Enables the directed movement of phospholipids into, out of, within or between cells. Phospholipids are a class of lipids containing phosphoric acid as a mono- or diester.

Processes involved in the start of virus infection of cells.

disassembly of cell structures during apoptosis

The breakdown of structures such as organelles, proteins, or other macromolecular structures during apoptosis.

Interacting selectively with an odorant, any substance capable of stimulating the sense of smell.

The proteolytic degradation of lamins during apoptosis, leading to the irreversible breakdown of the nuclear lamina.

The proteolytic degradation of cytoskeletal proteins during apoptosis, leading to the collapse of cytoskeletal structures.

The chemical reactions involving tetrahydrobiopterin, the reduced form of biopterin (2-amino-4-hydroxy-6-(1,2-dihydroxypropyl)-pteridine). It functions as a hydroxylation coenzyme, e.g. in the conversion of phenylalanine to tyrosine.

programmed cell death, virus-infected cells

The process of apoptosis in cells infected with a virus.

programmed cell death, transformed cells

The process of apoptosis in transformed cells, cells that have undergone changes manifested by escape from control mechanisms, increased growth potential, alterations in the cell surface, karyotypic abnormalities, morphological and biochemical deviations from the norm.

The formation from simpler components of a pigment, any general or particular coloring matter in living organisms, e.g. melanin.

The achievement of highly specific, quantitative, temporal and spatial control of virus gene expression within the limited genetic resources of the viral genome.

Any process involved in the controlled movement of a cell.

The breakdown into simpler components of a pigment, any general or particular coloring matter in living organisms, e.g. melanin.

The orderly movement of cells from one site to another along a substrate such as the extracellular matrix; the migrating cell forms a protrusion that attaches to the substrate.
