function:Mediates electroneutral exchange of protons for Na(+) and K(+) across endomembranes. May contribute to Golgi volume and cation homeostasis.,miscellaneous:Is not inhibited by amiloride but by benzamil and quinine.,similarity:Belongs to the monovalent cation:proton antiporter 1 (CPA1) transporter (TC 2.A.36) family.,subunit:Interacts with SCAMP1, SCAMP2 and SCAMP5; may participate in its shuttling from trans-Golgi network to recycling endosomes.,tissue specificity:Ubiquitously expressed.,
Golgi apparatus, trans-Golgi network membrane ; Multi-pass membrane protein . Recycling endosome membrane ; Multi-pass membrane protein . Cell membrane ; Multi-pass membrane protein .
