Associates with cytoplasmic CCR4-NOT and PAN2-PAN3 deadenylase complexes to trigger ARE-containing mRNA deadenylation and decay processes. 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. Associates with the RNA exosome complex. 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. Interacts with 14-3-3 proteins; these interactions occur in response to rapamycin in an Akt-dependent manner. Interacts with AGO2 and AGO4. Interacts (via C-terminus) with CNOT1; this interaction occurs in a RNA-independent manner and induces mRNA deadenylation. Interacts (via N-terminus) with CNOT6. Interacts with CNOT6L. 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. Interacts (via unphosphorylated form) with CNOT8; this interaction occurs in a RNA-independent manner and is inhibited in a phosphorylation MAPKAPK2-dependent manner. Interacts with DCP1A. Interacts (via N-terminus) with DCP2. Interacts with EDC3. Interacts (via N-terminus) with EXOSC2. Interacts with heat shock 70 kDa proteins. Interacts with KHSRP; this interaction increases upon cytokine-induced treatment. Interacts with MAP3K4; this interaction enhances the association with SH3KBP1/CIN85. Interacts with MAPKAPK2; this interaction occurs upon skeletal muscle satellite cell activation. Interacts with NCL. Interacts with NUP214; this interaction increases upon lipopolysaccharide (LPS) stimulation. Interacts with PABPC1; this interaction occurs in a RNA-dependent manner. 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. Interacts with PAN2. Interacts (via C3H1-type zinc finger domains) with PKM. Interacts (via C3H1-type zinc finger domains) with nuclear RNA poly(A) polymerase. Interacts with PPP2CA; this interaction occurs in LPS-stimulated cells and induces ZFP36 dephosphorylation, and hence may promote ARE-containing mRNAs decay. Interacts (via C-terminus) with PRR5L (via C-terminus); this interaction may accelerate ZFP36-mediated mRNA decay during stress. Interacts (via C-terminus) with SFN; this interaction occurs in a phosphorylation-dependent manner. Interacts (via extreme C-terminal region) with SH3KBP1/CIN85 (via SH3 domains); this interaction enhances MAP3K4-induced phosphorylation of ZFP36 at Ser-64 and Ser-91 and does not alter neither ZFP36 binding to ARE-containing transcripts nor TNF-alpha mRNA decay. Interacts with XRN1. Interacts (via C-terminus and Ser-184 phosphorylated form) with YWHAB; this interaction occurs in a p38/MAPKAPK2-dependent manner, increases cytoplasmic localization of ZFP36 and protects ZFP36 from Ser-184 dephosphorylation by serine/threonine phosphatase 2A, and hence may be crucial for stabilizing ARE-containing mRNAs. Interacts (via phosphorylated form) with YWHAE. Interacts (via C-terminus) with YWHAG; this interaction occurs in a phosphorylation-dependent manner. Interacts with YWHAH; this interaction occurs in a phosphorylation-dependent manner. Interacts with YWHAQ; this interaction occurs in a phosphorylation-dependent manner. Interacts with (via C-terminus) YWHAZ; this interaction occurs in a phosphorylation-dependent manner. Does not interact with SH3KBP1. Interacts (via P-P-P-P-G repeats) with GIGYF2; the interaction is direct.
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. Acts as an 3'-untranslated region (UTR) ARE mRNA-binding adapter protein to communicate signaling events to the mRNA decay machinery. Recruits deadenylase CNOT7 (and probably the CCR4-NOT complex) via association with CNOT1, and hence promotes ARE-mediated mRNA deadenylation. Functions also by recruiting components of the cytoplasmic RNA decay machinery to the bound ARE-containing mRNAs. Self regulates by destabilizing its own mRNA. Binds to 3'-UTR ARE of numerous mRNAs. Binds also to ARE of its own mRNA. 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. 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. Promotes ARE-mediated mRNA decay of hypoxia-inducible factor HIF1A mRNA during the response of endothelial cells to hypoxia. Positively regulates early adipogenesis of preadipocytes by promoting ARE-mediated mRNA decay of immediate early genes (IEGs). Negatively regulates hematopoietic/erythroid cell differentiation by promoting ARE-mediated mRNA decay of the transcription factor STAT5B mRNA. Plays a role in maintaining skeletal muscle satellite cell quiescence by promoting ARE-mediated mRNA decay of the myogenic determination factor MYOD1 mRNA. Associates also with and regulates the expression of non-ARE-containing target mRNAs at the post-transcriptional level, such as MHC class I mRNAs. Participates in association with argonaute RISC catalytic components in the ARE-mediated mRNA decay mechanism; assists microRNA (miRNA) targeting ARE-containing mRNAs. May also play a role in the regulation of cytoplasmic mRNA decapping; enhances decapping of ARE-containing RNAs, in vitro. Involved in the delivery of target ARE-mRNAs to processing bodies (PBs). In addition to its cytosolic mRNA-decay function, affects nuclear pre-mRNA processing. Negatively regulates nuclear poly(A)-binding protein PABPN1-stimulated polyadenylation activity on ARE-containing pre-mRNA during LPS-stimulated macrophages. Also involved in the regulation of stress granule (SG) and P-body (PB) formation and fusion. Plays a role in the regulation of keratinocyte proliferation, differentiation and apoptosis. Plays a role as a tumor suppressor by inhibiting cell proliferation in breast cancer cells.
