Schematic of the domains in shell matrix proteins identified in this study. CC: coiled coil; PL: pectin lyase-like; Vir28: variable surface protein Vir28; TI: trypsin inhibitor-like cysteine-rich domain; NAD(P): NAD(P)-binding Rossmann-fold domains; ABC-TS: ABC-type transport system; TR: transmembrane region; PAMG: Pneumovirinae attachment membrane glycoprotein G; SOD: copper/zinc superoxide dismutase; SapB: saposin B domains; Ac: Actin; I29: cathepsin propeptide inhibitor domain; and Papain: papain family cysteine protease
