Solute carrier organic anion transporter family member 4C1 (Slco4c1)

May participate in the regulation of membrane transport of ouabain. Involved in the uptake of the dipeptidyl peptidase-4 inhibitor sitagliptin and hence may play a role in its transportation into and out of renal proximal tubule cells.

May be involved in the initial step of this transport pathway of digoxin and various compounds to the urine in the kidney. May be involved in sperm maturation by allowing directed movement of organic anions and chemicals within or between cells.
