The processes by which the axon of a neuron is insulated, and that insulation maintained, thereby preventing dispersion of the electrical signal.

Interacting selectively with any part of a bacterial cell.

The formation from simpler components of compounds derived from amino acids, organic acids containing one or more amino substituents.

Interacting selectively with any part of a Gram-negative bacterial cell.

The process by which all major lipid classes are redistributed within the plasma membrane following cell activation or injury, resulting in surface exposure of phosphatidylserine (PS) and phosphatidylethanolamine (PE). Cell surface-exposed PS can serve as receptor sites for coagulation enzyme complexes, and contributes to cell clearance by the reticuloendothelial system.

Interacting selectively with a SH3 domain (Src homology 3) of a protein, small protein modules containing approximately 50 amino acid residues found in a great variety of intracellular or membrane-associated proteins.

The maintenance of muscle fibers after their formation to allow normal functioning.

Enables the directed movement of cholesterol into, out of, within or between cells. Cholesterol is the principal sterol of vertebrates and the precursor of many steroids, including bile acids and steroid hormones.

The process by which a virion enters a host cell, including virion attachment and penetration.

Any process that modulates the levels of viral proteins in a cell.

A complex possessing an activity that couples ATP hydrolysis to the severing of microtubules; usually a heterodimer comprising a catalytic subunit (often 60kDa) and a regulatory subunit (often 80 kDa).

Catalysis of the reaction: ATP + (DNA-directed RNA polymerase) = ADP + phospho-(DNA-directed RNA polymerase).

The orderly movement of a germ cell, a cell specialized to produce haploid gametes, through the embryo from its site of production to the place where the gonads will form.

The asymmetric division of cells to produce two daughter cells with different developmental potentials. It is of fundamental significance for the generation of cell diversity.
