What (who) is TAZ zinc finger - definition
TAZ zinc finger
In molecular biology, TAZ zinc finger (Transcription Adaptor putative Zinc finger) domains are zinc-containing domains found in the homologous transcriptional co-activators CREB-binding protein (CBP) and the P300. CBP and P300 are histone acetyltransferases (EC) that catalyse the reversible acetylation of all four histones in nucleosomes, acting to regulate transcription via chromatin remodelling.
Zinc finger nuclease
CLASS OF ARTIFICIAL ENZYMES
Zinc finger nucleases; Zinc finger protein nucleases; Zinc-finger nuclease; Nucleasas con dedos de zinc; ZFNs
Zinc-finger nucleases (ZFNs) are artificial restriction enzymes generated by fusing a zinc finger DNA-binding domain to a DNA-cleavage domain. Zinc finger domains can be engineered to target specific desired DNA sequences and this enables zinc-finger nucleases to target unique sequences within complex genomes.
PHD finger
PROTEIN SEQUENCE
Plant homeodomain finger; Plant homeodomain; PHD-type zinc finger
The PHD finger was discovered in 1993 as a Cys4-His-Cys3 motif in the plant homeodomain (hence PHD) proteins HAT3.1 in Arabidopsis and maize ZmHox1a.
