Catalysis of the reaction: ATP + H2O = ADP + phosphate in the presence of double-stranded DNA, driving some other reaction.

A two-stranded helical polymer of the protein actin. Actin filaments are a major component of the contractile apparatus of skeletal muscle and the microfilaments of the cytoskeleton of eukaryotic cells. The filaments, comprising polymerized globular actin molecules, appear as flexible structures with a diameter of 5-9 nm. They are organized into a variety of linear bundles, two-dimensional networks, and three dimensional gels. In the cytoskeleton they are most highly concentrated in the cortex of the cell just beneath the plasma membrane.

Combining with inositol-1,4,5-triphosphate to initiate a change in cell activity.

A stable complex of seven subunits, two actin-related proteins, Arp2 and Arp3, and five novel proteins (ARPC1-5). Functions in the nucleation of actin filaments.

The joining of 2 or more lipid bilayer membranes that surround a cell.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

Interacting selectively with 5S ribosomal RNA, the smallest RNA constituent of a ribosome.

Penetrating at least one phospholipid bilayer of a plasma membrane. Also refers to the state of being buried in the bilayer with no exposure outside the bilayer.

The chemical reactions involving heterocyclic compounds, those with a cyclic molecular structure and at least two different atoms in the ring (or rings).

The chemical reactions involving glycerolipids, any lipid with a glycerol backbone. Diacylglycerol and phosphatidate are key lipid intermediates of glycerolipid biosynthesis.

The chemical reactions involving glyoxylate, the anion of glyoxylic acid, HOC-COOH.

The chemical reactions involving phosphatidylinositol, any glycophospholipid with its sn-glycerol 3-phosphate residue is esterified to the 1-hydroxyl group of 1D-myo-inositol.
