Recombinant Human Electrogenic sodium bicarbonate cotransporter 4 (SLC4A5), Truncated

Uniprot Id

Q9BY07

Target Species

Human

Target Name

SLC4A5

Target Full Name

Electrogenic sodium bicarbonate cotransporter 4

Target Function

Mediates sodium- and bicarbonate-dependent electrogenic sodium bicarbonate cotransport, with a Na(+):HCO3(-) stoichiometry of 2:1. May have a housekeeping function in regulating the pH of tissues in which it is expressed. May play a role in mediating Na(+):HCO3(-) cotransport in hepatocytes and intrahepatic cholangiocytes. Also may be important in protecting the renal paranchyma from alterations in urine pH.

Target Subcellular Location

Apical cell membrane; Multi-pass membrane protein.

Target Protein Families

Anion exchanger (TC 2.A.31) family

Target Tissue Specificity

Highest expression observed in liver, spleen and testis; moderate expression in the choroid plexus, hippocampus, cerebrum and cerebellum of brain, and in kidney cortex and kidney medulla. Also observed in heart, pancreas, muscle, lung, placenta, stomach a

Target Synonyms

Electrogenic sodium bicarbonate cotransporter 4; MGC129662; NBC4; NBCe2; S4A5_HUMAN; SLC4A5; Solute carrier family 4 member 5; Solute carrier family 4 sodium bicarbonate cotransporter member 5

Target Background

This gene encodes a member of the sodium bicarbonate cotransporter (NBC) family, part of the bicarbonate transporter superfamily. Sodium bicarbonate cotransporters are involved in intracellular pH regulation and electroneural or electrogenic sodium bicarbonate transport. This protein is thought to be an integral membrane protein. Multiple transcript variants encoding different isoforms have been found for this gene, but the biological validity of some variants has not been determined.
