  • 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.
  • 基因功能参考文献：
    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

    14. Hepatitis B virus down-regulated miR-101-3p expression, which resulted in up-regulation of Rap1b, and down-regulation of miR-101-3p or up-regulation of Rap1b promoted proliferation and migration of hepatocellular carcinoma cells PMID: 24697700

    20. RAP1B is prominently expressed in the nucleus of squamous carcinomas. PMID: 13679863
    21. PAR-1 and PAR-4 signal Rap1B activation, the ability of thrombin to activate this GTPase independently of secreted ADP involves costimulation of both receptors as well as binding to GPIb-IX-V. PMID: 15078882
