General annotation (Comments)

Function

Acts as a CD40 functional homolog to prevent apoptosis of infected B-lymphocytes and drive their proliferation. Functions as a constitutively active tumor necrosis factor receptor that induces the activation of several signaling pathways, including those of the nuclear factor-kappa-B family. LMP1 signaling leads to up-regulation of antiapoptotic proteins and provide growth signals in latently infected cells. It is a short-lived protein probably degraded by the proteasome.

Subunit structure

Interacts (via PXQXT motif) with host tumor necrosis factor receptor-associated factor (TRAF) proteins TRAF1, TRAF2, TRAF3 and TRAF5.

Subcellular location

Host cell membrane; Multi-pass membrane protein Ref.8.

Domain

Two regions, C-terminal-activating region 1 (CTAR1) and CTAR2, have been identified within the cytoplasmic carboxy terminal domain that activates NF-kappa-B. Ref.7

Post-translational modification

Ubiquitinated on the N-terminus. Ref.8

Sequence similarities

Belongs to the herpesviridae LMP-1 family.
