Protein Information
Name RC3H1
Synonyms KIAA2025, RNF198
Function Post-transcriptional repressor of mRNAs containing a conserved stem loop motif, called constitutive decay element (CDE), which is often located in the 3'-UTR, as in HMGXB3, ICOS, IER3, NFKBID, NFKBIZ, PPP1R10, TNF and in many more mRNAs (By similarity). Binds to CDE and promotes mRNA deadenylation and degradation. This process does not involve miRNAs (By similarity). In follicular helper T (Tfh) cells, represses of ICOS and TNFRSF4 expression, thus preventing spontaneous Tfh cell differentiation, germinal center B-cell differentiation in the absence of immunization and autoimmunity (By similarity). In resting or LPS- stimulated macrophages, controls inflammation by suppressing TNF expression (By similarity). Also recognizes CDE in its own mRNA and in that of paralogous RC3H2, possibly leading to feedback loop regulation (By similarity).
Cellular Location Cytoplasm, P-body. Note=During stress, such as that induced by arsenite, localizes to cytosolic stress granules.
Tissue Location Widely expressed. Expressed at higher level in cerebellum, spleen, ovary and liver. {ECO:0000269|Ref.3}

RC3H1 Antibody: The ring finger protein RC3H1, also known as Roquin, is a highly conserved member of the RING type ubiquitin ligase protein family whose M199R mutation leads to the excessive production of follicular helper T cells and germinal centers in the sanroque strain of mice, a strain with excessive IL-21 production and high titers of autoantibodies. The complete loss of RC3H1 induces early death and immune deregulation but not autoimmunity in RC3H1-null mice, suggesting that the mutant RC3H1 is more disruptive to the immune system than its complete loss.
