Anti-Choline Acetyltransferase/Chat Antibody Picoband®

Choline acetyltransferase  (commonly abbreviated as  ChAT, but sometimes  CAT) is a  transferase  enzyme  responsible for the synthesis of the  neurotransmitter  acetylcholine. In humans, the choline acetyltransferase enzyme is encoded by the  CHAT  gene. This gene product is a characteristic feature of cholinergic neurons, and changes in these neurons may explain some of the symptoms of Alzheimer's disease. Polymorphisms in this gene have been associated with Alzheimer's disease and mild cognitive impairment. Mutations in this gene are associated with congenital myasthenic syndrome associated with episodic apnea. Multiple transcript variants encoding different isoforms have been found for this gene, and some of these variants have been shown to encode more than one isoform.
