what are the functions that carried out by membrane protiens? :D

be more specific :roll: there are many different membrane proteins that all have different functions.

i knew that the protiens carry out few functions such as binding sites for hormone, electrons carrier, channels for passive transport and pupms for active transport. is there any other functions that carry out by the membrane protien? :D

Hi

Membrane proteins are very important in cell signalling, which by itself will bring forth a lot of functions including apoptosis (programmed cell death), cell migration, cell division etc.

So one important function of membrane proteins also include signalling.

and what about gap junctions and the the other junctions between cells. They contain also proteins associated with the cellmembrane. Thus they can interact with the cytoskeleton.

You should be more specific next time, but membrane proteins have to do with singalling, (programmed cell death), cell migration, cell division etc.

There are also proteins on cell membranes that control diffusion of molecules across the membrane (including those that aid in facilitated diffusion) and there are some helper proteins that connect helper cells with phloem cells (plants) and also help create pseudopodia and the like, out of microtubules from the cytoskeleton. The list goes on and on; so i would be more specific...... :shock:
