M45 is a 97-kDa virion-associated protein encoded by mouse cytomegalovirus (MCMV) (Krause et al., 2014, Journal of Virology, 88(17), 9963–9975; Rawlinson et al., 1996, Journal of Virology, 70(10), 8833–8849).
Murine cytomegalovirus m152 is an ER resident type I transmembrane protein that retains MHC I and NKG2D ligands Rae-1 proteins in the ER and thus aids virally infected cells in evading NK and T cells.
V-set and transmembrane domain containing 1 (VSTM1) encodes two main splicing isoforms, VSTM1-v1 and VSTM1-v2 (Guo, Cell Immunol 2012, 278: 136–142; Steevels, J Immunol. 2010;184:4741–8).
Killer cell immunoglobulin-like receptors (KIRs) are transmembrane glycoproteins expressed by <1-8% NK cells and subsets of CD8+ T cells (Melero et al., 1994, The Journal of Immunology, 152(4)).
Human activating receptor natural-killer group 2, member D (NKG2D) is a 35 kDa type II transmembrane glycoprotein and a part of CD94/NKG2 family of C-type lectin-like receptors
Murine cytomegalovirus immediate-early 1 (IE1, pp89, m123) is one of the first proteins expressed during productive (lytic) infection as well as during reactivation from the latency.
