  1. Transport protein

    A transport protein variously referrred to as a transmembrane pump , transporter protein , escort protein , fatty acid transport protein , cation transport protein , or anion transport protein is a protein which serves the function of moving other materials within an organism . Transport proteins are vital to the growth and life of all living things. There are several different kinds of transport proteins. Carrier protein s are proteins involved in the movement of ions , small molecules , or macromolecules , such as another protein, across a biological membrane. ref Sadava, David, et al. Life, the Science of Biology, 9th Edition. Macmillan Publishers, 2009. ISBN 1429219629. pg 119. ref Carrier proteins are integral membrane proteins that is they exist within and span the membrane across which they transport substances. The proteins may assist in the movement of substances by facilitated diffusion or active transport . These mechanisms of movement are known as carrier mediated transport . ref Thompson, Liz A.

    Vesicle associated membrane proteins VAMP are a family of SNARE protein SNARE proteins with similar structure, and are mostly involved in vesicle fusion . VAMP1 and VAMP2 proteins known as synaptobrevin s are expressed in brain and are constituents of the synaptic vesicles, where they participate in exocytosis neuromediator release . VAMP3 known as cellubrevin is ubiquitously expressed and participates in regulated and constitutive exocytosis as a constituent of secretory granules and secretory vesicles. VAMP5 and VAMP7 SYBL1 participate in constitutive exocytosis. VAMP5 is a constituent of secretory vesicles, myotubes and tubulovesicular structures. VAMP7 is found both in secretory granules and endosomes. VAMP8 known as endobrevin participates in endocytosis and is found in early endosomes.
