Avi-tag Biotinylated
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.
產品提供形式：

Lyophilized powder Warning: in_array() expects parameter 2 to be array, null given in /www/web/cusabio_cn/public_html/caches/caches_template/default/content/show_product_protein.php on line 662
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：

Guanine nucleotide exchange factor (GEF) for RAP1A, RAP1B and RAP2A small GTPases that is activated by binding cAMP. Seems not to activate RAB3A. Involved in cAMP-dependent, PKA-independent exocytosis through interaction with RIMS2.

1. Study identifies Epac2-Rap1 signaling as a novel feedback mechanism in the heart, which controls mitochondrial reactive oxygen species production. PMID: 27649969
2. rs17746510, one of the three single-nucleotide polymorphisms (SNPs) in RAPGEF4 associated with cognitive decline in Chinese Alzheimer's disease (AD) patients, was significantly correlated with apathy and mood disturbance PMID: 27598965
3. Data show that Epac2 is activated by cAMP and changes its structure. It is involved in cAMP-mediated signal transduction through activation of the Ras-like small GTPase and is expressed mainly in brain, neuroendocrine and endocrine tissues. [review] PMID: 26390815

8. An important time-limited role is identified for hippocampal Epac2 signaling in cognition, opening new avenues to investigate the molecular mechanisms underlying memory retrieval. PMID: 19739231
9. Epac2 & Epac1 signaling pathways may be associated with cAMP-mediated functional differentiation and syncytialization of trophoblasts. Expression of Epac2 & Epac 1 in placenta at different stages was investigated. PMID: 20663796
10. Studies demonstrate the occurrence of the EPAC2 splicing variant EPAC2B in adrenocortical cancer cells and reveal the involvement of EPAC2B in cAMP-induced effects on cytoskeleton integrity and cell migration. PMID: 20233795
11. Mutations in the hinge of Epac can uncouple cAMP binding from its exchange activity. PMID: 12469113
12. variants were present in five families, where they segregate with the autistic phenotype. PMID: 14593429
13. Epac2 signaling plays a stimulatory role in pancreatic and intestinal endocrine cells, including proglucagon transcription and glucagon and GLP-1 production. PMID: 18854429
14. Substitution of the conserved phenylalanine 435 with glycine facilitates the hinge bending and leads to a constitutively active Epac2 capable of stimulating nucleotide exchange in the absence of cAMP. PMID: 19553663
