Ready-to-use ELISA kits are available for the detection of RING CCCH (C3H) domains 1, an alias of the protein, ring finger and CCCH-type domains 1. The official gene symbol is RC3H1. The protein, with a mass of 125.7 kDa and length of 1133 residues, is reported to be cytoplasmic. It may be known by other names, including: ROQUIN, RNF198, RING finger protein 198, RING finger and CCCH-type zinc finger domain-containing protein 1, RING finger and C3H zinc finger protein 1, and roquin-1.
