Webb10 apr. 2024 · The Saccharomyces cerevisiae Agp2 is a plasma membrane protein initially reported to be an uptake transporter for L-carnitine. Agp2 was later rediscovered, together with three additional proteins, Sky1, Ptk2, and Brp1, to be involved in the uptake of the polyamine analogue bleomycin-A5, an anticancer drug.

Webb17 maj 2024 · The cell membrane has many proteins, as well as other lipids (such as cholesterol), that are associated with the phospholipid bilayer. An important feature of the membrane is that it remains fluid; the lipids and proteins in the cell membrane are not rigidly locked in place. Figure \(\PageIndex{2}\): Phospholipid Bilayer. WebbRas proteins are synthesized as cytosolic precursors, but then undergo posttranslational lipid addition, membrane association, and subcellular targeting to the plasma …
