Membrane 'neighborhood' helps transporter protein regulate cell signaling

Summary

A study published by Phys.org reveals that the protein ABCC4 plays a crucial role in regulating the levels of cyclic AMP (cAMP) within cells, ensuring that signals are accurately transmitted without unintended activation of other pathways. The research highlights the importance of ABCC4's positioning in maintaining local control of cAMP, although the exact mechanisms of its localization remain unclear.
