Coxsackie Virus And Adenovirus Receptor (CXADR)

CXADR is a type I membrane receptor for group B coxsackieviruses and subgroup C adenoviruses. Pseudogenes of this gene are found on chromosomes 15, 18, and 21. The deduced 365-amino acid human peptide has a calculated molecular mass of 39 kD and shares 83% sequence identity with the mouse homolog. Both peptides contain a potential leader sequence, transmembrane domains, 2 N-linked glycosylation sites, and 2 extracellular disulfide-bonded loops resembling the characteristic V and C2 domains of the immunoglobulins.transfection of CXADR or Cxadr into NIH 3T3 cells conferred susceptibility to infection by CVB3 and CVB4, resulting in 100- to 1000-fold higher virus titers following exposure than that found in nontransfected control cultures.
