Combining with a nucleotide to initiate a change in cell activity. A nucleotide is a compound that consists of a nucleoside esterified with a phosphate molecule.

Combining with a pheromone to initiate a change in cell activity.

Any process involved in forming the mature 3' end of an RNA molecule.

Increases the activity of a protease, any enzyme catalyzes the hydrolysis peptide bonds.

Any process involved in forming the mature 3' end of an mRNA molecule.

Catalysis of the transfer of an L-fucosyl group from GDP-beta-L-fucose to an acceptor molecule to form an alpha(1,2)-linkage.

The chemical reactions involving urea, the water soluble compound O=C-(NH2)2, produced in the liver by the ornithine cycle. It is the main nitrogen-containing excretion product in ureotelic animals.

The directed movement of vitamins into, out of, within or between cells. A vitamin is one of a number of unrelated organic substances that occur in many foods in small amounts and that are necessary in trace amounts for the normal metabolic functioning of the body.

Catalysis of the reaction: (3S)-3-hydroxyacyl-CoA = trans-2-enoyl-CoA + H2O.

Catalysis of the reaction: S-adenosyl-L-methionine + dimethyl sulfide = S-adenosyl-L-homocysteine + trimethylsulfonium.

Catalysis of the carrier-mediated transfer of one or more substances across a membrane. Transport occurs in three ways: uniport, a single species is transported by facilitated diffusion in a process not coupled to the utilization of a primary source of energy; antiport, two or more species are transported in opposite directions in a tightly coupled process not directly linked to a form of energy other than chemiosmotic energy; and symport, two or more species are transported together in the same direction in a tightly coupled process not directly linked to a form of energy other than chemiosmotic energy.

Signaling at short range between cells or tissues of different ancestry and developmental potential that results in one cell or tissue effecting a developmental change in the other.
