Choline Transporter Protein

Molecular classification
Transporter, Solute Carrier Family, Membrane protein
01

Overview

The choline transporter protein family encompasses several membrane transporters responsible for the uptake of choline, an essential nutrient. These include the high-affinity choline transporter 1 (CHT1/SLC5A7), choline transporter-like proteins (CTLs/SLC44 family), and polyspecific organic cation transporters (OCTs). CHT1 is crucial for acetylcholine synthesis in cholinergic neurons. CTLs play roles in both plasma membrane and mitochondrial choline transport. Dysfunction or inhibition of these transporters can impact neurotransmission and cell proliferation, making them relevant in neurodegenerative diseases and cancer.
