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 (By similarity). Activates the host
CC NLRP3 inflammasome, leading to IL-1beta overproduction.

CC ECO:0000269|PubMed:26331680}.
CC -!- SUBUNIT: Homopentamer (PubMed:22819936). Interacts with membrane
CC protein M in the budding compartment of the host cell, which is located
CC between endoplasmic reticulum and the Golgi complex (PubMed:19322648).
CC Interacts with Nucleoprotein (PubMed:24766657). Interacts with the
CC accessory proteins 3a and 7a. Interacts (via C-terminus) with human
CC PALS1 (via PDZ domain); this inhibits the interaction between human
CC PALS1 and human CRB3, and causes delayed tight junction formation and
CC defective cell polarity (PubMed:20861307). {ECO:0000255|HAMAP-
