Associates with cytoplasmic CCR4-NOT and PAN2-PAN3 deadenylase complexes to trigger ARE-containing mRNA deadenylation and decay processes (PubMed:20595389, PubMed:21078877). Part of a mRNA decay activation complex at least composed of poly(A)-specific exoribonucleases CNOT6, EXOSC2 and XRN1 and mRNA-decapping enzymes DCP1A and DCP2 (By similarity). Associates with the RNA exosome complex (By similarity). Interacts (via phosphorylated form) with 14-3-3 proteins; these interactions promote exclusion of ZFP36 from cytoplasmic stress granules in response to arsenite treatment in a MAPKAPK2-dependent manner and does not prevent CCR4-NOT deadenylase complex recruitment or ZFP36-induced ARE-containing mRNA deadenylation and decay processes (PubMed:15014438, PubMed:20595389). Interacts with 14-3-3 proteins; these interactions occur in response to rapamycin in an Akt-dependent manner (By similarity). Interacts with AGO2 and AGO4 (By similarity). Interacts (via C-terminus) with CNOT1; this interaction occurs in a RNA-independent manner and induces mRNA deadenylation (PubMed:21278420). Interacts (via N-terminus) with CNOT6 (By similarity). Interacts with CNOT6L (PubMed:21078877). Interacts (via C-terminus) with CNOT7; this interaction occurs in a RNA-independent manner, induces mRNA deadenylation and is inhibited in a phosphorylation MAPKAPK2-dependent manner (PubMed:20595389, PubMed:21278420). Interacts (via unphosphorylated form) with CNOT8; this interaction occurs in a RNA-independent manner and is inhibited in a phosphorylation MAPKAPK2-dependent manner (PubMed:20595389). Interacts with DCP1A (By similarity). Interacts (via N-terminus) with DCP2 (By similarity). Interacts with EDC3 (By similarity). Interacts (via N-terminus) with EXOSC2 (By similarity). Interacts with heat shock 70 kDa proteins (By similarity). Interacts with KHSRP; this interaction increases upon cytokine-induced treatment (By similarity). Interacts with MAP3K4; this interaction enhances the association with SH3KBP1/CIN85 (By similarity). Interacts with MAPKAPK2; this interaction occurs upon skeletal muscle satellite cell activation (PubMed:25815583). Interacts with NCL (By similarity). Interacts with NUP214; this interaction increases upon lipopolysaccharide (LPS) stimulation (By similarity). Interacts with PABPC1; this interaction occurs in a RNA-dependent manner (PubMed:20595389, PubMed:21078877). Interacts (via hypophosphorylated form) with PABPN1 (via RRM domain and C-terminal arginine-rich region); this interaction occurs in the nucleus in a RNA-independent manner, decreases in presence of single-stranded poly(A) RNA-oligomer and in a p38 MAPK-dependent-manner and inhibits nuclear poly(A) tail synthesis (PubMed:22844456). Interacts with PAN2 (PubMed:21078877). Interacts (via C3H1-type zinc finger domains) with PKM (By similarity). Interacts (via C3H1-type zinc finger domains) with nuclear RNA poly(A) polymerase (PubMed:22844456). Interacts with PPP2CA; this interaction occurs in LPS-stimulated cells and induces ZFP36 dephosphorylation, and hence may promote ARE-containing mRNAs decay (PubMed:17170118). Interacts (via C-terminus) with PRR5L (via C-terminus); this interaction may accelerate ZFP36-mediated mRNA decay during stress (By similarity). Interacts (via C-terminus) with SFN; this interaction occurs in a phosphorylation-dependent manner (PubMed:11886850). Interacts (via extreme C-terminal region) with SH3KBP1/CIN85 (via SH3 domains); this interaction enhances MAP3K4-induced phosphorylation of ZFP36 at Ser-58 and Ser-85 and does not alter neither ZFP36 binding to ARE-containing transcripts nor TNF-alpha mRNA decay (By similarity). Interacts with XRN1 (By similarity). Interacts (via C-terminus and Ser-178 phosphorylated form) with YWHAB; this interaction occurs in a p38/MAPKAPK2-dependent manner, increases cytoplasmic localization of ZFP36 and protects ZFP36 from Ser-178 dephosphorylation by serine/threonine phosphatase 2A, and hence may be crucial for stabilizing ARE-containing mRNAs (PubMed:14688255, PubMed:17170118). Interacts (via phosphorylated form) with YWHAE (PubMed:21078877). Interacts (via C-terminus) with YWHAG; this interaction occurs in a phosphorylation-dependent manner (PubMed:11886850). Interacts with YWHAH; this interaction occurs in a phosphorylation-dependent manner (PubMed:11886850). Interacts with YWHAQ; this interaction occurs in a phosphorylation-dependent manner (PubMed:11886850). Interacts with (via C-terminus) YWHAZ; this interaction occurs in a phosphorylation-dependent manner (PubMed:11886850). Does not interact with SH3KBP1 (PubMed:20221403). Interacts (via the 4EHP-binding motif) with EIF4E2; the interaction is direct (By similarity). Interacts (via P-P-P-P-G repeats) with GIGYF2; the interaction is direct (PubMed:26763119).
