Cartoon representation of the protein Zif268 (blue) containing three zinc fingers in complex with DNA (orange). The coordinating amino acid residues and zinc ions (green) are highlighted. 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
The BED finger is an about 50 to 60 amino acid residues domain that contains a characteristic motif with two highly conserved aromatic positions, as well as a shared pattern of cysteines and histidines that is predicted to form a zinc finger.
The encoded protein has five LIM domains, each domain forming two zinc fingers, which permit interactions which regulate cell shape and migration. A pseudogene of this gene is located on chromosome 4. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2011].
It is also known as Smad-interacting zinc finger protein 2 (SIZN2), para-neoplastic Ma antigen family member 7b (PNMA7B), and LOC644353. [4] [5] Other names such as zinc finger, CCHC domain containing 12 pseudogene 1, P0CG32, ZCC18_HUMAN had been used to describe this protein. ZCCHC18 belongs to the ZCCHC12 family or para-neoplastic Ma (PNMA).
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. These zinc fingers are thought to be involved in protein-protein interactions. The structure of the ZZ domain shows that it belongs to the family of cross-brace zinc finger ...
The protein encoded by this gene belongs to the C2H2-type zinc-finger protein family. The exact function of this gene is not known, however, zinc-finger proteins are known to interact with DNA and function as transcription regulators. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.
This domain was first identified as a zinc finger at the C terminus of AN1 SWISSPROT, a ubiquitin-like protein in Xenopus laevis. [1] The AN1-type zinc finger contains six conserved cysteines and two histidines that could potentially coordinate 2 zinc atoms. Certain stress-associated proteins (SAP) contain AN1 domain, often in combination with ...
In molecular biology, GATA zinc fingers are zinc-containing domains found in a number of transcription factors (including erythroid-specific transcription factor and nitrogen regulatory proteins). Some members of this class of zinc fingers specifically bind the DNA sequence (A/T)GATA(A/G) in the regulatory regions of genes ., [ 1 ] giving rise ...
