E. coli biotin ligase
(BirA) is highly specific in covalently attaching biotin to the 15
amino
acid AviTag peptide. This recombinant protein was biotinylated in
vivo
by AviTag-BirA technology, which method is BriA catalyzes amide
linkage
between the biotin and the specific lysine of the AviTag.
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.
產(chǎn)品提供形式:
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.
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(zhì)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.
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.

靶點詳情
功能:
Transcription factor that binds and transactivates the sequence 5'-TAATC[CA]-3' which is found upstream of several photoreceptor-specific genes, including the opsin genes. Acts synergistically with other transcription factors, such as NRL, RORB and RAX, to regulate photoreceptor cell-specific gene transcription. Essential for the maintenance of mammalian photoreceptors.
基因功能參考文獻:
CRX is required for chromatin remodeling at only a subset of its binding sites, which undergo retina or neuronal specific activation during photoreceptor differentiation. PMID: 30068366
proteins involved in phototransduction were not detected in the Crx(-/-) mouse; in this phenotype, however, proteins from spots showing diurnal rhythms were specifically identified as enzymes involved in glucose metabolism, Krebs cycle, and mitochondrial enzymes. PMID: 28371363
The L253X mouse provides a valuable model for CRX-associated retinopathy. The pathogenicity of CRX frameshift mutations depends on the position of the premature termination codon, which in turn determines the degree of mutant mRNA/protein overproduction. PMID: 28903150
CRX-associated retinopathies stem from graded changes in photoreceptor gene expression, which could significantly contribute to phenotypic variability. PMID: 26324254
Rax and Crx cooperatively transactivate Rhodopsin and cone opsin promoters and an optimum Rax expression level to transactivate photoreceptor gene expression exists. PMID: 25986607
E168d2 and R90W are mechanistically distinct mouse models for CRX-associated disease that will allow the elucidation of molecular mechanisms and testing of novel therapeutic approaches for different forms of CRX-associated disease. PMID: 24516401
The rhythmic nature of pineal CRX protein may directly modulate the daily profile of Aanat expression by inducing nighttime expression of this enzyme, facilitating nocturnal melatonin synthesis PMID: 24877634
We conclude that nucleotide changes in evolutionary conserved crx binding site could impact retina-specific expression levels of Kcnv2. PMID: 24664678
In Crx-knockout mice vasopressin mRNA expression in the suprachiasmatic nucleus shows significant daily rhythm. PMID: 23784879
Data have identified a novel retinal SAM domain protein, Samd7, which could act as a transcriptional repressor involved in fine-tuning of Crx-regulated gene expression. PMID: 23565263
Our results show that NRL and CRX together control the expression of most, if not all, genes involved in rod phototransduction through a cis-regulatory module PMID: 22511886
Crx broadly modulates the pineal transcriptome and also influences differential night/day gene expression in this tissue PMID: 21797868
A change in the suprachiasmatic nuclei of the Crx-deficient mouse might explain the observed circadian differences between the knockout mouse and wild-type mouse. PMID: 20438719
CRX combinatorially orchestrates the transcriptional networks of both rods and cones by coordinating the expression of photoreceptor genes including most retinal disease genes. PMID: 20693478
Studies isolated Panky/Ankrd33, a gene encoding an ankyrin repeat-containing protein and that PANKY inhibited the DNA-binding activity of CRX. PMID: 20026326
CRX has a role in retinal and pineal lineage tumors PMID: 19936203
Crx is expressed very soon after a cell fated to be a photoreceptor cell becomes postmitotic. PMID: 19882727
the mouse Crx 5'-upstream genomic sequence is capable of directing a cell-specific and developmentally regulated expression of Crx in photoreceptor cells PMID: 11880494
both Nrl and Crx are required for full transcriptional activity of the PDE6A gene PMID: 15001570
Crx plays an essential role in photoreceptor development and extends our understanding of the pathology of Leber's congenital amaurosis. PMID: 15676071
results indicate that photoreceptor-specific gene transcription is controlled by the combinatorial action of Sp4 and Crx PMID: 15781457
Crx activates opsin transcription by recruiting HAT-containing co-activators and promoting histone acetylation. PMID: 17656371
Crx halted proliferation of retinal stem cells and induced them to differentiate into cells expressing photoreceptor-specific markers PMID: 18172122
