transmembrane protein

(Science: cell biology) A protein subunit in which the polypeptide chain is exposed on both sides of the membrane. The term does not apply when different subunits of protein complex are exposed at opposite surfaces. most integral membrane proteins are also transmembrane proteins.

Collect the cytoplasmic loop segments from 7TM receptors

... My project objective is to find out whether cytoplasmic loops of '7-transmembrane helix' receptor proteins show structural homology/conserved features. I have chosen Class C (or 3) Metabotropic ...

Do we know all the proteins (and their primary structure!)?

... to get this. Some properties can only be observed through crystellising proteins, and this is a very difficult process with transmembrane proteins. This is why making drugs for certain receptors isn't a simple task, ...

How do receptor proteins get into urine??

... this question becuase it is probably very simple... I am doing a research project based on identivying a binding antibody to the cell surface transmembrane protein known as 'FGFR3' which is being developed as a biomarker urine test for bladder cancer (urothelial cell carcinoma), due to overexpression ...
