proton pump

General Information (Source: NCBI Gene,UniProt)

Text mining Term proton pump
UniProt ID PMA1_WHEAT
Name Plasma membrane ATPase
Proton pump
Gene Names ha1
Taxonomy Triticum aestivum

General annotation

Function The plasma membrane ATPase of plants and fungi is a hydrogen ion pump. The proton gradient it generates drives the active transport of nutrients by H(+)-symport. The resulting external acidification and/or internal alkinization may mediate growth responses (By similarity).
Subcellular location Cell membrane; Multi-pass membrane protein.
