Ring Finger Protein 41 (RNF41)

E3 ubiquitin-protein ligase NRDP1 is an enzyme contains a RING finger, a motif present in a variety of functionally distinct proteins and known to be involved in protein-protein and protein-DNA interactions. The specific function of this protein has not yet been determined. Three alternatively spliced transcript variants encoding two distinct isoforms have been reported.

The RING finger domain is a type of zinc finger which contains a Cys₃HisCys₄ amino acid motif which binds two zinc cations. This protein domain contains from 40 to 60 amino acids. The acronym RING stands for Really Interesting New Gene.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.
