Background: E2F-2 (viral E2-associated factor 2) is a 50 55 kDa member of the E2F/DP family of transcription factors. It is principally expressed by placenta, and forms a DNA activating E2F heterodimeric complex with DP-1 or-2. This complex, when active, promotes cell cycle progression. In quiescent cells, association with the retinoblastoma-tumor suppressor gene product termed pRB suppresses its activity. Human E2F 2 is 437 amino acids (aa) in length and contains a CDK2 binding region (aa 65 105), a DNA binding domain (aa 107 196), a dimerization segment (aa 197 289), a transactivation region (aa 359 437), and a pRB binding domain (aa 410 427). There are two potential alternate start sites at Met197 and Met342, and one splice variant that shows a two aa substitution for aa 349 437. Over aa 308 437, human E2F-2 is 72% aa identical to mouse E2F-2.
Bio Acitivity: Not validated for activity
Sequence: Ala 65-Asn 437
Purity: > 95% as determined by reducing SDS-PAGE.
Formulation: Lyophilized from sterile PBS, pH 7.4.
Normally 5%-8% trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the printed manual.
Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.5 mg/mL. Concentration is measured by UV-Vis.
Endotoxin: < 10 EU/mg of the protein as determined by the LAL method.
Calculated MW: 40.9 kDa
Observed MW: 55 kDa
