COP9 signalosome complex subunit 3 is a protein that in humans is encoded by the COPS3 gene.
The protein encoded by this gene possesses kinase activity that phosphorylates regulators involved in signal transduction. It phosphorylates I-kappa-B-alpha, p105, and c-Jun. It acts as a docking site for complex-mediated phosphorylation. The gene is located within the Smith-Magenis syndrome region on chromosome 17.
Famous quotes containing the word complex:
“What we do is as American as lynch mobs. America has always been a complex place.”
—Jerry Garcia (1942–1995)
