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 GST-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. 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.
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:
Basically, we can dispatch the products out in 1-3 working days
after receiving your orders. 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.
注意事項:
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
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.

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

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
