Detection of Human Skp2 by Western Blot. Western blot shows lysates of 293T human embryonic kidney cell line, HeLa human cervical epithelial carcinoma cell line, Jurkat human acute T cell leukemia cell line, and U2OS human osteosarcoma cell line. PVDF membrane was probed with 2 µg/mL of Mouse Anti-Human Skp2 Monoclonal Antibody (Catalog # MAB6817) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). Specific bands were detected for Skp2 at approximately 45 and 48 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Skp2 (S-phase kinase-associated protein 2) is a 45-49 kDa cyclin A- and CDK2-associated phosphoprotein within the FBXL (F-box/LRR) family of ubiquitin ligases, designated FBXL1. Skp2 contains an F-box domain (amino acids (aa) 94-140) and 8 leucine-rich repeats (LRR) between aa 180 and 403. Isoforms of 424 and 410 aa, designated a and b, respectively, diverge after aa 354. As a component of the SCF (SKP1-Cul1-F-box) complex, Skp2 phosphorylation is required for degradation of CDK inhibitors such as p27/Kip1 and progression from G1 to S phases of the cell cycle. Deregulation in cancer promotes cell cycle progression and cancer growth. Within the region used as an immunogen, human Skp2 shares 84% aa sequence identity with mouse and rat Skp2.
