CC -!- FUNCTION: Plays a central role in virus morphogenesis and assembly.
CC Acts as a viroporin and self-assembles in host membranes forming
CC pentameric protein-lipid pores that allow ion transport. Also plays a
CC role in the induction of apoptosis. {ECO:0000255|HAMAP-Rule:MF_04204}.
CC -!- SUBUNIT: Homopentamer. Interacts with membrane protein M in the budding
CC compartment of the host cell, which is located between endoplasmic
CC reticulum and the Golgi complex. Interacts with Nucleoprotein.
CC {ECO:0000255|HAMAP-Rule:MF_04204}.
CC -!- SUBCELLULAR LOCATION: Host Golgi apparatus membrane {ECO:0000255|HAMAP-
CC Rule:MF_04204}; Single-pass type III membrane protein
CC {ECO:0000255|HAMAP-Rule:MF_04204}. Note=The cytoplasmic tail functions
CC as a Golgi complex-targeting signal. {ECO:0000255|HAMAP-Rule:MF_04204}.
CC -!- SIMILARITY: Belongs to the betacoronaviruses E protein family.
CC {ECO:0000255|HAMAP-Rule:MF_04204}.
