Solute carrier family 5 member 3 (SLC5A3) is a member of SLC5A gene family, which shares five transmembrane segment inverted repeats of the LeuT structural family. SLC5A3 is expressed in brain, kidney and placenta. SLC5A3 gene is located on human chromosome 21q22.11.
Immunogen
SLC5A3 (NP_008864, 533 a.a. ~ 641 a.a) partial recombinant protein with GST tag. MW of the GST tag alone is 26 KDa.
Monoclonal Anti-SLC5A3 antibody produced in mouse has been used in dSTORM (direct stochastic optical reconstruction microscopy).
Biochem/physiol Actions
Solute carrier family 5 member 3 (SLC5A3) functions in cellular osmoregulation. Overexpression of SLC5A3 contributes to pathophysiology of Down syndrome. SLC5A3 acts as a transporter in hypotonic volume regulation of mammalian cells. SLC5A3 regulates millimolar intracellular concentrations of myo-inositol and promotes transepithelial myo-inositol transport in kidney, intestine, retina and choroid plexus.

Swelling-activated pathways for myo-inositol, one of the most abundant organic osmolytes in mammalian cells, have not yet been identified. The present study explores the SLC5A3 protein as a possible transporter of myo-inositol in hyponically swollen HEK293 cells. To address this
