Protein characteristic of the postsynaptic membrane. In a chemical synapse, the postsynaptic membrane is the membrane that receives a signal (binds neurotransmitter) from the presynaptic cell and responds via depolarisation or hyperpolarisation. The postsynaptic membrane is separated from the presynaptic membrane by the synaptic cleft.
The membrane consists of a double-layer (a phospholipid bilayer) of amphipathic lipids. The hydrophobic ends face each other on the inside, and the hydrophilic ends are on the outsides of the membrane. That way, the hydrophobic regions do not interact with water, and the hydrophilic regions do. Both parts of each phospholipid molecule are happy.. Other molecules are also found in the membrane.
