SLC23A1 Antibody

What is SLC23A1 and what is its biological significance?

SLC23A1 encodes the sodium-dependent vitamin C transporter 1 (SVCT1), a protein primarily responsible for whole-body vitamin C homeostasis and regulation of circulating vitamin C levels . The gene spans 16096 bp, contains 15 exons, and maps to human chromosome 5q31.2-31.3 . Its genomic structure includes classical CAAT and TATA 1 boxes, along with two AP-1 and one GATA1 binding sites . SVCT1 plays a crucial role in vitamin C absorption in the gastrointestinal tract and reabsorption in the renal system, making it vital for maintaining appropriate vitamin C levels throughout the body .

What types of SLC23A1 antibodies are currently available for research?
