CC -!- FUNCTION: Forms an icosahedral capsid with a T=7 symmetry and a 50 nm
CC diameter. The capsid is composed of 72 pentamers linked to each other
CC by disulfide bonds and associated with L2 proteins. Binds to heparan
CC sulfate proteoglycans on cell surface of basal layer keratinocytes to
CC provide initial virion attachment. This binding mediates a
CC conformational change in the virus capsid that facilitates efficient
CC infection. The virion enters the host cell via endocytosis. During
CC virus trafficking, L1 protein dissociates from the viral DNA and the
CC genomic DNA is released to the host nucleus. The virion assembly takes
CC place within the cell nucleus. Encapsulates the genomic DNA together
CC with protein L2. {ECO:0000255|HAMAP-Rule:MF_04002}.
CC -!- SUBUNIT: Self-assembles into homopentamers. The capsid has an
CC icosahedral symmetry and consists of 72 capsomers, with each capsomer
CC being a pentamer of L1. Interacts with the minor capsid protein L2;
CC this interaction is necessary for viral genome encapsidation. Interacts
CC with protein E2; this interaction enhances E2-dependent replication and
CC transcription activation. {ECO:0000255|HAMAP-Rule:MF_04002}.
CC -!- SUBCELLULAR LOCATION: Virion {ECO:0000255|HAMAP-Rule:MF_04002}. Host
CC nucleus {ECO:0000255|HAMAP-Rule:MF_04002}.
CC -!- SIMILARITY: Belongs to the papillomaviridae L1 protein family.
CC {ECO:0000255|HAMAP-Rule:MF_04002}.
