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.

靶點詳情

功能：

GTP-binding protein that possesses intrinsic GTPase activity. Contributes to the polarizing activity of KRIT1 and CDH5 in the establishment and maintenance of correct endothelial cell polarity and vascular lumen. Required for the localization of phosphorylated PRKCZ, PARD3 and TIAM1 to the cell junction. Plays a role in the establishment of basal endothelial barrier function.
基因功能參考文獻：
1. Talin-F0 domain binds to Rap1b like canonical Rap1 effectors despite little sequence homology, and disruption of the binding strongly impairs integrin activation, cell adhesion, and cell spreading. PMID: 29170462
2. Aberrant expression of lncRNA AFAP1-AS, a competing endogenous RNA of miR-181a, may involve in the onset and progression of Hirschsprung disease by augmenting the miR-181a target gene, RAP1B. PMID: 28924375
3. In RCC tissues and renal carcinoma cells, miR-28-5p is expressed at a low level and RAP1B is expressed at a high level. miR-28-5p inhibits the tumorigenesis of RCC by directly downregulating RAP1B and influencing the activation of two MAP kinases in the MAPK signaling pathway, p38 and Erk1/2. PMID: 27729617
4. describe the methods for expression and purification of the plexin cytoplasmic region in E. coli, and characterization of its GAP activity using a photometric assay. We also provide a protocol for measuring GAP activity of single-chain constructs with Rap covalently linked to the plexin cytoplasmic region PMID: 27787845
5. Data show that RAP1B expression was up-regulated in esophageal squamous cell carcinoma (ESCC) clinical samples and RAP1B interacted with DVL2 and activated Wnt/beta-catenin signaling. PMID: 28119087
6. The protein expression of RAP1B and HIF-1 alpha contributed to gastric cancer malignant behavior and poor prognosis. PMID: 26329876
7. Cholera toxin and beta-adrenergic receptor activation phosphorylate Rap1B and inhibit its prenylation and membrane localization. PMID: 26209110
8. Glucocorticoids mediate induction of microRNA-708 to suppress ovarian cancer metastasis through targeting Rap1B. PMID: 25569036
9. Adenosine signaling reduces prenylation and plasma membrane localization of Rap1B, resulting in enhanced tumor cell scattering and invasiveness. PMID: 23716715
10. High concentrations of extracellular adenosine in the tumor microenvironment can chronically activate A2B receptors to suppress Rap1B prenylation and signaling at the cell membrane, resulting in reduced cell-cell contact and promoting cell scattering. PMID: 23716716
11. TMZ as a standard chemotherapeutic agent for GBM inhibits the Rap1B expression and actin cytoskeleton remodeling to exert its cell killing by upregulating miR-181a/b/c/d subunits PMID: 24573637

20. RAP1B is prominently expressed in the nucleus of squamous carcinomas. PMID: 13679863
