Our results indicate that the KRAB domain present in the non - finger region of many ZFP genes quenches transcription possibly due to specific protein - protein interactions between the KRAB - A domain and components of the proximal transcriptional apparatus .
 GENE: KRAB domain; GENE: ZFP genes; GENE: KRAB - A domain
