Protein Information (annotations from UniProt)

Database IDHIV0000603
UniProt IDQ15822
Primary gene name(s)CHRNA2
Synonym gene name(s)unknown
Protein nameNeuronal acetylcholine receptor subunit alpha-2
Protein functionAfter binding acetylcholine, the AChR responds by an extensive change in conformation that affects all subunits and leads to opening of an ion-conducting channel across the plasma membrane.
Subcellular locationCell junction, synapse, postsynaptic cell membrane;
Multi-pass membrane protein. Cell membrane;
