Solute carrier family 9, subfamily B (NHA2, cation proton antiporter 2), member 2 is a
protein
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residue (biochemistry), residues. Proteins perform a vast array of functions within organisms, including Enzyme catalysis, catalysing metab ...

gene
In biology, the word gene has two meanings. The Mendelian gene is a basic unit of heredity. The molecular gene is a sequence of nucleotides in DNA that is transcribed to produce a functional RNA. There are two types of molecular genes: protei ...

Function
Sodium–hydrogen antiporter The sodium–hydrogen antiporter or sodium–proton exchanger (Na+/H+ exchanger or NHX) is a membrane protein that transports Na+ into the cell, and H+ out of the cell (antiport).
Function
They are found in the membranes of many cells, and espe ...
s, such as NHEDC2, convert the proton motive force established by the respiratory chain or the F1F0 mitochondrial
ATPase
ATPases (, Adenosine 5'-TriPhosphatase, adenylpyrophosphatase, ATP monophosphatase, triphosphatase, ATP hydrolase, adenosine triphosphatase) are a class of enzymes that catalyze the decomposition of ATP into ADP and a free phosphate ion or ...
into sodium gradients that drive other energy-requiring processes, transduce environmental signals into cell responses, or function in drug efflux.
