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.
Form
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
Reconstitution
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.
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Function
Receptor for RNL3/relaxin-3. Binding of the ligand inhibit cAMP accumulation.
Gene References into Functions
  1. This study indicated that RXFP3 mainly localised in the post-acrosomal region of sperm head and neck. PMID: 29159832
  2. The role of these four INSL5 determinants in distinguishing RXFP4 from RXFP3. PMID: 27404393
  3. Therefore, we conclude that stapling of the relaxin3 B chain does not compromise its ability to activate RXFP3 and is a promising method for developing stable peptide agonists and antagonists of RXFP3 to aid relaxin-3/RXFP3 research. PMID: 27498038
  4. the negatively charged transmembrane aspartate residue controls activation of the relaxin-3 receptor RXFP3 PMID: 27353281
  5. we demonstrated distinct patterns of signalling for H3 and H2 relaxin and R3(BDelta23-27)R/I5 at the RXFP3 receptor PMID: 24641548
  6. Glu141 and Asp145 of the RXFP3 interact with the highly conserved arginine residues of relaxin-3. PMID: 24615237
  7. demonstrate the existence of an allosteric site for modulation of RXFP3 PMID: 22347403
  8. H3 relaxin potently activates all signaling pathways coupled to RXFP3, whereas H2 relaxin is an AP-1-biased ligand relative to H3 relaxin. PMID: 20159943
  9. GPCR135 (SALPR) is the receptor for relaxin-3 PMID: 14522968
  10. Substitution of the relaxin-3 A-chain with the A-chain from insulin-like peptide 5 results in a chimeric peptide that selectively activates GPCR135 and GPCR142. PMID: 15465925
  11. functional response to H3 relaxin and other relaxin/insulin peptides of GPCR135 expressed in CHO-K1 cells was measured in the cytosensor microphysiometer and analyzed using inhibitors of signal transduction proteins PMID: 15956730
  12. analysis of truncated human relaxin-2 and -3 (H2 and H3) relaxin peptides and their binding and cAMP activities on RXFP1, RXFP2, and RXFP3 PMID: 18434306
  13. the N-terminus and EL2 domains of RXFP3 and RXFP4 are involved in ligand binding while TM2, 3, and 5 are critical for receptor activation. PMID: 18582868
  14. Results decribe the structural and functional aspects of the interaction between relaxin-3 and its receptor, RXFP3. PMID: 19152634
