The human T cell lymphotropic retrovirus type I ( HTLV - I ) trans - activator , Tax , interacts specifically with the basic - domain / leucine - zipper ( bZip ) protein , cAMP response element binding protein ( CREB ) , bound to the viral Tax - responsive element consisting of three imperfect 21 - base pair repeats , each with a cAMP response element core flanked by G / C - rich sequences .
 GENE: Tax; GENE: basic - domain / leucine - zipper ( bZip ) protein; GENE: cAMP response element binding protein; GENE: CREB; GENE: viral Tax - responsive element
