Figure 2. Predicted compatibility of bat-borne morbillivirus RBPs with human SLAMF1.
(A) MeV-RBP bound to SLAMF1 (PDB 3ALW) and homology modeling of the RBP from MBaMV and PBZ-1381. Models were made in SWISS-MODEL using 3ALW as template. RMSD values were 0.167 for MBaMV RBP and 0.143 for PBZ-1381 RBP. (B) Sequence alignments of the RBP from MeV, MBaMV, and PBZ-1381. Alignments were conducted using Clustal Omega with residue positions in reference to the PBZ-1381 RBP. Coloration depicts modeled interactions between each respective RBP and marmoset SLAMF1: Orange = occluded residue; Blue = hydrogen bond; Red = salt-bridge; Purple = hydrogen bond and salt bridge. Molecular interfaces were determined using PDBePISA. An asterisk (*) denotes a position in PBZ-1381 RBP in which the point mutation N503D could putatively confer usage of human/marmoset SLAMF1.
