... membrane and can regulate a variety of signaling pathways. Caveolins are fundamental components of caveolae, but many cells, such as hepatocytes and many neurons, express caveolins without forming distinguishable caveolae. Thus, the function of caveolins goes beyond their roles as caveolar components...

.... In presence of canonical Wnt ligands PTK7 is subject to caveolin-mediated endocytosis, while it is unaffected by non-canonical Wnt ligands. PTK7 endocytosis is dependent on the presence of the PTK7 co-receptor Fz7 (also known as Fzd7) and results in lysosomal degradation of PTK7. As we previously observed...

Here, we show that RSV morphogenesis occurs within caveolar membranes and that both caveolin-1 and cavin-1 (also known as PTRF), the two major structural and functional...

Integral membrane proteins called caveolins drive the formation of caveolae but the precise mechanisms underlying caveola formation, and the origin of caveolae and caveolins during evolution, are unknown. Systematic evolutionary analysis shows conservation of genes encoding caveolins in metazoans. We...

... in the levels of caveolin-1, -2 and -3. Addition of ·NO-releasing compounds to C2C12 muscle cells reveals that this downregulation of the caveolin (cav) levels is due to the presence of ·NO itself in the case of caveolin-3 and to the action of the LPS/IFN-γ in the case of cav-1 and cav-2. Likewise, muscle cells...
