The function of a family of small chemotactic cytokines; their name is derived from their ability to induce directed chemotaxis in nearby responsive cells. All chemokines possess a number of conserved cysteine residues involved in intramolecular disulfide bond formation. Some chemokines are considered pro-inflammatory and can be induced during an immune response to recruit cells of the immune system to a site of infection, while others are considered homeostatic and are involved in controlling the migration of cells during normal processes of tissue maintenance or development. Chemokines are found in all vertebrates, some viruses and some bacteria.

Catalysis of the reaction: N-acetylputrescine + H(2)O = acetate + putrescine.

Catalysis of the reaction: N-acetylindoxyl + O2 = N-acetylisatin + unknown.

Catalysis of the reaction: acetate + diphosphate = acetyl phosphate + phosphate.

Catalysis of the reaction: CDP-abequose + D-mannosyl-L-rhamnosyl-D-galactose-1-diphospholipid = CDP + D-abequosyl-D-mannosyl-rhamnosyl-D-galactose-1-diphospholipid.

Catalysis of the reaction: acetoacetyl-CoA + H(2)O = acetoacetate + CoA + H(+).

Catalysis of the reaction: acetoacetate + H(+) = acetone + CO(2).

The action of a molecule that contributes to the structural integrity of the chitin-based cuticle of a pupa. An example of this is found in Drosophila melanogaster.

The action of a molecule that contributes to the structural integrity of the chitin-based cuticle of a larva. An example of this is found in Drosophila melanogaster.

Binding to a catenin beta subunit.

The action of a molecule that contributes to the structural integrity of the chitin-based cuticle of an adult organism. An example of this is found in Drosophila melanogaster.

OBSOLETE. A calcium-dependent cell adhesion protein (type I membrane protein) that interacts in a homophilic manner in cell-cell interactions.

OBSOLETE. (Was not defined before being made obsolete).

OBSOLETE. (Was not defined before being made obsolete).

Combining with incidental electromagnetic radiation, particularly visible light, and transmitting the signal across the membrane by activating an associated G-protein; promotes the exchange of GDP for GTP on the alpha subunit of a heterotrimeric G-protein complex.

Binding to a protein C-terminus, the end of a peptide chain at which the 1-carboxyl function of a constituent amino acid is not attached in peptide linkage to another amino-acid residue.

OBSOLETE. The diazepam binding inhibitor is a 10kDa 86-residue polypeptide that acts as an endogenous ligand for a mitochondrial receptor (formerly regarded as a peripheral benzodiazepine binding site) in steroidogenic cells and regulates stimulation of steroidogenesis by tropic hormones. It also binds to the GABA-A receptor and modulates glucose-dependent insulin secretion and synthesis of acyl-CoA esters.

Catalysis of the reaction: 5'-adenylyl sulfate + H(2)O = AMP + 2 H(+) + sulfate.
