negative regulation of protein amino acid phosphorylation

Any process that stops, prevents or decreases the rate of addition of phosphoric groups to amino acids within a protein.

positive regulation of protein amino acid phosphorylation

Any process that activates or increases the rate of addition of phosphoric groups to amino acids within a protein.

Catalysis of the hydrolysis of carboxyl terminal peptide linkages in oligopeptides or polypeptides; a serine residue is at the active center.

Interacting selectively with cholesterol (cholest-5-en-3-beta-ol); the principal sterol of vertebrates and the precursor of many steroids, including bile acids and steroid hormones.

The multiplication or reproduction of endothelial cells, resulting in the rapid expansion of a cell population. Endothelial cells are thin flattened cells which line the inside surfaces of body cavities, blood vessels, and lymph vessels, making up the endothelium.

Any process that modulates the frequency, rate or extent of hydrolase activity, the catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3.

Catalysis of the release of a C-terminal amino acid with a broad specificity.

regulation of endothelial cell proliferation

Any process that modulates the frequency, rate, or extent of endothelial cell proliferation.

negative regulation of endothelial cell proliferation

Any process that stops, prevents, or reduces the rate or extent of endothelial cell proliferation.

Any process that modulates the frequency, rate or extent of transferase activity, the catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2.

Catalysis of an oxidation-reduction (redox) reaction in which the hydrogen donor and acceptor are the same molecule, and no oxidized product appears.
