nucleotide Sequence"},{"code":"P207","type":"UMLS_CUI","value":"C0086222"}]}
