the receptor protein? the marker protein? Title: what are the different functions of the proteins that are embedded in the lipid bilayer? Post by: BuggerFormic on Aug 5, 2013 channel protein--> transports molecules in & out of cell
receptor protein---> binds signal molecules (such as hormones) and other molecules and virus envelop marker protein.....> tracks molecule Title: what are the different functions of the proteins that are embedded in the lipid bilayer? Post by: mikelowry on Aug 5, 2013 Channel protein: Selectively allows certain molecules/ions to pass through
eg: Aquaporin (allows transport of water molecules) Receptor protein: Selectively recognizes and binds cetain ligands and in turn initiates a cascade of cell signalling events or engulfment of ligand into cell upon recognition eg: Insulin receptor, G-protein coupled receptor Marker protein: It is specific for certain cells and can be used to distinguish from other cell types eg: cancer specific cell markers - VEGF, p53 |
