Note: The complete sequence may include tag sequence, target protein sequence, linker sequence and extra sequence that is translated with the protein sequence for the purpose(s) of secretion, stability, solubility, etc.
If the exact amino acid sequence of this recombinant protein is critical to your application, please explicitly request the full and complete sequence of this protein before ordering.
蛋白標簽：

N-terminal 10xHis-tagged and C-terminal Myc-tagged
產品提供形式：

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.
緩沖液：

If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose.
復溶：

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.
儲存條件：

Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
保質期：

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.
貨期：

Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
注意事項：

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

靶點詳情

功能：

Component of the spliceosomal U1 snRNP, which is essential for recognition of the pre-mRNA 5' splice-site and the subsequent assembly of the spliceosome. U1 snRNP is the first snRNP to interact with pre-mRNA. This interaction is required for the subsequent binding of U2 snRNP and the U4/U6/U5 tri-snRNP. SNRPA binds stem loop II of U1 snRNA. In a snRNP-free form (SF-A) may be involved in coupled pre-mRNA splicing and polyadenylation process. May bind preferentially to the 5'-UGCAC-3' motif on RNAs.

1. SNRPA may contribute to GC progression via NGF and could be a prognostic biomarker for GC. PMID: 30039889
2. p65 activation triggered by TCR signaling could promote SNRPA transcription and 3' UTR shortening of STAT5B. Thus we propose that the alternative polyadenylation switching of STAT5B induced by TCR activation is mediated by SNRPA. PMID: 28954886
3. a new mechanism for regulating SMN levels and provides new insight into the roles of U1A in 3' processing of mRNAs. PMID: 24362020
4. An analysis of the kinetic data suggests three phases of U1A-SL2 RNA complex dissociation with time scales of approximately 100 mus, approximately 50 ms, and approximately 2 s. We propose that the first step of dissociation is a fast rearrangement of the complex to form a loosely bound complex. PMID: 21419778
5. structural analysis of U1A protein-stem loop 2 RNA recognition PMID: 21384338
6. study shows that the yellow fever virus (YFV) NS5 protein is able to interact with U1A, a protein involved in splicing and polyadenylation; a region between amino acids 368 and 448 was identified as the site of interaction of the NS5 protein with U1A PMID: 21298455
