Initiator element
The initiator element (Inr), sometimes also called initiator motif, is a core promoter that is similar in function to the Pribnow box (for prokaryotes) or the TATA box (for eukaryotes). It has the consensus sequence YYANWYY.[lower-alpha 1][1] Similarly to the TATA box, the Inr element facilitates the binding of transcription Factor II D (TAF).[1]
TATA box and Inr are usually mutually exclusive.
