Amino acids are depicted by single letter IUPAC abbreviations. Red indicates amino acids conserved in all sequences. Black inverted triangles represent the presence and location of mucin-like domains; sequences lacking a triangle do not have mucin-like domains. Exemplar mucin-like repeats with subscripts denoting the number of tandem repeats are in the box to the left of sequence names. “≥” indicates that only a partial-length repetitive region is known. Species names are abbreviated. Full species names and GenBank accession numbers are in Table 1.
