Calveolin-1 of 178 aas and 2 TMSs.  Caveolae are membrane-budding structures in vertebrate cells, and calveolin-1 forms membrane curvature and endocytic vesicles. Caveolae-like structures can form in E. coli through the expression of caveolin-1.  These caveolae are ~100 nm in diameter and can harbor both animal and bacterial transmembrane proteins (Shin et al. 2015). Molecules from the outside can be taken up into these structures. Transport of fatty acids across the plasma membrane is modulated by caveolin-1 and cholesterol and is not dependent on the putative fatty acid transport proteins, CD36 and FATP (Meshulam et al. 2006).
