Kappapapillomavirus

Kappapapillomavirus is a genus of viruses, in the family Papillomaviridae[1]. Rabbits serve as natural hosts. There are currently only two species in this genus including the type species Kappapapillomavirus 2. Diseases associated with this genus include: cutaneous and mucosal lesions.[2][3]

Structure

Viruses in Kappapapillomavirus are non-enveloped, with icosahedral geometries, and T=7 symmetry. The diameter is around 52-55 nm. Genomes are circular, around 8kb in length. The genome codes for 6 proteins, and has 6, 8 open reading frames.[2]

Life cycle

Viral replication is nuclear. Entry into the host cell is achieved by attachment of the viral proteins to host receptors, which mediates endocytosis. Replication follows the dsDNA bidirectional replication model. DNA-templated transcription, with some alternative splicing mechanism is the method of transcription. The virus exits the host cell by nuclear envelope breakdown. Rabbits serve as the natural host. Transmission routes are contact.[2]