功能:
Zinc-finger RNA-binding protein that destabilizes numerous 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:10330172, PubMed:10706852, PubMed:10805719, PubMed:15014438, PubMed:15187092, PubMed:15634918, PubMed:17030620, PubMed:19188452, PubMed:20595389, PubMed:21078877, PubMed:22701344, PubMed:27193233). Acts as an 3'-untranslated region (UTR) ARE mRNA-binding adapter protein to communicate signaling events to the mRNA decay machinery (PubMed:21278420). Recruits deadenylase CNOT7 (and probably the CCR4-NOT complex) via association with CNOT1, and hence promotes ARE-mediated mRNA deadenylation (PubMed:21278420). Functions also by recruiting components of the cytoplasmic RNA decay machinery to the bound ARE-containing mRNAs (PubMed:21278420). Self regulates by destabilizing its own mRNA (PubMed:15187092, PubMed:17288565). Binds to 3'-UTR ARE of numerous mRNAs and of its own mRNA (PubMed:11533235, PubMed:15187092, PubMed:16508014, PubMed:17288565, PubMed:17971298, PubMed:20595389, PubMed:21078877, PubMed:21278420, PubMed:22701344, PubMed:27193233). 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 (PubMed:8630730, PubMed:9703499, PubMed:15014438, PubMed:16514065). 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 (By similarity). Promotes ARE-mediated mRNA decay of hypoxia-inducible factor HIF1A mRNA during the response of endothelial cells to hypoxia (By similarity). Positively regulates early adipogenesis of preadipocytes by promoting ARE-mediated mRNA decay of immediate early genes (IEGs) (PubMed:22701344). Negatively regulates hematopoietic/erythroid cell differentiation by promoting ARE-mediated mRNA decay of the transcription factor STAT5B mRNA (By similarity). Plays a role in maintaining skeletal muscle satellite cell quiescence by promoting ARE-mediated mRNA decay of the myogenic determination factor MYOD1 mRNA (PubMed:25815583). Associates also with and regulates the expression of non-ARE-containing target mRNAs at the post-transcriptional level, such as MHC class I mRNAs (By similarity). Participates in association with argonaute RISC catalytic components in the ARE-mediated mRNA decay mechanism; assists microRNA (miRNA) targeting ARE-containing mRNAs (By similarity). May also play a role in the regulation of cytoplasmic mRNA decapping; enhances decapping of ARE-containing RNAs, in vitro (By similarity). Involved in the delivery of target ARE-mRNAs to processing bodies (PBs) (By similarity). In addition to its cytosolic mRNA-decay function, affects nuclear pre-mRNA processing (PubMed:22844456). Negatively regulates nuclear poly(A)-binding protein PABPN1-stimulated polyadenylation activity on ARE-containing pre-mRNA during LPS-stimulated macrophages (PubMed:22844456). Also involved in the regulation of stress granule (SG) and P-body (PB) formation and fusion (PubMed:15967811). Plays a role in the regulation of keratinocyte proliferation, differentiation and apoptosis (By similarity). Plays a role as a tumor suppressor by inhibiting cell proliferation in breast cancer cells.
