DC-STAMP Domain Containing Protein 1 (DCST1)

DCST1 Contains 1 RING-type zinc finger. RING (Really Interesting New Gene) finger domain is a protein structural domain of zinc finger type which contains a Cys3HisCys4 amino acid motif which binds two zinc cations. This protein domain contains from 40 to 60 amino acids. Many proteins containing a RING finger play a key role in the ubiquitination pathway.

Zinc finger (Znf) domains are relatively small protein motifs that bind one or more zinc atoms, and which usually contain multiple finger-like protrusions that make tandem contacts with their target molecule. They bind DNA, RNA, protein and/or lipid substrates. Their binding properties depend on the amino acid sequence of the finger domains and of the linker between fingers, as well as on the higher-order structures and the number of fingers.
