General annotation (Comments)
| Function | RNA-binding protein implicated in the regulation of several post-transcriptional events. Involved in pre-mRNA alternative splicing, mRNA translation and stability. Mediates exon inclusion and/or exclusion in pre-mRNA that are subject to tissue-specific and developmentally regulated alternative splicing By similarity. Specifically activates exon 5 inclusion of cardiac isoforms of TNNT2 during heart remodeling at the juvenile to adult transition By similarity. Acts as both an activator and repressor of a pair of coregulated exons: promotes inclusion of the smooth muscle (SM) exon but exclusion of the non-muscle (NM) exon in actinin pre-mRNAs By similarity. Activates SM exon 5 inclusion by antagonizing the repressive effect of PTB By similarity. Promotes exclusion of exon 11 of the INSR pre-mRNA By similarity. Inhibits, together with HNRNPH1, insulin receptor (IR) pre-mRNA exon 11 inclusion in myoblast By similarity. Increases translation and controls the choice of translation initiation codon of CEBPB mRNA By similarity. Increases mRNA translation of CEBPB in aging liver. Increases translation of CDKN1A mRNA by antagonizing the repressive effect of CALR3 By similarity. Mediates rapid cytoplasmic mRNA deadenylation By similarity. Recruits the deadenylase PARN to the poly(A) tail of EDEN-containing mRNAs to promote their deadenylation By similarity. Required for completion of spermatogenesis. Binds to (CUG)n triplet repeats in the 3'-UTR of transcripts such as DMPK and to Bruno response elements (BREs) By similarity. Binds to muscle-specific splicing enhancer (MSE) intronic sites flanking the alternative exon 5 of TNNT2 pre-mRNA By similarity. Binds to AU-rich sequences (AREs or EDEN-like) localized in the 3'-UTR of JUN and FOS mRNAs. Binds to the IR RNA By similarity. Binds to the 5'-region of CDKN1A and CEBPB mRNAs By similarity. Binds with the 5'-region of CEBPB mRNA in aging liver. Ref.10 Ref.12 Ref.13 |
| Subunit structure | Associates with polysomes By similarity. Interacts with HNRNPH1; the interaction in RNA-dependent. Interacts with PARN By similarity. Component of an EIF2 complex at least composed of CELF1/CUGBP1, CALR, CALR3, EIF2S1, EIF2S2, HSP90B1 and HSPA5. Ref.12 |
| Subcellular location | Nucleus. Cytoplasm. Note: RNA-binding activity is detected in both nuclear and cytoplasmic compartments By similarity. Ref.11 Ref.12 Ref.13 |
| Tissue specificity | Expressed in skeletal muscle, uterus, diaphragm, lung, spleen, testis, mammary gland, adipose, eye and brain (at protein level). Strongly expressed in aging liver (at protein level). Expressed in lung, stomach, heart to very low levels (at protein level). Expressed in germ cells of the seminiferous tubules except in the central region that contains the elongated spermatids and spermatozoa (at protein level). Expressed in Leydig cells of the interstitial tissue (at protein level). Expressed in the heart, skeletal muscle, testis (from spermatogonia to round spermatids), spleen, lung, neocortex, cerebellar cortex, hippocampus and other areas, abundant in the putamen, and poorly expressed in the thalamus and in the brain stem. Ref.2 Ref.9 Ref.11 Ref.12 Ref.13 |
| Developmental stage | Expressed in heart, muscle, brain, liver, thigh, stomach and lung at 14 dpc (at protein level). Expressed from the two-cell to blastocyst stages. Expressed in tail region, somites, cephalic structures and limb buds at 10.5 dpc. Ref.9 Ref.11 Ref.13 |
| Induction | Its RNA-binding activity on CEBPB mRNA increases in response to EGF. Ref.10 |
| Domain | RRM1 and RRM2 domains preferentially target UGU(U/G)-rich mRNA elements By similarity. |
| Post-translational modification | Phosphorylated. Phosphorylated by CDK4 on Ser-302. Its phosphorylation status increases in aging liver and is important for the formation of the EIF2 complex and activation of CEBPB mRNA translation. Hyperphosphorylated in the EIF2 complex. EGFR signaling regulates its phosphorylation status in epithelial cells. Ref.10 Ref.12 |
| Sequence similarities | Belongs to the CELF/BRUNOL family. Contains 3 RRM (RNA recognition motif) domains. |
| Sequence caution | The sequence CAA43691.1 differs from that shown. Reason: Frameshift at position 367. |
