Protein functionZinc-finger RNA-binding protein that destabilizes several cytoplasmic AU-rich element, ARE-containing mRNA transcripts by promoting their poly(A tail removal or deadenylation, and hence provide a mechanism for attenuating protein synthesis, PubMed:9703499, PubMed:10330172, PubMed:10751406, PubMed:11279239, PubMed:12115244, PubMed:12748283, PubMed:15187101, PubMed:15634918, PubMed:17030620, PubMed:16702957, PubMed:20702587, PubMed:20221403, PubMed:21775632, PubMed:27193233, PubMed:23644599, PubMed:25815583. Acts as an 3'-untranslated region, UTR ARE mRNA-binding adapter protein to communicate signaling events to the mRNA decay machinery, PubMed:15687258, PubMed:23644599. Recruits deadenylase CNOT7, and probably the CCR4-NOT complex via association with CNOT1, and hence promotes ARE-mediated mRNA deadenylation, PubMed:23644599. Functions also by recruiting components of the cytoplasmic RNA decay machinery to the bound ARE-containing mRNAs, PubMed:11719186, PubMed:12748283, PubMed:15687258, PubMed:16364915. Self regulates by destabilizing its own mRNA, PubMed:15187101. Binds to 3'-UTR ARE of numerous mRNAs and of its own mRNA, PubMed:10330172, PubMed:10751406, PubMed:12115244, PubMed:15187101, PubMed:15634918, PubMed:17030620, PubMed:16702957, PubMed:19188452, PubMed:20702587, PubMed:20221403, PubMed:21775632, PubMed:25815583. Plays a role in anti-inflammatory responses; suppresses tumor necrosis factor, TNF-alpha production by stimulating ARE-mediated TNF-alpha mRNA decay and several other inflammatory ARE-containing mRNAs in interferon, IFN- and/or lipopolysaccharide, LPS-induced macrophages, By similarity. Plays also a role in the regulation of dendritic cell maturation at the post-transcriptional level, and hence operates as part of a negative feedback loop to limit the inflammatory response, PubMed:18367721. Promotes ARE-mediated mRNA decay of hypoxia-inducible factor HIF1A mRNA during the response of endothelial cells to hypoxia, PubMed:21775632. Positively regulates early adipogenesis of preadipocytes by promoting ARE-mediated mRNA decay of immediate early genes, IEGs, By similarity. Negatively regulates hematopoietic/erythroid cell differentiation by promoting ARE-mediated mRNA decay of the transcription factor STAT5B mRNA, PubMed:20702587. Plays a role in maintaining skeletal muscle satellite cell quiescence by promoting ARE-mediated mRNA decay of the myogenic determination factor MYOD1 mRNA, By similarity. Associates also with and regulates the expression of non-ARE-containing target mRNAs at the post-transcriptional level, such as MHC class I mRNAs, PubMed:18367721. Participates in association with argonaute RISC catalytic components in the ARE-mediated mRNA decay mechanism; assists microRNA, miRNA targeting ARE-containing mRNAs, PubMed:15766526. May also play a role in the regulation of cytoplasmic mRNA decapping; enhances decapping of ARE-containing RNAs, in vitro, PubMed:16364915. Involved in the delivery of target ARE-mRNAs to processing bodies, PBs, PubMed:17369404. In addition to its cytosolic mRNA-decay function, affects nuclear pre-mRNA processing, By similarity. Negatively regulates nuclear poly(A-binding protein PABPN1-stimulated polyadenylation activity on ARE-containing pre-mRNA during LPS-stimulated macrophages, By similarity. Also involved in the regulation of stress granule, SG and P-body, PB formation and fusion, By similarity. Plays a role in the regulation of keratinocyte proliferation, differentiation and apoptosis, PubMed:27182009. Plays a role as a tumor suppressor by inhibiting cell proliferation in breast cancer cells, PubMed:26926077. {ECO:0000250|UniProtKB:P22893, ECO:0000269|PubMed:10330172, ECO:0000269|PubMed:10751406, ECO:0000269|PubMed:11279239, ECO:0000269|PubMed:11719186, ECO:0000269|PubMed:12115244, ECO:0000269|PubMed:12748283, ECO:0000269|PubMed:15187101, ECO:0000269|PubMed:15634918, ECO:0000269|PubMed:15687258, ECO:0000269|PubMed:15766526, ECO:0000269|PubMed:16364915, ECO:0000269|PubMed:16702957, ECO:0000269|PubMed:17030620, ECO:0000269|PubMed:17369404, ECO:0000269|PubMed:18367721, ECO:0000269|PubMed:19188452, ECO:0000269|PubMed:20221403, ECO:0000269|PubMed:20702587, ECO:0000269|PubMed:21775632, ECO:0000269|PubMed:23644599, ECO:0000269|PubMed:25815583, ECO:0000269|PubMed:26926077, ECO:0000269|PubMed:27182009, ECO:0000269|PubMed:27193233, ECO:0000269|PubMed:9703499}.; FUNCTION:, Microbial infection Negatively regulates HTLV-1 TAX-dependent transactivation of viral long terminal repeat, LTR promoter. {ECO:0000269|PubMed:14679154}.
