Function

[RC3H1_MOUSE] 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 (PubMed:23663784). Binds to CDE and promotes mRNA deadenylation and degradation. This process does not involve miRNAs. In follicular helper T (Tfh) cells, represses of ICOS and TNFRSF4/Ox40 expression, thus preventing spontaneous Tfh cell differentiation, germinal center B-cell differentiation in the absence of immunization and autoimmunity. In resting or LPS-stimulated macrophages, controls inflammation by suppressing TNF expression. Also recognizes CDE in its own mRNA and in that of paralogous RC3H2, possibly leading to feedback loop regulation.^[1] ^[2] ^[3] ^[4] ^[5] ^[6] ^[7]

Publication Abstract from PubMed

The RNA-binding protein Roquin is required to prevent autoimmunity. Roquin controls T-helper cell activation and differentiation by limiting the induced expression of costimulatory receptors such as tumor necrosis factor receptor superfamily 4 (Tnfrs4 or Ox40). A constitutive decay element (CDE) with a characteristic triloop hairpin was previously shown to be recognized by Roquin. Here we use SELEX assays to identify a novel U-rich hexaloop motif, representing an alternative decay element (ADE). Crystal structures and NMR data show that the Roquin-1 ROQ domain recognizes hexaloops in the SELEX-derived ADE and in an ADE-like variant present in the Ox40 3'-UTR with identical binding modes. In cells, ADE-like and CDE-like motifs cooperate in the repression of Ox40 by Roquin. Our data reveal an unexpected recognition of hexaloop cis elements for the posttranscriptional regulation of target messenger RNAs by Roquin.

Roquin recognizes a non-canonical hexaloop structure in the 3'-UTR of Ox40.,Janowski R, Heinz GA, Schlundt A, Wommelsdorf N, Brenner S, Gruber AR, Blank M, Buch T, Buhmann R, Zavolan M, Niessing D, Heissmeyer V, Sattler M Nat Commun. 2016 Mar 24;7:11032. doi: 10.1038/ncomms11032. PMID:27010430^[8]
