ATP4B Antibody (N-term) [APR10860G]

Apical cell membrane {ECO:0000250|UniProtKB:P20648}; Single-pass type II membrane protein. Cell membrane {ECO:0000250|UniProtKB:P18597}; Single- pass type II membrane protein. Note=Localized in the apical canalicular membrane of parietal cells {ECO:0000250|UniProtKB:P20648}

Purified polyclonal antibody supplied in PBS with 0.09% (W/V) sodium azide. This antibody is purified through a protein A column, followed by peptide affinity purification.

The beta subunit of the gastric H (+) /K (+) ATPase pump which transports H (+) ions in exchange for K (+) ions across the apical membrane of parietal cells. Plays a structural and regulatory role in the assembly and membrane targeting of a functionally active pump (By similarity) . Within a transport cycle, the transfer of a H (+) ion across the membrane is coupled to ATP hydrolysis and is associated with a transient phosphorylation of the alpha subunit that shifts the pump conformation from inward-facing (E1) to outward-facing state (E2) . Interacts with the phosphorylation domain of the alpha subunit and functions as a ratchet, stabilizing the lumenal-open E2 conformation and preventing the reverse reaction of the transport cycle (By similarity) .
