Western blot analysis of E2F-1 was performed by loading 30 ug of HeLa (lane1), Hep G2 (lane2), A431 (lane3), U2OS (lane4), HCT 116 (lane5) cell tissue lysate using Novex® NuPAGE® 12 % Bis-Tris gel (NP0342BOX), XCell SureLock™ Electrophoresis System (EI0002), Novex® Sharp Pre-Stained Protein Standard (LC5800), and iBlot® Dry Blotting System (IB21001). Proteins were transferred to a nitrocellulose membrane and blocked with 5 % skim milk at 4°C overnight. E2F-1 was detected at ~47 and 60 kDa using E2F-1 Mouse Monoclonal Antibody (321400) at 1-3 ug/ml in 5 % skim milk for 3 hour at room temperature on a rocking platform. Goat Anti-Mouse - HRP Secondary Antibody (626520) at 1:4000 dilution was used and chemiluminescent detection was performed using Novex® ECL Chemiluminescent Substrate Reagent Kit (WP20005).

E2F1 is a member of the E2F family of transcription factors. The E2F family plays a crucial role in the control of cell cycle and action of tumor suppressor proteins and is also a target of the transforming proteins of small DNA tumor viruses. The E2F proteins contain several evolutionally conserved domains found in most members of the family. These domains include a DNA binding domain, a dimerization domain which determines interaction with the differentiation regulated transcription factor proteins (DP), a transactivation domain enriched in acidic amino acids, and a tumor suppressor protein association domain which is embedded within the transactivation domain. This protein and another 2 members, E2F2 and E2F3, have an additional cyclin binding domain. This protein binds preferentially to retinoblastoma protein pRB in a cell-cycle dependent manner. It can mediate both cell proliferation and p53-dependent/independent apoptosis.
