A zinc finger is a small protein structural motif that is characterized by the coordination of one or more zinc ions (Zn 2+) which stabilizes the fold. The term zinc finger was originally coined to describe the finger-like appearance of a hypothesized structure from the African clawed frog (Xenopus laevis) transcription factor IIIA.
In molecular biology the ZZ-type zinc finger domain is a type of protein domain that was named because of its ability to bind two zinc ions. [1] These domains contain 4-6 Cys residues that participate in zinc binding (plus additional Ser/His residues), including a Cys-X2-Cys motif found in other zinc finger domains.
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]
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.

The human gene maps to chromosome 2 q32.1 and consists of 4 exons that code for a protein of 1210 amino acids (137 kDa). [6] Little is known about the characteristics and function of the encoded protein. However, the protein sequence codes for a domain characteristic of a classical C 2 H 2-type zinc finger near the N-terminal end. [6] [7]
LIM domains are protein structural domains, composed of two contiguous zinc fingers, separated by a two-amino acid residue hydrophobic linker. [1] The domain name is an acronym of the three genes in which it was first identified (LIN-11, Isl-1 and MEC-3). [2]
Zinc finger transcription factors or ZF-TFs, are transcription factors composed of a zinc finger-binding domain and any of a variety of transcription-factor effector-domains that exert their modulatory effect in the vicinity of any sequence to which the protein domain binds. [1] Zinc finger protein transcription factors can be encoded by genes ...
