Function

RNA-binding protein that is involved in various steps of RNA biogenesis and processing. Preferentially binds, via its two RNA recognition motifs RRM1 and RRM2, to GU-repeats on RNA molecules predominantly localized within long introns and in the 3'UTR of mRNAs. In turn, regulates the splicing of many non-coding and protein-coding RNAs including proteins involved in neuronal survival, as well as mRNAs that encode proteins relevant for neurodegenerative diseases.

Biological Context

Subcellular Location: Nucleus; Cytoplasm; Cytoplasm, Stress granule; Mitochondrion
Tissue Specificity: Ubiquitously expressed. In particular, expression is high in pancreas, placenta, lung, genital tract and spleen
Disease Association: Amyotrophic lateral sclerosis 10 (ALS10) : A neurodegenerative disorder affecting upper motor neurons in the brain and lower motor neurons in the brain stem and spinal cord, resulting in fatal paralysis. Sensory abnormalities are absent. The pathologic hallmarks of the disease include pallor of the corticospinal tract due to loss of motor neurons, presence of ubiquitin-positive inclusions within surviving motor neurons, and deposition of pathologic aggregates. The etiology of amyotrophic lateral sclerosis is likely to be multifactorial, involving both genetic and environmental factors. The disease is inherited in 5-10% of the cases. [The disease is caused by variants affecting the gene represented in this entry. Neurodegeneration is caused by activation of the cGAS-STING pathway: defects in TARDBP trigger mitochondrial DNA release into the cytosol via the permeability transition pore. Released mitochondrial DNA is then detected by CGAS, leading to activation of the cGAS-STING pathway, triggering type-I interferon production and autoinflammation ]

Protein Biology

Function

RNA-binding protein that is involved in various steps of RNA biogenesis and processing (PubMed:23519609). Preferentially binds, via its two RNA recognition motifs RRM1 and RRM2, to GU-repeats on RNA molecules predominantly localized within long introns and in the 3'UTR of mRNAs (PubMed:23519609, PubMed:24240615, PubMed:24464995). In turn, regulates the splicing of many non-coding and protein-coding RNAs including proteins involved in neuronal survival, as well as mRNAs that encode proteins relevant for neurodegenerative diseases (PubMed:21358640, PubMed:29438978). Plays a role in maintaining mitochondrial homeostasis by regulating the processing of mitochondrial transcripts (PubMed:28794432). Also regulates mRNA stability by recruiting CNOT7/CAF1 deadenylase on mRNA 3'UTR leading to poly(A) tail deadenylation and thus shortening (PubMed:30520513). In response to oxidative insult, associates with stalled ribosomes localized to stress granules (SGs) and contributes to cell survival (PubMed:19765185, PubMed:23398327). Also participates in the normal skeletal muscle formation and regeneration, forming cytoplasmic myo-granules and binding mRNAs that encode sarcomeric proteins (PubMed:30464263). Plays a role in the maintenance of the circadian clock periodicity via stabilization of the CRY1 and CRY2 proteins in a FBXL3-dependent manner (PubMed:27123980). Negatively regulates the expression of CDK6 (PubMed:19760257). Regulates the expression of HDAC6, ATG7 and VCP in a PPIA/CYPA-dependent manner (PubMed:25678563)

Subunit

Homodimer (PubMed:20043239, PubMed:24464995). Homooligomer (via its N-terminal domain) (PubMed:28663553, PubMed:29438978). Interacts with BRDT (By similarity). Binds specifically to pyrimidine-rich motifs of TAR DNA and to single stranded TG repeated sequences. Binds to RNA, specifically to UG repeated sequences with a minimum of six contiguous repeats. Interacts with ATXN2; the interaction is RNA-dependent (PubMed:20740007). Interacts with MATR3 (PubMed:24686783). Interacts with UBQLN2 (PubMed:23541532). Interacts with HNRNPA2B1 (PubMed:19429692). Interacts with ZNF106 (By similarity). Interacts with CNOT7/CAF1 (PubMed:30520513). Interacts with CRY2 (PubMed:27123980). Interacts with PPIA/CYPA; the interaction is dependent on RNA-binding activity of TARDBP and PPIase activity of PPIA/CYPA and acetylation of PPIA/CYPA at 'Lys-125' favors the interaction (PubMed:25678563)
