tokens: Detailed structural analysis of the first 12 cDNAs ( HZF 1-10 ) and a partial characterization of HZF 11-42 revealed that a common feature of human Kruppel-related zinc finger proteins is the presence of tandem arrays of zinc fingers ranging in number from 3 to over 20 that are preferentially located in the carboxy-terminal regions of the proteins .
