Any process that modulates the size of a cell.

The translocation, or flipping, of phospholipid molecules from one monolayer of a plasma membrane to the opposite monolayer.

Catalysis of the reaction: sphingosine 1-phosphate + H2O = sphingosine + phosphate.

The enzymatic release of energy from organic compounds (especially carbohydrates and fats) which either requires oxygen (aerobic respiration) or does not (anaerobic respiration).

Interacting selectively with a histone, any of a group of water-soluble proteins found in association with the DNA of plant and animal chromosomes. They are involved in the condensation and coiling of chromosomes during cell division and have also been implicated in nonspecific suppression of gene activity.

A clathrin-coated, membrane-bounded intracellular vesicle formed by invagination of the plasma membrane around an extracellular substance.

The formation from simpler components of phosphagen, any of a group of guanidine phosphates that occur in muscle and can be used to regenerate ATP from ADP during muscular contraction.

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.

Catalysis of the conversion of phosphatidylinositol-3-phosphate, phosphatidylinositol-4-phosphate, and phosphatidylinositol-3,5-bisphosphate, but not PI-4,5-bisphosphate, to phosphatidylinositol; PPIPase activity is a key regulator of membrane trafficking and actin cytoskeleton organization.

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.
