Sequence analysis of the 5'-flanking region of the CD69 gene revealed the presence of a potential TATA element 30 base pairs upstream of the major transcription initiation site and several putative binding sequences for inducible transcription factors ( NF-kappa B , Egr-1 , AP-1 ), which might mediate the inducible expression of this gene.
