Diagram of the main features of representative members of the Ld130 protein family. The predicted signal and transmembrane (TM) domains are shown. Conserved cysteines (C) are indicated by the vertical dashed line intersecting the maps of each protein group. The consensus cleavage site (K/RXXK/R) along with the downstream conserved sequences are shown by the vertical arrow (↓). The predicted coiled-coil domains are indicated by the coil-like structure. Representations are not drawn to scale.
