| Modification Notes |
Zinc-finger proteins contain DNA-binding domains and have a wide variety of functions, most of which encompass some form of transcriptional activation or repression. The majority of zinc-finger proteins contain a Krüppel-type DNA binding domain and a KRAB domain, which is thought to interact with KAP1, thereby recruiting histone modifying proteins. ZNF133 (Zinc finger protein 133), also known as ZNF150 (Zinc finger protein 150), is a 654 amino acid transcriptional regulator that is expressed in heart, brain, placenta, lung, liver, skeletal muscle, kidney and pancreas. The KRAB domain derived from ZNF133 is suggested to be a potent transcriptional repression domain and its repression activity may be enhanced by PIAS 1 (Protein inhibitor of activated STAT protein 1). |
