| + | [https://www.uniprot.org/uniprot/RC3H1_MOUSE 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.<ref>PMID:15917799</ref> <ref>PMID:18172933</ref> <ref>PMID:20412057</ref> <ref>PMID:20639877</ref> <ref>PMID:23663784</ref> <ref>PMID:23583643</ref> <ref>PMID:23583642</ref> | ||
