Background

Function：Involved in the 3'-end formation of mRNA precursors (pre-mRNA) by the addition of a poly(A) tail of 200-250 nt to the upstream cleavage product (By similarity). Stimulates poly(A) polymerase (PAPOLA) conferring processivity on the poly(A) tail elongation reaction and also controls the poly(A) tail length (By similarity). Increases the affinity of poly(A) polymerase for RNA (By similarity). Is also present at various stages of mRNA metabolism including nucleocytoplasmic trafficking and nonsense-mediated decay (NMD) of mRNA. Cooperates with SKIP to synergistically activate E-box-mediated transcription through MYOD1 and may regulate the expression of muscle-specific genes (PubMed:11371506). Binds to poly(A) and to poly(G) with high affinity (By similarity). May protect the poly(A) tail from degradation (By similarity). Subunit of the trimeric poly(A) tail exosome targeting (PAXT) complex, a complex that directs a subset of long and polyadenylated poly(A) RNAs for exosomal degradation. The RNA exosome is fundamental for the degradation of RNA in eukaryotic nuclei. Substrate targeting is facilitated by its cofactor MTREX, which links to RNA-binding protein adapters (PubMed:27871484)

Subcellular Localization：Nucleus; Cytoplasm; Nucleus speckle

Expression：
Tissue_specificity:Ubiquitous

Isoforms & Post-Translational Modification：Q86U42 has 3 isomers: Q86U42-1: 32749 Da (predicted); Q86U42-2: 31497 Da (predicted); Q92843-2: 37171 Da (predicted).
Arginine dimethylation is asymmetric and involves PRMT1 and PRMT3. It does not influence the RNA binding properties (By similarity)

Subunit：May interact with SETX (PubMed:21700224). Monomer and homooligomer. Binds RNA as a monomer and oligomerizes when bound to poly(A). Interacts with PAPOLA, but only in presence of oligo(A) RNA. Interacts with transportin. Identified in a IGF2BP1-dependent mRNP granule complex containing untranslated mRNAs. Association in a ternary complex with CPSF4 and influenza A virus NS1 blocks pre-mRNAs processing, thereby preventing nuclear export of host cell mRNAs. Associates in a single complex with SKIP and MYOD1 and interacts with SKIP in differentiated myocytes. Interacts with NUDT21/CPSF5. Interacts (via RRM domain and C-terminal arginine-rich region) with ZFP36 (via hypophosphorylated form); 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-dependent-manner and may down-regulated RNA poly(A) polymerase activity (By similarity). Component of the poly(A) tail exosome targeting (PAXT) complex made of accessory factors, such as PABPN1, ZFC3H1 and MTREX (PubMed:27871484). Interacts with ZFC3H1 in a RNase-insensitive manner (PubMed:27871484). Interacts with FRG1 (PubMed:17103222). Interacts with ZC3H11A (PubMed:37356722)
