CATEGORY

transport channel

SUBCELLULAR LOCALIZATION	plasma membrane
text	predominantly localized to the epithelial cell membranes, in case of ciliated tracheal cells it was restricted to the apical membrane

basic FUNCTION	expressed in cholinergic neurons and efficiently transported to axon terminals where it controls the rate-limiting step in acetylcholine synthesis
	is present in central cholinergic neurons and cholinergic neurotransmission is important for cognitive and behavioral functions
	critical determinant of synaptic acetylcholine (ACh) synthesis and release at the neuromuscular junction (NMJ)

INTERACTION

DNA

RNA

small molecule

protein

NEDD4L mediated ubiquitination regulates the cell surface expression of SLC5A7

cell & other

REGULATION

Other

overexpressed CHAT enhanced transcription of the SLC5A7 gene

ASSOCIATED DISORDERS

corresponding disease(s)

DHMN7A , CMS20

Susceptibility

to heart rate variability

Variant & Polymorphism other	heart rate variability is associated with polymorphic variation in SLC5A7

Candidate gene	SLC5A7 or its regulation should be considered as a potential contributor to idiopathic motor neuronopathies
Marker
Therapy target
	System Type Disorder Pubmed neurology neurodegenerative alzheimer drugs which inhibit the interaction between SLC5A7 and NEDD4L might be useful for diseases involving decrease in acetylcholine level such as Alzheimer disease
