Human Matrin-3(MATR3) ELISA kit

May play a role in transcription or may interact with other nuclear matrix proteins to form the internal fibrogranular network. In association with the SFPQ-NONO heteromer may play a role in nuclear retention of defective RNAs. Plays a role in the regulation of DNA virus-mediated innate immune response by assembling into the HDP-RNP complex, a complex that serves as a platform for IRF3 phosphorylation and subsequent innate immune response activation through the cGAS-STING pathway. May bind to specific miRNA hairpins.

1. Depletion of SAFB1 reduced FUS's localization to chromatin-bound fraction and splicing activity, suggesting SAFB1 could tether FUS to chromatin compartment thorough N-terminal DNA-binding motif. Moreover, FUS interacts with another nuclear matrix-associated protein, Matrin3. PMID: 27731383
2. Using a novel RNA pulldown approach that utilized endogenous S1-tagged PINCR (a p53-regulated long noncoding RNA), the authors show that PINCR associates with the enhancer region of these genes by binding to RNA-binding protein Matrin 3 that, in turn, associates with p53. PMID: 28580901
3. Matrin3 physically interacts with intronic pyrimidine-rich sequences and controls alternative splicing. PMID: 28695676

5. Its mutations strengthens the role of RNA metabolism in amyotrophic lateral sclerosis etiology. PMID: 26493020
6. A missense mutation in MATR3 was identified in myopathy patients undergoing a needle electromyography. PMID: 26899464
7. Our findings indicate that mutations in Matrin 3 that are associated with ALS and myopathy do not dramatically alter the normal localization of the protein or readily induce inclusion formation. PMID: 26528920
8. Three-dimensional mapping of the lamin A-matrin-3 interface showed that the LMNA truncating mutation Delta303, which lacks the matrin-3 binding domain, was associated with an increased distance between lamin A and matrin-3. PMID: 25948554
9. Suppressing Matrin 3 powers a heightened and broader ZAP restriction of HIV-1 gene expression. PMID: 26129669
10. MATR3 mutation is identified to be a possible cause of amyotrophic lateral sclerosis. PMID: 25771394
11. No mutations were identified, indicating that MATR3 mutations are not a common cause of Amyotrophic lateral sclerosis in Australian familial cases with predominately European ancestry PMID: 25523636
12. MATR3 gene disruption is associated with bicuspid aortic valve, aortic coarctation and patent ductus arteriosus. PMID: 25574029
13. Mutations in MATR3 are rare in French familial ALS and ALS with FTLD patients. PMID: 25158920
14. This study shows a high risk of abnormal respiratory function with progressive worsening in MATR3 myopathy. PMID: 25677933
15. Nuclear matrix protein Matrin3 regulates alternative splicing and forms overlapping regulatory networks with PTB. PMID: 25599992
16. the pY RNA1-s2/Matr3 interaction could play a role in vision PMID: 24558381
17. Sixteen patients from 6 families with late onset distal myopathy associated with the p.S85C MATR3 mutation were characterized. PMID: 25154462
18. This study identified mutations in MATR3 in ALS kindreds. also observed MATR3 pathology in ALS-affected spinal cords with and without MATR3 mutations. PMID: 24686783
19. Data suggest that the cellular level of MATR3, known to be highly regulated, modulates the stability of a group of gene transcripts. PMID: 21858232
20. Rev needs MATR3 to promote the cytoplasmic accumulation and translation of unspliced RRE-containing mRNA. PMID: 21771348
21. MATR3 binds viral RNA and is required for the Rev/RRE mediated nuclear export of unspliced HIV-1 RNAs. PMID: 21771346
22. Matrin 3 binds Rev RNA to stabilize HIV-1 transcripts leading to increased cytoplasmic expression. PMID: 21771347
23. MATR3 to be a novel ATM target in response to DNA damage. PMID: 20421735
24. matrin 3 plays a significant role in controlling cell growth and proliferation PMID: 21182838
25. study of the association of matr3 with chromosome territories and identification of potential interacting proteins PMID: 19562669
26. Data show that the nuclear matrix protein matrin 3, cytoskeletal motor protein HMP, and the circadian clock protein lark were significantly decreased in fetal Down syndrome brain. PMID: 12469345
27. These results suggest that the functions of matrin 3 could be regulated by both Ca(2+)-dependent interaction with calmodulin and caspase-mediated cleavage. PMID: 17658460
