Na+,K+-ATPase (NKA) is a membrane protein which assists in maintaining the electrochemical potential across the cell membrane. It has been suggested that the oligomerization of NKA may play a role in intracellular regulation of NKA activity. Monte Carlo simulations of NKA on a picket-fence membrane model were performed to examine if clustering has an effect on NKA efficiency. The results show that for a simple model of NKA interaction, oligomerization may drastically reduce the efficiency as measured in ATP turnover rate. Introducing a rate limit shows a clear separation between monomers and higher levels of oligomerization.
