CC -!- FUNCTION: [Pre-core protein X]: Interacts with the viral DNA and aids
CC in tightly condensing it within the capsid. Cleavage of pre-core
CC protein X may serve to partially relax this structure within the mature
CC virion prior to its entry into the nucleus (By similarity).
CC {ECO:0000250}.
CC -!- SUBUNIT: Interacts with the core-capsid bridging protein; this
CC interaction bridges the virus core to the capsid. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: [Pre-core protein X]: Host nucleus, host
CC nucleolus {ECO:0000250}. Note=Excluded from adenovirus DNA-binding
CC protein (DBP)-rich replication centers in adenovirus-infected cells.
CC -!- SUBCELLULAR LOCATION: [Core protein X]: Virion. Note=Located inside the
CC capsid in association with the viral DNA (core). Present in about 126-
CC 160 copies per virion. Excluded from adenovirus DNA-binding protein
CC (DBP)-rich replication centers in adenovirus-infected cells (By
CC similarity). {ECO:0000250}.
CC -!- INDUCTION: Expressed in the late phase of the viral replicative cycle.
CC -!- PTM: Cleaved by the viral protease during virion maturation to form the
CC mature protein. {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 core protein X family.
CC {ECO:0000305}.
