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.

A healthy brain balances “activate” and “inhibit” signaling in its neural microcircuitry, with the inhibitory signaling often provided by cell receptors for the neurotransmitter GABA.   Unexpected ...

This finding is only one example of an intermolecular interaction that regulates ERBB receptors. However, many parts of the ERBB receptors themselves can influence regulation. Indeed, there are ...
