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 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.

Catalysis of the insertion of a dCMP residue opposite a template abasic site in DNA.

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 regulated release of acid by a cell or group of cells.

Interacting selectively with any triester of glycerol.

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.

Catalysis of the reaction: a nucleoside diphosphate + H2O = a nucleotide + phosphate.

Catalysis of the reaction: a nucleoside triphosphate + H2O = nucleoside diphosphate + phosphate.

The process of removing sections of the primary RNA transcript to remove sequences not present in the mature form of the RNA and joining the remaining sections to form the mature form of the RNA.

Catalysis of the reaction: 2 peroxide radical + 2 H+ = O2 + H2O2.

Catalysis of the phosphorylation of IkappaB, thereby targeting this for proteasomal degradation and allowing the nuclear translocation of kB. Composed of alpha, beta and gamma subunits, the latter not having kinase activity but presumed to play a regulatory role.

Catalysis of the reaction: cholesterol + reduced adrenal ferredoxin + O2 = pregnenolone + 4-methylpentanal + oxidized adrenal ferredoxin + H2O.
