Description:
Anti-Choline Acetyltransferase
Alternate Description:
Choline Acetyltransferase Antibody
Trade Name:
Chemicon (Millipore)
Product Overview:
Catalyzes the reversible synthesis of acetylcholine (ACh) from acetyl CoA and choline at cholinergic synapses.
Specificity:
Choline acetyltransferase found in cholinergic neurons in brain and spinal cord.
Molecular Weight:
70/74 kDa
Immunogen:
Human placental enzyme.
Background Information:
Acetylcholine (ACh) is a common neurotransmitter for motoneurons, preganglionic autonomic neurons, postganglionic parasympathetic neurons, a variety of brain regions and some emerging neuron-like stem cells. The metabolism of Ach is relatively simple, involving only two enzymes: choline acetyltransferase (ChAT) for synthesis and acetylcholinesterase (AChE) for degradation. Further, acetylcholine has little function in neurons other than neurotransmission and seems to be neuron specific. It seems that only cholinergic neurons have significant amounts of ChAT making anti-choline acetyltransferase a useful specific marker.

Entrez Gene Summary:
Cholinergic systems are implicated in numerous neurologic functions. Alteration in some cholinergic neurons may account for the disturbances of Alzheimer disease. The protein encoded by this gene synthesizes the neurotransmitter acetylcholine. Alternative splice variants have been found that contain alternative 5' untranslated exons. Three of the four described splice variants encode identical 69 kDa proteins while one variant encodes both the 69 kDa and a larger 82 kDa protein.
UniProt Summary:
FUNCTION: SwissProt: P28329 # Catalyzes the reversible synthesis of acetylcholine (ACh) from acetyl CoA and choline at cholinergic synapses.
SIZE: 748 amino acids; 82568 Da
DISEASE: SwissProt: P28329 # Defects in CHAT are the cause of familial infantile myasthenia gravis 2 (FIMG2) [MIM:254210, 254200]; also known as CMS-EA. FIMG2 patients have myasthenic symptoms since birth or early infancy, negative tests for anti-AChR antibodies, and abrupt episodic crises with increased weakness, bulbar paralysis, and apnea precipitated by undue exertion, fever, or excitement. Inheritance is autosomal recessive.
SIMILARITY: SwissProt: P28329 ## Belongs to the carnitine/choline acetyltransferase family.
