CC -!- FUNCTION: Plays a role in the inhibition of host immune response within
CC the nucleus. Interacts with cellular nucleosomes and immobilizes the
CC host immune danger signal HMGB1 on chromatin. In turn, prevents HMGB1
CC release out of the cell and thus decreases inflammation. Also plays a
CC role in the wrapping and condensation of the viral DNA. May also
CC promote viral genome import into the nucleus. {ECO:0000255|HAMAP-
CC Rule:MF_04056}.
CC -!- SUBUNIT: Interacts with the core-capsid bridging protein; this
CC interaction bridges the virus core to the capsid. Interacts with host
CC NPM1; this interaction might play a role in placing the pre-histone-
CC like nucleoprotein on the viral DNA or regulating viral gene
CC expression. Interacts with host HMGB1; this interaction inhibits host
CC immune response. {ECO:0000255|HAMAP-Rule:MF_04056}.
CC -!- SUBCELLULAR LOCATION: [Histone-like nucleoprotein]: Virion
CC {ECO:0000255|HAMAP-Rule:MF_04056}. Note=Located inside the capsid in
CC association with the viral DNA (core). Present in about 1070 copies per
CC virion. {ECO:0000255|HAMAP-Rule:MF_04056}.
CC -!- SUBCELLULAR LOCATION: [Pre-histone-like nucleoprotein]: Host nucleus,
CC host nucleolus {ECO:0000255|HAMAP-Rule:MF_04056}.
CC -!- INDUCTION: Expressed in the late phase of the viral replicative cycle.
CC {ECO:0000255|HAMAP-Rule:MF_04056}.
CC -!- PTM: Cleaved near the N-terminus by the viral protease during virion
CC maturation to form the mature protein. {ECO:0000255|HAMAP-
CC Rule:MF_04056}.
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. {ECO:0000255|HAMAP-Rule:MF_04056}.
CC -!- SIMILARITY: Belongs to the adenoviridae histone-like nucleoprotein
CC family. {ECO:0000255|HAMAP-Rule:MF_04056, ECO:0000305}.
CC -!- SEQUENCE CAUTION:
