NCIt definition : Human E1B protein (175 aa, 20 kDa) protein is encoded by the human adenovirus 2 (HadV-2)
gene. This protein is transcribed by the E1B region of the HadV-2 gene, which is involved
in the regulation of E1B protein levels. This protein is an inhibitor of apoptosis
induced by TNF or FAS pathways, as well as p53-mediated apoptosis. Without E1B function,
virus production is compromised due to the premature death of the host cell.;
