CC   -!- FUNCTION: Forms spikes that protrude from each vertex of the
CC       icosahedral capsid. Interacts with host receptor CXCAR to provide
CC       virion initial attachment to target cell. Fiber proteins are shed
CC       during virus entry, when virus is still at the cell surface (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Homotrimer. Interacts with host receptor CXCAR. Interacts (via
CC       N-terminal tail region) with pentons (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000250}. Host nucleus {ECO:0000250}.
CC       Note=Anchored to the pentons, protrudes from the virion surface.
CC       {ECO:0000250}.
CC   -!- INDUCTION: Expressed in the late phase of the viral replicative cycle.
CC   -!- DOMAIN: The tail region anchors the fiber to penton base capsomers,
CC       whereas the shaft, built from several repeated motifs, allows the knob
CC       to protrude from the virion. {ECO:0000250}.
CC   -!- MISCELLANEOUS: All late proteins expressed from the major late promoter
CC       are produced by alternative splicing and alternative polyadenylation of
CC       the same gene giving rise to non-overlapping ORFs. A leader sequence is
CC       present in the N-terminus of all these mRNAs and is recognized by the
CC       viral shutoff protein to provide expression although conventional
CC       translation via ribosome scanning from the cap has been shut off in the
CC       host cell (By similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the adenoviridae fiber family. {ECO:0000305}.
