RNF212: Proteins and Enzymes

RNF212, also known as Probable E3 SUMO-protein ligase RNF212, has 6 isoforms, a 297 amino acid isoform that is 33 kDa, a 123 amino acid isoform that is 14 kDa, a 192 amino acid isoform that is 22 kDa, a 280 amino acid isoform that is 31 kDa, a 232 amino acid isoform that is 26 kDa, and a 273 amino acid isoform that is 30 kDa. This protein may function as a ubiquitin ligase and may be involved in meiotic recombination, regulates crossing-over during meiosis: required to couple chromosome synapsis to the formation of crossover-specific recombination complexes, localizes to recombination sites and stabilizes meiosis-specific recombination factors, may act as a SUMO E3 ligase that mediates sumoylation of target proteins MSH4 and/or MSH5, leading to enhance their binding to recombination sites, and acts as a limiting factor for crossover designation and/or reinforcement.RNF212 protein is being studied for its involvement in recombination rate qtl 1 disorder. Little is currently known about this protein interactions with other proteins.
