For example, membrane receptors bind and respond to specific molecules outside the cell, such as hormones, neurotransmitters, the extracellular matrix, and attachment molecules on other cells.

Because membrane receptors interact with both extracellular signals and molecules within the cell, they permit signaling molecules to affect cell function without actually entering the cell.

Lipids in cell membranes regulate the activity of a cancer-linked protein, cell biologists at RIKEN have discovered. This ...
