CC   -!- FUNCTION: Inner envelope protein involved, through its interaction with
CC       host dynein, in the intracellular microtubule-dependent transport of
CC       viral capsid toward viral factories (By similarity). Seems to induce
CC       caspase-3 activation and apoptosis (By similarity). Plays a role in
CC       virion morphogenesis by recruiting and transforming the host ER
CC       membranes into the precursors of the viral envelope (By similarity).
CC       Involved in virus attachment to the host cell (By similarity).
CC       {ECO:0000250|UniProtKB:Q65194}.
CC   -!- SUBUNIT: Interacts with the host light chain cytoplasmic dynein DYNLL1;
CC       this interaction is critical for intracellular microtubule-dependent
CC       virus transport toward viral factories. {ECO:0000250|UniProtKB:Q65194}.
CC   -!- SUBCELLULAR LOCATION: Virion membrane {ECO:0000250|UniProtKB:Q65194};
CC       Single-pass membrane protein {ECO:0000250|UniProtKB:Q65194}. Host
CC       cytoplasm, host cytoskeleton {ECO:0000250|UniProtKB:Q65194}. Host
CC       endoplasmic reticulum membrane {ECO:0000250|UniProtKB:Q65194}.
CC       Note=Detected mainly on membrane-like structures within viral
CC       factories. Present in mature extracellular virions. Host DYNLL1 and
CC       viral p54 interact at the microtubular organizing center (By
CC       similarity). Found in the inner envelope of the virus (By similarity).
CC       {ECO:0000250|UniProtKB:Q65194}.
CC   -!- INDUCTION: Expressed in the late phase of the viral replicative cycle.
CC       {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the asfivirus envelope protein p54 family.
CC       {ECO:0000305}.
