CC -!- FUNCTION: Acts as a CD40 functional homolog to prevent apoptosis of
CC infected B-lymphocytes and drive their proliferation. Functions as a
CC constitutively active tumor necrosis factor receptor that induces the
CC activation of several signaling pathways, including those of the NF-
CC kappa-B family. LMP1 signaling leads to up-regulation of antiapoptotic
CC proteins and provide growth signals in latently infected cells.
CC Interacts with host UBE2I and subsequently affects the sumoylation
CC state of several cellular proteins. For example, induces the
CC sumoylation of host IRF7 thereby limiting its transcriptional activity
CC and modulating the activation of innate immune responses. Inhibits also
CC host IFN-alpha-stimulated STAT2 nuclear translocation and interferon-
CC stimulated response element transcriptional activity by interacting
CC with and inhibiting host TYK2. {ECO:0000250|UniProtKB:P03230}.
CC -!- SUBUNIT: Interacts (via PXQXT motif) with host tumor necrosis factor
CC receptor-associated factor (TRAF) proteins TRAF1, TRAF2, TRAF3 and
CC TRAF5. Interacts with human protein ZMYND11; leading to negatively
CC regulate NF-kappa-B activation. Interacts with host UBE2I; this
CC interaction induces the sumoylation of various cellular proteins.
CC Interacts with host IRF7. Interacts with host TYK2.
CC {ECO:0000250|UniProtKB:P03230}.
CC -!- SUBCELLULAR LOCATION: Host cell membrane {ECO:0000250}; Multi-pass
CC membrane protein {ECO:0000250}.
CC -!- DOMAIN: Two regions, C-terminal-activating region 1 (CTAR1) and CTAR2,
CC have been identified within the cytoplasmic carboxy terminal domain
CC that activates NF-kappa-B. {ECO:0000250}.
CC -!- PTM: Ubiquitinated on the N-terminus. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the herpesviridae LMP-1 family. {ECO:0000305}.
