Fig. 1.
Predicted structures of proteins MDIR1 through MDIR5; a splice variant of MDIR3 is included. Domain subtypes are indicated by contrasting colors (type I blue, type II black, type III green, type IVred). Amino acid identities among members of the same subtype are as follows: type II, 56–88%; type III, 68–90%; type IV, 72–88%. ITIM, immunoreceptor tyrosine-based inhibitory motif. ITIM-like motifs (YA[R/S]V), designated “itim”, are present in MDIR2. The dashed arrow designates a partial transcript
