Clathrin-coated pits是什么
Clathrin is a protein that plays a major role in the formation of coated vesicles. Clathrin was first isolated and named by Barbara Pearse in 1976. It forms a triskelion shape composed of three clathrin heavy chains and three light chains. When the triskelia interact they form a polyhedral lattice that surrounds the vesicle, hence the protein's name, which is derived from the Latin clathrum meaning lattice. Coat-proteins, like clathrin, are used to build small vesicles in order to … WebHere, we demonstrate that both receptor types undergo constitutive endocytosis via clathrin-coated pits (CCPs) but that only BRII undergoes also caveola-like internalization. Using several complementary approaches, we could show that (i) BMP-2-mediated Smad1/5 phosphorylation occurs at the plasma membrane in nonraft regions, (ii) continuation ...

Thereafter, just as in nonsynaptic endocytosis, the clathrin-coated SVs are detached from the PM; the clathrin coat is then disassembled in an ATP-requiring process. The uncoated SVs either rejoin the SV pool in the nerve terminal or are recycled through ... 4款壁纸WebClathrin-coated vesicle maturation incorporates the activities of a range of proteins. Actin, myosin and WASP all have important roles in the formation and stabilization of clathrin-coated pits (CCPs) [1] [2] [3]. Evidence also suggests that F-actin influences the lateral movement of CCPs, which effects the subsequent growth of the vesicle [1]. 4歐姆20w喇叭Clathrin-coated vesicles (CCVs) are found in virtually all cells and form domains of the plasma membrane termed clathrin-coated pits.
