JAB1 Antibody [Unconjugated]

Western blot shows lysates of HepG2 human hepatocellular carcinoma cell line, PT18 mouse mast/basophil cell line, and L6 rat myoblast cell line. PVDF Membrane was probed with 1 µg/mL of Sheep Anti-Human/Mouse/Rat JAB1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6390) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for JAB1 at approximately 38 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background

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.
