ATP5A1 Antibody - #DF3806

Mitochondrial membrane ATP synthase (F(1)F(0) ATP synthase or Complex V) produces ATP from ADP in the presence of a proton gradient across the membrane which is generated by electron transport complexes of the respiratory chain. F-type ATPases consist of two structural domains, F(1) - containing the extramembraneous catalytic core, and F(0) - containing the membrane proton channel, linked together by a central stalk and a peripheral stalk. During catalysis, ATP synthesis in the catalytic domain of F(1) is coupled via a rotary mechanism of the central stalk subunits to proton translocation. Subunits alpha and beta form the catalytic core in F(1). Rotation of the central stalk against the surrounding alpha(3)beta(3) subunits leads to hydrolysis of ATP in three separate catalytic sites on the beta subunits. Subunit alpha does not bear the catalytic high-affinity ATP-binding sites (By similarity). Binds the bacterial siderophore enterobactin and can promote mitochondrial accumulation of enterobactin-derived iron ions.

The N-terminus is blocked.

Acetylated on lysine residues. BLOC1S1 is required for acetylation.

Mitochondrion. Mitochondrion inner membrane>Peripheral membrane protein>Matrix side. Cell membrane>Peripheral membrane protein>Extracellular side.
Note: Colocalizes with HRG on the cell surface of T-cells (PubMed:19285951).

Fetal lung, heart, liver, gut and kidney. Expressed at higher levels in the fetal brain, retina and spinal cord.

F-type ATPases have 2 components, CF(1) - the catalytic core - and CF(0) - the membrane proton channel. CF(1) has five subunits: alpha(3), beta(3), gamma(1), delta(1), epsilon(1). CF(0) has three main subunits: a, b and c (By similarity). Interacts with ATPAF2. Interacts with HRG; the interaction occurs on the surface of T-cells and alters the cell morphology when associated with concanavalin (in vitro). Interacts with PLG (angiostatin peptide); the interaction inhibits most of the angiogenic properties of angiostatin. Component of an ATP synthase complex composed of ATP5PB, ATP5MC1, ATP5F1E, ATP5PD, ATP5ME, ATP5PF, ATP5MF, MT-ATP6, MT-ATP8, ATP5F1A, ATP5F1B, ATP5F1D, ATP5F1C, ATP5PO, ATP5MG, ATP5MD and ATP5MPL (By similarity). Interacts with BLOC1S1. Interacts with BCL2L1 isoform BCL-X(L); the interaction mediates the association of BCL2L1 isoform BCL-X(L) with the mitochondrial membrane F(1)F(0) ATP synthase and enhances neurons metabolic efficiency (By similarity). Interacts with CLN5 and PPT1 (By similarity).

Belongs to the ATPase alpha/beta chains family.
