Catalysis of the reaction: an aldehyde + NAD(P)+ + H2O = an acid + NAD(P)H + H+.

Catalysis of the reaction: an aldehyde + H2O + O2 = a carboxylic acid + H2O2.

Catalysis of the reaction: alditol + NADP+ = aldose + NADPH + H+.

Catalysis of the NADPH-dependent reduction of carbonyl compounds.

Catalysis of the reaction: 3'-phosphoadenosine 5'-phosphosulfate (PAPS) + a phenolic steroid = adenosine 3',5'-bisphosphate + steroid O-sulfate.

The process of introducing a phosphoric group into a molecule, usually with the formation of a phosphoric ester, a phosphoric anhydride or a phosphoric amide.

Invasion of a host cell by another cell (microorganism) or virus.

regulation of Ras protein signal transduction

Any process that modulates the frequency, rate or extent of Ras protein signal transduction.

The process of removing one or more phosphoric (ester or anhydride) residues from a molecule.

Any specialized areas of the plasma membranes of adjacent cells where the membranes are 2-4 nm apart and penetrated by a connexon.

The progressive compaction of dispersed interphase chromatin into threadlike chromosomes prior to mitotic or meiotic nuclear division, or during apoptosis, in eukaryotic cells.

positive regulation of Ras protein signal transduction

Any process that activates or increases the rate of Ras protein signal transduction.

Catalysis of the removal of one of the two phosphate groups of an inositol bisphosphate.

An assembly of six molecules of connexin, made in the Golgi apparatus and subsequently transported to the plasma membrane, where docking of two connexons on apposed plasma membranes across the extracellular space forms a gap junction.

The morphological and physiological alterations undergone by the nucleus during apoptosis.

A belt-like region of very close contact between the plasma membranes of adjacent cells so that the intercellular space is completely occluded. They occur in epithelia and brain endothelia.

The compaction of chromatin during apoptosis.

Catalysis of the reaction: phosphatidylinositol-3,4,5-trisphosphate + H2O = phosphatidyl inositol-4,5-bisphosphate + phosphate.
