Abstract |
Human RING finger protein 141 (RFP141) is a germ cell-specific transcription factor during spermatogenesis. We synthesized a compact construct encoding the C-terminal zinc finger of RFP141 (RFP141C peptide). Herein we determined the solution structure of the RFP141C peptide by nuclear magnetic resonance (NMR). Moreover, NMR data and the chemical modification of cysteine residues demonstrated that the RFP141C peptide binds to two zinc atoms in a cross-brace arrangement. The Simple Modular Architecture Research Tool database predicted the structure of RFP141C as a RING finger. However, the actual structure of the RFP141C peptide adopts an atypical compact C3 HC4 -type RING fold. The position and range of the helical active site of the RFP141C structure were elucidated at the atomic level. Therefore, structural analysis may allow RFP141C to be used for designing an artificial RING finger possessing specific ubiquitin-conjugating enzyme (E2)-binding capabilities.
