Background: JAB1

JAB1 (Jun activation domain binding protein-1), also called COPS5 or CSN5 (COP9 signalosome-5), is a 334 amino acid (aa), 38 kDa protein that is a subunit of the COP9 signalosome complex. It mediates cytosolic translocation of the cell cycle inhibitory protein, CDKN1B/p27Kip1, for degradation, thus promoting proliferation. It is widely expressed, especially in proliferating cells and up-regulates granulopoiesis when overexpressed. Within the region used as an immunogen, human JAB1 shares 99% aa identity with mouse and rat JAB1. A 379 aa isoform contains 93 alternate aa in place of the N-terminal 48 aa of the 334 aa form.
