Target Background

May act as a scaffolding protein within caveolar membranes. Interacts directly with G-protein alpha subunits and can functionally regulate their activity. Acts as an accessory protein in conjunction with CAV1 in targeting to lipid rafts and driving caveolae formation. The Ser-36 phosphorylated form has a role in modulating mitosis in endothelial cells. Positive regulator of cellular mitogenesis of the MAPK signaling pathway. Required for the insulin-stimulated nuclear translocation and activation of MAPK1 and STAT3, and the subsequent regulation of cell cycle progression.
Gene References into Functions
  1. Cav-2beta isoform yielded by alternative translation initiation desensitizes insulin receptor (IR) via dephosphorylation by PTP1B, and subsequent endocytosis and lysosomal degradation of IR, causing insulin resistance. PMID: 29604334
  2. Results verified the presence of transcript III of cav-2 for the first time, but no protein associated was found. Also, a decreasing trend of cav-2 (transcripts I and II) were observed in tumoral tissues especially in stages I and II and seem to be associated with the incidence and promotion of breast cancer, especially in the initial stages of breast cancer. PMID: 28857238
  3. High CAV2 expression is associated with lung cancer. PMID: 26930711
  4. A-type lamin-dependent Caveolin-2 homo-oligomerization in the inner nuclear membrane microdomain is a precondition for pY19-Caveolin-2-mediated insulin-response epigenetic activation at the nuclear periphery. PMID: 27552914
  5. Caveolin-2 expression is necessary for the control of E2-dependent cellular proliferation of MCF-7 cells. PMID: 26480297
  6. variant in CAV2 is associated with increased age-of-onset of P. aeruginosa airway infection in cystic fibrosis cohort. PMID: 26047157
  7. Results present initial characterization of key proteins Cav2 and CFL1 as cellular factors that colocalize with M in viral inclusions and filaments and ZNF502 protein which appears to interact with RSV M in the nucleus. PMID: 25556234
  8. Our findings did not correspond with previous positive results, suggesting that CAV1-CAV2 variants studied in the present study are not important risk factors for Normal Tension Glaucoma. PMID: 23743525
  9. This study does not support an association between CAV2 variation and kidney transplant survival. PMID: 23667606
  10. The combination of the expression of the genes for PPARgamma, STMN1 and CAV2 was significantly predictive for early recurrence of non-muscle-invasive bladder cancer PMID: 21489836
  11. In contrast to wild-type-Cav-2, retroviral re-expression of Y19/27F-Cav-2 in Cav-2 knockout endothelial cells did not affect anti-proliferative effect of TGF-beta compared to empty vector. PMID: 22819829
  12. Stromal caveolin-2 expression were more frequent in anaplastic carcinoma and diffuse sclerosing variant of papillary carcinoma compared to conventional papillary thyroid carcinoma. PMID: 22236542
  13. CAV1 mRNA and protein levels are reduced by both NFBD1 knockdown and knockout independently of IR and p53 PMID: 21551225
  14. cav-2 acts as a modulator of cancer progression. PMID: 21373752
  15. We found preliminary evidence that CAV2 rs2270188 interacts with dietary fat to affect risk of type 2 diabetes. PMID: 21178094
  16. Single Nucleotide Polymorphisms in CAV2 is associated with primary open-angle glaucoma. PMID: 20835238
  17. In Caco-2 cells, a polarized cell line derived from human colon cancer that does not express caveolin 1 (Cav-1), there was no detectable expression of caveolin 2 (Cav-2). PMID: 12414992
  18. caveolin-2 may play a role in lamellar granule assembly, trafficking, and/or function. PMID: 12648214
  19. PPARgamma ligands increased the levels of caveolin-2 2-5-fold in a concentration-dependent manner within 24 h. Nonthiazolidinedione PPARgamma ligands elevated caveolin-2 protein 3-4-fold. PMID: 12813462
  20. New evidence demonstrating that Cav-2 undergoes phosphorylation at both tyrosines 19 and 27 also reveals that tyrosine phosphorylation of Cav-2 has no effect on its targeting to lipid rafts, but clearly disrupts hetero-oligomerization of Cav-2 with Cav-1. PMID: 15504032
  21. Heterologously and endogenously expressed D1 dopamine receptors in renal cells are associated with and regulated by caveolin-2. PMID: 15569306
  22. Overexpression of caveolin-2 is associated with inflammatory breast cancer PMID: 16244790

  25. CAV2 is preferentially expressed in basal-like cancers and is associated with poor prognosis PMID: 17912630
  26. Data suggests a possible involvement of serine 36-phosphorylated caveolin-2 in modulating mitosis. PMID: 18081315
