Form Liquid or 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 If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
Note: If you have any special requirement for the glycerol content, please remark when you place the order.
If the delivery form is lyophilized powder, the buffer before lyophilization is 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°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
and FAQs
Protein FAQs
Storage Condition Store at -20°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.
Notes Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Data

Function Plays a role in constitutive splicing and can modulate the selection of alternative splice sites. Represses the splicing of MAPT/Tau exon 10.
Gene References into Functions
  1. Dehydroepiandrosterone (DHEA) and cortisol modulate SRSF9 and SRSF3 in a different way and data suggest that the anti-glucocorticoid effect of DHEA, among other mechanisms, is also exerted by modulating the expression of proteins involved in the splicing of the GR pre-mRNA. PMID: 28373129
  2. Report no correlation between expression of glucocorticoid receptor isoforms and SRp30c. PMID: 25665148
  3. Overexpression of SRSF9 and SRSF1 promote beta-catenin accumulation via the recruitment of beta-catenin mRNA and by enhancing its translation in an mTOR-dependent manner. PMID: 23592547
  4. Relative levels of SRp20, SRp30c, and SRp40 in TM cells control differential expression of the two alternatively spliced isoforms of the GR and thereby regulate GC responsiveness. PMID: 22205602
  5. these data indicated that tumor suppressive miR-1 induces apoptosis through direct inhibition of SRSF9 in bladder cancer. PMID: 22178073
  6. These results suggest that SRp30c can activate human papillomavirus type 16 L1 mRNA expression via a bimodal mechanism: directly by stimulating splicing to late splice sites and indirectly by inhibiting competing early splice sites. PMID: 21697349
  7. SRp30c can function as a repressor of 3' splice site utilization and suggest that the SRp30c-CE9 interaction may contribute to the control of hnRNP A1 alternative splicing. PMID: 12024014
  8. SRp30c protein is an interacting protein of YB-1 PMID: 12604611
  9. Serine-arginine-rich protein p30 directs alternative splicing of glucocorticoid receptor pre-mRNA to glucocorticoid receptor beta in neutrophils. PMID: 12738786
  10. Results suggest that bombesin-induced expression of SRp30c affects gllucorticoid receptor (GR) pre-mRNA splicing, leading to increased GR beta expression and contributing to glucocorticoid resistance in PC cells. PMID: 17540466
  11. Study shows that PTB can function as an anti-repressor molecule to counteract the splicing inhibitory activity of SRp30c. PMID: 17548433
  12. SRp30c stimulates splicing to the downstream 5' splice site of Bcl-x(L), thereby attenuating the repressive effect of upstream U1 snRNP binding sit PMID: 18534987
  13. findings indicate the importance of arginine methylation for the subnuclear localization of SFRS9. PMID: 19557313
