KRAB

It belongs to the N-terminal domain of zinc finger protein and binds to some DNA binding domains to inhibit transcription. The KRAB domain is a protein-protein interaction domain which can bind to a variety of synergistic transcriptional inhibitors and transcription factors, so that KRAB zinc finger proteins as transcriptional factors or transcriptional regulators plays a transcriptional inhibitory function dependently on DNA binding.

2.Caution

Different KRAB domains have different silencing effects on target genes, regardless of cell types. The KRAB protein domain must be linked to the DNA binding domains to play an inhibitory role.
