tokens: PKNbeta had high sequence homology with PKNalpha , originally isolated PKN , especially in the repeats of charged amino acid rich region with leucine-zipper like sequences ( CZ region / HR1 ) , in the carboxyl-terminal catalytic domain , and in approximately 130 amino acid stretch ( D region / HR2 ) , located between CZ region / HR1 and the catalytic domain .
