Protein attributes

Sequence length	448 AA.
Sequence status	Complete.
Protein existence	Evidence at transcript level

General annotation (Comments)

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