Structural variations in species B adenovirus fibers impact CD46 association.
A majority of species B adenoviruses (Ads) use CD46 as their primary receptor; however, the precise mechanisms involved in the binding of different Ad types to CD46 have not been resolved. Although previous studies indicate close similarities between two members of species B2 Ads in their usage of CD46, our current investigations revealed a surprisingly low CD46 binding affinity of the species ...
متن کاملThe human membrane cofactor CD46 is a receptor for species B adenovirus serotype 3.
Many human adenovirus (Ad) serotypes use the coxsackie B virus-Ad receptor (CAR). Recently, CD46 was suggested to be a receptor of species B Ad serotype 11 (Ad11), Ad14, Ad16, Ad21, Ad35, and Ad50. Using Sindbis virus-mediated cDNA library expression, we identify here the membrane cofactor protein CD46 as a surface receptor of species B Ad3. All four major CD46 transcripts and one minor CD46 tr...
متن کاملStructure of adenovirus type 21 knob in complex with CD46 reveals key differences in receptor contacts among species B adenoviruses.
The complement regulation protein CD46 is the primary attachment receptor for most species B adenoviruses (Ads). However, significant variability exists in sequence and structure among species B Ads in the CD46-binding regions, correlating with differences in affinity. Here, we report a structure-function analysis of the interaction of the species B Ad21 knob with the two N-terminal repeats SCR...
متن کاملThe three species B Adenovirus serotypes
We recently characterized the domains of the human cofactor protein CD46 involved in binding species B2 adenovirus (Ad) serotype 35. Here, the CD46 binding determinants are mapped for the species B1 Ad serotypes 3 and 7 and for the species B2 Ad11. Ad3, 7 and 11 bound and transduced CD46-positive rodent BHK cells at levels similar to Ad35. By using antibody-blocking experiments, hybrid CD46-CD4...
متن کاملAdenovirus type 11 uses CD46 as a cellular receptor.
The 51 human adenovirus serotypes are divided into six species (A to F). Many adenoviruses use the coxsackie-adenovirus receptor (CAR) for attachment to host cells in vitro. Species B adenoviruses do not compete with CAR-binding serotypes for binding to host cells, and it has been suggested that species B adenoviruses use a receptor other than CAR. Species B adenoviruses mainly cause disease in...
