Stimulates the hydrolysis and exchange of guanyl nucleotides by the GTPase Rap.

The chemical reactions involving phospholipids, any lipid containing phosphoric acid as a mono- or diester.

The formation from simpler components of phosphatidylethanolamine, any of a class of glycerophospholipids in which a phosphatidyl group is esterified to the hydroxyl group of ethanolamine.

peptide or protein carboxyl-terminal blocking

The directed movement of proteins into a cell or organelle.

Combining with erythropoietin to initiate a change in cell activity.

Catalysis of the release of an N-terminal dipeptide from a peptide comprising four or more residues, with broad specificity; also acts on dipeptidyl 2-naphthylamides.

Combining with growth hormone to initiate a change in cell activity.

Combining with an interferon to initiate a change in cell activity.

Combining with interferon-gamma to initiate a change in cell activity.

Combining with an interleukin to initiate a change in cell activity.

Combining with interleukin-1 to initiate a change in cell activity. Interleukin-1 is produced mainly by activated macrophages and is involved in the inflammatory response.

Interacting selectively with double-stranded DNA.

The chemical reactions involving fatty acids, aliphatic monocarboxylic acids liberated from naturally occurring fats and oils by hydrolysis.

interleukin-1, Type I, activating receptor activity

Interacting selectively with DNA in the Z form, i.e. a left-handed helix in which the phosphate backbone zigzags.

The formation from simpler components of a fatty acid, any of the aliphatic monocarboxylic acids that can be liberated by hydrolysis from naturally occurring fats and oils. Fatty acids are predominantly straight-chain acids of 4 to 24 carbon atoms, which may be saturated or unsaturated; branched fatty acids and hydroxy fatty acids also occur, and very long chain acids of over 30 carbons are found in waxes.

The process whereby the developmental fate of a cell becomes restricted such that it will develop into a myoblast cell.
