RBS-ChAT-6xHis-Terminator
This part consists of B0034 RBS, human choline acetyltransferase (CHAT) gene with C-terminal His tag, and B0015 terminator.
Usage and Biology
Choline acetyltransferase (CHAT) catalyses synthesis of acetylcholine from choline and acetyl-CoA. Acetylcholine is a versatile neurotransmitter that has mediates signalling in central nervous system and brain as well as peripheral nervous system. Acetylcholine has been implicated in cognition, memory, and learning functions [1]. Acetylcholine is also a principal neurotransmitter in vagal nerve, which connects brain to digestive system [2]. Acetylcholine released at the efferent vagus nerve endings decreases the excessive production of inflammatory cytokines such as IL-1, IL-6 and tumor necrosis factor-α (TNF-α) [3]. These inflammatory cytokines are elevated in patients with major depression [4] and have been shown to induce depressive-like behaviour in mice [5] and humans [6].
In humans, CHAT expression requires microbiota-dependent signalling and does not begin until microbial gut colonization after birth. [7]. Hence, imbalances in gut microflora can lead to disrupted acetylcholine activity, which has been strongly linked to depression. We propose to explore the acetylcholine-producing probiotics as a solution for restoring the proper functioning of cholinergic system in patients with depression and other psychiatric diseases.
