PROTEIN

PHYSICAL PROPERTIES

STRUCTURE

motifs/domains	11-14 transmembrane spanning segments
	two potential N-linked glycosylation motifs
	a conserved signaling motif
	multiple potential phosphorylation sites
	potential sites for N-glycosylation in its extracellular domains (Asn-138, Asn-144), essential for vitamin C transporter functionality (Subramanian 2008)

HOMOLOGY

intraspecies

paralog to SLC23A2

Homologene

FAMILY	xanthine/uracil permease family
	SLC23A subfamily

CATEGORY

transport carrier

SUBCELLULAR LOCALIZATION

plasma membrane

basic FUNCTION	role in transporting the dietary essential micronutrient ascorbic acid, the reduced and active form of vitamin C (Reidling 2008)
	role as a possible intracellular transporter and N-glycosylation is potentially required for SLC23A1 membrane targeting (Velho 2009)
	expressed mainly in epithelial tissues and is responsible for intestinal absorption and kidney reabsorption of ascorbic acid

INTERACTION

DNA

RNA

small molecule

protein

interacting with HNF1a, HNF1B (HNF-1alpha and/or HNF-1beta binding is required for its expression and may be involved in the coordinate regulation of whole body vitamin C status) (Michels 2009)
