Betapapillomavirus is a genus of viruses, in the family Papillomaviridae. (wikipedia.org)
HPVs2
Human papillomavirus (HPV) types from the beta genus (beta-HPVs) have been implicated in the development of skin cancer. (utmb.edu)
HPVs of the beta genera (ß-HPV) are risk factors for cutaneous squamous cell carcinoma (cSCC) and may be related to carcinomas originating in other cutaneous sites such as the vulva. (bvsalud.org)
They are grouped into multiple genera, but the viruses are highly host-species specific and tissue-restricted. (bvsalud.org)
Species2
There are six species in this genus. (wikipedia.org)
Six of the untyped strains clustered with sequences from species 7, 9, 10, 8,12 of γ genus. (biomedcentral.com)
Beta4
The E6 proteins of the beta-HPV type 5 (HPV5), -8, -20, -22, -38, -76, -92, and -96, as well as the alpha genus HPV HPV16, all degraded Bak or prevented its accumulation following UV treatment but did not degrade Bak constitutively. (utmb.edu)
In addition, when tested using HPV16 E6 (16E6) and 8E6 as representative E6 proteins from the alpha and beta genera, respectively, Bak degradation was dependent on the E3 ubiquitin ligase, E6AP. (utmb.edu)
Persistent infections of the skin with the human papillomavirus of genus beta (ß-HPV) in immunocompetent individuals are asymptomatic, but in immunosuppressed patients, ß-HPV infections exhibit much higher viral loads on the skin and are associated with an increased risk of skin cancer.
