ID:RC3H1_HUMAN DESCRIPTION: RecName: Full=Roquin; AltName: Full=RING finger and C3H zinc finger protein 1; AltName: Full=RING finger protein 198; FUNCTION: Represses ICOS function, an essential costimulatory receptor for follicular T-cells. May act as an ubiquitin ligase that regulates ubiquitin-dependent control of AU-rich mRNAs by AUF1/HNRPD and HUR/ELAVL1 (By similarity). SUBCELLULAR LOCATION: Cytoplasm (By similarity). Note=Localizes to cytosolic RNA granules, which are sites for regulating mRNA translation and decay, suggesting that it may bind RNA (By similarity). TISSUE SPECIFICITY: Widely expressed. Expressed at higher level in cerebellum, spleen, ovary and liver. SIMILARITY: Contains 1 C3H1-type zinc finger. SIMILARITY: Contains 1 RING-type zinc finger. SEQUENCE CAUTION: Sequence=BAC04186.1; Type=Erroneous initiation; Sequence=CAH70709.1; Type=Erroneous initiation; Sequence=CAH70710.1; Type=Erroneous initiation; Sequence=CAI19417.1; Type=Erroneous initiation; Sequence=CAI19419.1; Type=Erroneous initiation;
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
