What molecule or ion capable of donating a hydron, is associated with Solute carrier family 10 member 4 and the promotion of acidification in mice?
Solute carrier family 10 member 4: Solute carrier family 10 member 4 is a protein that in humans is encoded by the SLC10A4 gene. Solute carrier family 10 member 4:  In mice, it appears to promote acidification of synaptic vesicles containing monoamines, enhancing their uptake, and is co-expressed with VMAT2 and VAChT. Acid: An acid is a molecule or ion capable of donating a hydron (proton or hydrogen ion H), or, alternatively, capable of forming a covalent bond with an electron pair (a Lewis acid).
