2.A.1.13.11
Solute carrier family 16, member 5 (monocarboxylic acid transporter 6) of 505 aas and 12 TMSs. Found on the luminal side of small intestinal epithelial cells (Kohyama et al. 2013). MCT6 mediates uptake of nateglinide, an oral hypoglycemic agent. The K(t) for nateglinide is 46 μM. Thus, MCT6 may play a role in the intestinal absorption of nateglinide, although other transporters are also likely to be involved (Kohyama et al. 2013).
