    SUBCELLULAR LOCALIZATION     plasma membrane
    text
  • predominantly localized to the epithelial cell membranes, in case of ciliated tracheal cells it was restricted to the apical membrane
  • basic FUNCTION
  • expressed in cholinergic neurons and efficiently transported to axon terminals where it controls the rate-limiting step in acetylcholine synthesis
  • is present in central cholinergic neurons and cholinergic neurotransmission is important for cognitive and behavioral functions
  • critical determinant of synaptic acetylcholine (ACh) synthesis and release at the neuromuscular junction (NMJ)
