An actin filament bundle in which the filaments are tightly packed (approximately 10-20 nm apart) and oriented with the same polarity.

An actin filament bundle in which the filaments are loosely packed (approximately 30-60 nm apart) and arranged with opposing polarities; the loose packing allows myosin (usually myosin-II) to enter the bundle.

An assembly of actin filaments that are on the same axis but may be oriented with the same or opposite polarities and may be packed with different levels of tightness.

A protein-DNA complex consisting of a higher-order oligomer of strand exchange proteins (recombinases) on single-stranded DNA.

The chemical reactions and pathways involving erythrose 4-phosphate/phosphoenolpyruvate family amino acid.

The chemical reactions and pathways resulting in the breakdown of erythrose 4-phosphate/phosphoenolpyruvate family amino acid.

The chemical reactions and pathways involving ketone body.

Any process that stops, prevents or reduces the frequency, rate or extent of acrosome reaction.

Any process that modulates the frequency, rate or extent of the acrosome reaction.

Any process that modulates the frequency, rate or extent of macrophage colony-stimulating factor signaling pathway.

Any process that modulates the frequency, rate or extent of cellular response to macrophage colony-stimulating factor stimulus.

Any process that stops, prevents or reduces the frequency, rate or extent of macrophage colony-stimulating factor signaling pathway.

Any process that activates or increases the frequency, rate or extent of macrophage colony-stimulating factor signaling pathway.

A multiprotein complex involved in damage recognition, DNA helix unwinding, and endonucleolytic cleavage at the site of DNA damage.

A protein-DNA complex formed through interaction of the protein(s) with an interferon-stimulated response element (ISRE) in the DNA.

A protein-DNA-RNA complex composed of RNA polymerase, template DNA, and an RNA transcript.

A macromolecular complex containing protein, DNA, and RNA molecules.

A plasma membrane that is part of a sperm cell.

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