Research

Structure and Function of Membrane Proteins

The function and regulation of membrane proteins involved in the transfer of solutes (channels and transporters) and of information (receptors) across the plasma membrane are the subjects of research in this laboratory.

The particular proteins under study are the insulin receptor, the (Na,K) ATPase, an insulin-activated cation channel, channels and transporters for ATP, and an ecto-apyrase.
