A protein serine/threonine phosphatase that is polycation-stimulated (PCS), being directly stimulated by protamine, polylysine, or histone H1; it constitutes a subclass of several enzymes activated by different histones and polylysine.

Catalysis of the reaction: UDP-glucose + ecdysteroid = UDP + glucosyl-ecdysteroid.

Catalysis of the reaction: UDP-glucuronate + ecdysteroid = UDP + glucuronosyl-ecdysteroid.

Increases the activity of guanylate cyclase.

Stops, prevents or reduces the activity of guanylate cyclase.

The regulated release of growth hormone from secretory granules into the blood.

Interacting selectively with DNA sequences encoding ribosomal RNA.

Repression of transcription of ribosomal DNA by the formation of heterochromatin.

The nonsense-mediated mRNA decay pathway degrades mRNAs transcribed from genes in which an amino-acid codon has changed to a nonsense codon; this prevents the translation of such mRNAs into truncated, and potentially harmful, proteins.

Catalysis of the reaction: arachidonate + O2 = (5Z,8Z,11Z,13E)-(15S)-15-hydroperoxyicosa-5,8,11,13-tetraenoate.

Any process that initiates the activity of the inactive enzyme MAP kinase kinase kinase.

The initiation of the activity of the inactive enzyme MAP kinase kinase by phosphorylation by a MAPKKK.

The covalent or conformational alteration of one or more fatty acids in a lipid, resulting in a change in that lipid.

The initiation of the activity of the inactive enzyme MAP kinase by phosphorylation by a MAPKK.

Covalent attachment of a glycosyl residue to a lipid molecule.

Any process that terminates the activity of the active enzyme MAP kinase.

The directed movement of a MAP kinase to the nucleus upon activation.

The action of a molecule that contributes to the structural integrity of an epidermal cutaneous structure.

structural constituent of cutaneous appendage

The action of a molecule that contributes to the structural integrity of cutaneous epidermal structures such as hairs, scales, or feathers.

Catalysis of the hydroxylation of sphingolipid long chain bases.
