calcium-dependent protein serine/threonine phosphatase complex

A heterodimeric calcium ion and calmodulin dependent protein phosphatase composed of catalytic and regulatory subunits; the regulatory subunit is very similar in sequence to calmodulin.

Increases the activity of a protein kinase, an enzyme which phosphorylates a protein.

The processes by which a protein is transported to, or maintained in, basal regions of the cell.

Complex that possesses casein kinase activity, found in nearly every subcellular compartment. Protein kinase CK2 complexes are usually tetramers of two alpha and two beta subunits, and can phosphorylate many protein substrates in addition to casein.

protein tyrosine kinase activator activity

Increases the activity of a protein tyrosine kinase, an enzyme which phosphorylates a tyrosyl phenolic group on a protein.

The processes by which a protein is transported to, or maintained in, apical regions of the cell.

transmembrane receptor protein tyrosine kinase activator activity

DNA-dependent protein kinase, DNA-end-binding complex

A large protein complex which is involved in the repair of DNA double-strand breaks and V(D)J recombination events. In mammals, it consists of the DNA-dependent protein kinase catalytic subunit (DNA-PKcs), the DNA end-binding heterodimer, Ku, the nuclear phosphoprotein XRCC4 and DNA ligase IV.

Uptake of cholesterol into the blood by absorption from the small intestine.

Catalysis of the movement of phospholipids from one membrane face to the other ('flippase' activity), driven by the hydrolysis of ATP.

Catalysis of the reaction: S-adenosyl-L-homocysteine + H2O = adenosine + L-homocysteine.

Catalysis of the reaction: S-adenosyl-L-methionine = (5-deoxy-5-adenosyl)(3-aminopropyl) methylsulfonium salt + CO2.

Catalysis of the reaction: ATP = 3',5'-cyclic AMP + diphosphate.

Catalysis of the reaction: ATP + AMP = ADP + ADP.

Interacting selectively with eukaryotic initiation factor 4E, a polypeptide factor involved in the initiation of ribosome-mediated translation.
