IPR005772

Description

IPR005772 is a ATPase, V1 complex, subunit F, eukaryotic.

<p>Transmembrane ATPases are membrane-bound enzyme complexes/ion transporters that use ATP hydrolysis to drive the transport of protons across a membrane. Some transmembrane ATPases also work in reverse, harnessing the energy from a proton gradient, using the flux of ions across the membrane via the ATPase proton channel to drive the synthesis of ATP.</p> <p>V-ATPases (also known as V1V0-ATPase or vacuolar ATPase) are found in the eukaryotic endomembrane system, and in the plasma membrane of prokaryotes and certain specialised eukaryotic cells. V-ATPases hydrolyse ATP to drive a proton pump, and are involved in a variety of vital intra-and inter-cellular processes such as receptor mediated endocytosis, protein trafficking, active transport of metabolites, homeostasis and neurotransmitter release [[cite:PUB00020609]]. V-ATPases are composed of two linked complexes: the V1 complex (subunits A-H) contains the catalytic core that hydrolyses ATP, while the V0 complex (subunits a, c, c', c'', d) forms the membrane-spanning pore. V-ATPases may have an additional role in membrane fusion through binding to t-SNARE proteins [[cite:PUB00020608]].</p> <p>This entry represents subunit F found in the V1 complex of V-ATPases in eukaryotes. Subunit F is a 16kDa protein that is required for the assembly and activity of V-ATPase, and has a potential role in the differential targeting and regulation of the enzyme for specific organelles. This subunit is not necessary for the rotation of the ATPase V1 rotor, but it does promote catalysis [[cite:PUB00020639]].</p>

GO term Namespace Name Definition Relationships
Cellular component Proton-transporting V-type ATPase, V1 domain A protein complex that forms part of a proton-transporting V-type ATPase and catalyzes ATP hydrolysis. The V1 complex consists of: (1) a globular headpiece with three alternating copies of subunits A and B that form a ring, (2) a central rotational stalk composed of single copies of subunits D and F, and (3) a peripheral stalk made of subunits C, E, G and H. Subunits A and B mediate the hydrolysis of ATP at three reaction sites associated with subunit A.
Molecular function Proton-transporting ATPase activity, rotational mechanism Enables the transfer of protons from one side of a membrane to the other according to the reaction: ATP + H2O + H+(in) = ADP + phosphate + H+(out), by a rotational mechanism.
Biological process Proton transmembrane transport The directed movement of a proton across a membrane.
