This class of zinc fingers can have a variety of functions such as binding RNA and mediating protein-protein interactions, but is best known for its role in sequence-specific DNA-binding proteins such as Zif268 (Egr1). In such proteins, individual zinc finger domains typically occur as tandem repeats with two, three, or more fingers comprising ...
Zinc finger Y-chromosomal protein is a protein that in humans is encoded by the ZFY gene of the Y chromosome. [3] [4] This gene encodes a zinc finger-containing protein that may function as a transcription factor. This gene was once a candidate gene for the testis-determining factor (TDF) and was erroneously referred to as TDF. [4]
In molecular biology, a RING (short for Really Interesting New Gene) finger domain is a protein structural domain of zinc finger type which contains a C 3 HC 4 amino acid motif which binds two zinc cations (seven cysteines and one histidine arranged non-consecutively).
This gene on the X chromosome is structurally similar to a related gene on the Y chromosome ().It encodes a member of the krüppel C2H2-type zinc-finger protein family. The full-length protein contains an acidic transcriptional activation domain (AD), a nuclear localization sequence (NLS) and a DNA binding domain (DBD) consisting of 13 C2H2-type zinc fingers.
ZXDC is a protein composed of 455 amino acids in humans, with a molecular weight of approximately 49.9 kDa. Near its C-terminus, the protein has two C2H2-type zinc finger domains that are likely to be involved in DNA binding and transcriptional control. A flexible linker region that separates
Transcriptional repressor CTCF also known as 11-zinc finger protein or CCCTC-binding factor is a transcription factor that in humans is encoded by the CTCF gene. [ 5 ] [ 6 ] CTCF is involved in many cellular processes, including transcriptional regulation , insulator activity, V(D)J recombination [ 7 ] and regulation of chromatin architecture.
Zinc finger protein chimera are chimeric proteins composed of a DNA-binding zinc finger protein domain and another domain through which the protein exerts its effect. The effector domain may be a transcriptional activator (A) or repressor (R), [ 1 ] a methylation domain (M) or a nuclease (N).
Zinc finger is a small structural motif of protein that allows protein binding to DNA or RNA molecule that is characterized by the coordination of one or more zinc ions (Zn 2+) in order to stabilize the fold. Ikaros displays crucial functions in the hematopoietic system and is a known regulator of immune cells development, mainly in early B ...
