CD46 is a cellular receptor for species D human adenovirus.

ABSTRACT: Human adenovirus species D (HAdV-D) contains two-thirds of all known HAdV types (116 in total) and is important as a vector in clinical applications. However, the broad tropism exhibited by several HAdV-D types poses challenges for their use as targeted gene delivery vectors. Since adenoviral tropism is largely governed by receptor usage, we aimed to determine the relative importance of known adenovirus receptors in mediating infection by different HAdV-D types. Here, we generated A549 single-cell CRISPR/Cas9 knockout clones of desmoglein 2 (DSG2), CD46, the coxsackievirus and adenovirus receptor (CAR), and cytidine monophosphate N-acetylneuraminic acid synthetase (CMAS; needed for biosynthesis of sialic acid-containing glycans), and assessed their relative importance for infection by 18 d
