Structural highlights
Function
SPIKE_ADE1P Forms spikes that protrude from each vertex of the icosahedral capsid. Interacts with host receptor CD46 to provide virion initial attachment to target cell. Fiber proteins are shed during virus entry, when virus is still at the cell surface.
Publication Abstract from PubMed
The main limitation of oncolytic vectors is neutralization by blood components, which prevents intratumoral administration to patients. Enadenotucirev, a chimeric HAdV-11p/HAdV-3 adenovirus identified by bio-selection, is a low seroprevalence vector active against a broad range of human carcinoma cell lines. At this stage, there's still some uncertainty about tropism and primary receptor utilization by HAdV-11. However, this information is very important, as it has a direct influence on the effectiveness of HAdV-11-based vectors. The aim of this work is to determine which of the two receptors, DSG2 and CD46, is involved in the attachment of the virus to the host, and what role they play in the early stages of infection.
