High-affinity choline transporter 1 (CHT1)

Target
CHT1
Molecular classification
Transporter, Sodium/glucose cotransporter family (SLC5)
01

Overview

The high-affinity choline transporter (CHT1), encoded by the SLC5A7 gene, is a critical membrane protein responsible for the sodium- and chloride-dependent uptake of choline into presynaptic nerve terminals. This process is essential for the synthesis of acetylcholine (ACh), a key neurotransmitter in both the central and peripheral nervous systems. CHT1 activity is rate-limiting in cholinergic signaling, ensuring efficient reutilization of choline derived from synaptic ACh breakdown, maintaining neurotransmitter supply during sustained neuronal activity. Dysfunction or genetic mutations affecting SLC5A7/CHT can impair cognitive functions due to reduced cholinergic tone.
