Vesicular Transport Proteins

Medical Definition: A broad category of proteins involved in the formation, transport and dissolution of TRANSPORT VESICLES. They play a role in the intracellular transport of molecules contained within membrane vesicles. Vesicular transport proteins are distinguished from MEMBRANE TRANSPORT PROTEINS, which move molecules across membranes, by the mode in which the molecules are transported.
Vesicular Transport Proteins Categories.
Canadian Medical Guide Definition Adaptor Proteins - A class of proteins involved in the transport of molecules via TRANSPORT VESICLES. They perform functions such as binding to the cell membrane, capturing cargo molecules and promoting the assembly of CLATHRIN. The majority of adaptor proteins exist as multisubunit complexes, however monomeric varieties have also been found.
Canadian Medical Guide Definition Auxilins - A family of proteins that play a role as cofactors in the process of CLATHRIN recycling in cells.
Canadian Medical Guide Definition Caveolins - The main structural proteins of CAVEOLAE. Several distinct genes for caveolins have been identified.
Canadian Medical Guide Definition Clathrin - The main structural coat protein of COATED VESICLES which play a key role in the intracellular transport between membranous organelles. Each molecule of clathrin consists of three light chains (CLATHRIN LIGHT CHAINS) and three heavy chains (CLATHRIN HEAVY CHAINS) that form a structure called a triskelion. Clathrin also interacts with cytoskeletal proteins.
Canadian Medical Guide Definition Coat Protein Complex I - A protein complex comprised of COATOMER PROTEIN and ADP RIBOSYLATION FACTOR 1. It is involved in transport of vesicles between the ENDOPLASMIC RETICULUM and the GOLGI APPARATUS.
