CC   -!- FUNCTION: Scaffold protein which forms a transitory spherical honeycomb
CC       lattice providing curvature and rigidity to the convex membrane of
CC       crescent and immature virions (IV). This association occurs
CC       concomitantly with viral membrane formation. Targeted by the drug
CC       rifampicin, which prevents the formation of this lattice, and hence
CC       virus morphogenesis. In the presence of rifampicin, irregularly shaped
CC       membranes that lack the honeycomb layer accumulate around areas of
CC       electron-dense viroplasm. This layer is lost from virions during
CC       maturation from IV to mature virion (MV), through the proteolysis of
CC       A17 N-terminus (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Homotrimer (By similarity). Self-assembles to form a layer.
CC       Interacts with A17 (via N-terminus); this interaction is necessary for
CC       D13 association with membranes (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Membrane; Peripheral membrane protein.
CC       Note=Associates transitorily with crescent and IV membranes.
CC       {ECO:0000250}.
CC   -!- MISCELLANEOUS: Displays structure similarities to capsid proteins.
CC   -!- SIMILARITY: Belongs to the poxviridae protein D13 family.
CC       {ECO:0000305}.
