Combining with prostacyclin (PGI(2)) to initiate a change in cell activity.

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.

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.

The directed movement of a cofactor into, out of, within or between cells. A cofactor is a substance that is required for the activity of an enzyme or other protein.
