Crystal Structure of the Vesicular Transport Protein Sec17

A vesicular transport protein, or vesicular transporter, is a

membrane protein Membrane proteins are common proteins that are part of, or interact with, biological membranes. Membrane proteins fall into several broad categories depending on their location. Integral membrane proteins are a permanent part of a cell membrane ...

that regulates or facilitates the movement of specific molecules across a vesicle's

membrane A membrane is a selective barrier; it allows some things to pass through but stops others. Such things may be molecules, ions, or other small particles. Membranes can be generally classified into synthetic membranes and biological membranes. ...

. As a result, vesicular transporters govern the concentration of molecules within a vesicle.

Archain Archain is a human protein ithat is encoded by gene which is locatedd on chromosome 11. Also known as ARCN1, it plays a role in eukaryotic cell biology. It is part of the COPI coatomer The coatomer is a protein complex that coats membrane-boun ...

Clathrin 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. Wh ...

Caveolin In molecular biology, caveolins are a family of integral membrane proteins that are the principal components of caveolae membranes and involved in receptor-independent endocytosis. Caveolins may act as scaffolding proteins within caveolar me ...

Dynamin Dynamin is a GTPase responsible for endocytosis in the eukaryotic cell. Dynamin is part of the " dynamin superfamily", which includes classical dynamins, dynamin-like proteins, Mx proteins, OPA1, mitofusins, and GBPs. Members of the dynamin ...
