Tag Info
Tag type will be determined during the manufacturing process.
The tag type will be determined during production process. If you have specified tag type, please tell us and we will develop the specified tag preferentially.
Lyophilized powder
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
Buffer before Lyophilization
Tris/PBS-based buffer, 6% Trehalose, pH 8.0
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Troubleshooting and FAQs
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Lead Time
Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Participates in antiviral signaling. Acts as a negative regulator of MAVS-mediated antiviral responses, through the inhibition of the virus-induced RLH (RIG-like helicase)-MAVS interaction. Instead, promotes autophagy by interacting with TUFM and subsequently recruiting the autophagy-related proteins ATG5 and ATG12. Regulates also MAVS-dependent NLRP3 inflammasome activation to attenuate apoptosis. Has no inhibitory function on NF-kappa-B signaling pathway, but enhances NF-kappa-B and JUN N-terminal kinase dependent signaling through the production of reactive oxygen species.
Gene References into Functions
  1. Data show that NLRX1 specifically interacts with FASTKD5 and colocalizes with mitochondrial RNA granules. Further results suggest an important role of NLRX1 in regulating the post-transcriptional processing of mitochondrial RNA, which may have an important implication in bioenergetic adaptation during metabolic stress, oncogenic transformation and innate immunity. PMID: 29932989
  2. genetic association studies in Han population in southern China: Data suggest that, in subjects with type 2 diabetes, an SNP in NLRX1 (rs4245191) is associated with macro-vascular complications and cerebral infarction in the population studied; no such association was found for two other SNPs in NLRX1 (rs10790286, rs561830) or for two SNPs in TRAF6 (rs5030445, rs16928973). (TRAF6 = TNF receptor associated factor-6) PMID: 29046236
  3. Data show that NLRX1 suppresses tumorigenesis and reveals new genetic pathways involved in the pathobiology of histiocytic sarcoma. PMID: 27105514
  4. NLRX1 exerted opposing regulatory effects on viral activation of the transcription factors IRF1 and IRF3. NLRX1 suppressed MAVS-mediated activation of IRF3, it conversely facilitated virus-induced increases in IRF1 expression and thereby enhanced control of viral infection. PMID: 28967880
  5. downregulated in brain injury following aneurysm PMID: 28993512
  6. The data suggests that NLRX1 plays a positive role in Kaposi's sarcoma-associated herpesvirus (KSHV) lytic replication by suppressing the IFNbeta response during the process of KSHV reactivation, which might serve as a potential target for restricting KSHV replication and transmission. PMID: 28459883
  7. we identify a novel signaling hub centering on the NLRX1 TUFM protein complex, promoting autophagic flux. Defects in the expression of either NLRX1 or TUFM result in compromised autophagy when treated with EGFR inhibitors.These findings expand our understanding of the components involved in head and neck squamous cell carcinoma autophagy machinery that responds to EGFR inhibitors. PMID: 26876213
  8. findings suggest that NLRX1 may function as a cardiac-protective molecule in myocardial ischemic injury by repressing inflammation and apoptosis PMID: 27393910
  9. NLRX1, NLRP12 and NLRC3 negatively modulate the host immune response following virus exposure. (Review) PMID: 26763980
  10. NLRX1 acts as a potential tumor suppressor by regulating the TNF-alpha induced cell death and metabolism. PMID: 25639646
  11. These data support a model in which CS-dependent NLRX1 inhibition facilitates MAVS/RHL activation and subsequent inflammation, remodeling, protease, cell death, and inflammasome responses. PMID: 25938787
  12. Together, these results suggest a novel mechanism for rhinovirus-induced epithelial barrier disruption involving NLRX-1 and mitochondrial reactive oxygen species generation. PMID: 24429360
  13. NLRX1 and TUFM work in concert to reduce cytokine response and augment autophagy. PMID: 23321557
  14. Results showed that missense mutations in transmembrane protein 2 p.Ser1254Asn, interferon alpha 2 p.Ala120Thr, its regulator NLR family member X1 p.Arg707Cys, and complement component 2 p.Glu318Asp were associated with chronic hepatitis B. PMID: 22610944
  15. Post-transcriptional inhibition of luciferase reporter assays by the Nod-like receptor proteins NLRX1 and NLRC3. PMID: 22718770
  16. NLRX1 attenuated IFN-I production & promoted autophagy during viral infection cells. NLRX1 interacts with TUFM. PMID: 22749352
  17. NLRX1 interacts directly with RNA and suggestts a role for NLRX1 in recognition of intracellular viral RNA in antiviral immunity. PMID: 22386589
  18. the presence of NLRX1 is required for optimal chlamydial growth and reactive oxygen species production PMID: 20959452
  19. function of NOD-like receptors in the antiviral response [REVIEW] PMID: 18466630
  20. identification of NLRX1 as a check against mitochondrial antiviral responses--an intersection of three ancient cellular processes: NLR signalling, intracellular virus detection and the use of mitochondria as a platform for anti-pathogen signalling PMID: 18200010
  21. These results identify NLRX1 as a NLR that contributes to the link between reactive oxygen species generation at the mitochondria and innate immune responses. PMID: 18219313
  22. sequesters MAVS away from RIG-I and thereby prevents mitochondrial anti-viral immunity PMID: 18397740
  23. NLRX1 has a functional leader sequence and fully translocates to the mitochondrial matrix. PMID: 19692591
