RESUMO
The proteins encoded by the open reading frames of papillomavirus genomes and the minor polypeptides detected in purified virions are still poorly defined. We show here by its expression in Escherichia coli that the open reading frame L2 of human papillomavirus type 1a codes for a minor structural protein of Mr 76,000. Antisera raised against a truncated L2-beta-galactosidase fusion protein in which the conserved N-terminal region of L2 is missing are type specific for human papillomavirus type 1 virions and are reactive at high dilutions. Expression of the L2-encoded type-specific antigens thus provides a powerful new tool for the identification of papillomaviruses.
