—Alignment of amino acid sequences of the TM regions of human (Hs) FcRγ-associating LRC members and the predicted LRC members from Tasmanian devil (Sh), opossum (Md), and platypus (Oa). Attribution of opossum and platypus OSCAR, as well as devil GPVI is based on the results of phylogenetic analysis. Other opossum sequences are designated according to the gene position in the current version of the genome (fig. 6A). Identical and similar residues are shown by white letters on black background or black letters on gray background, respectively. Consensus (>50%) sequence is shown below. Asterisks indicate invariant residues.
