• Eukaryotic protein O-mannosyltransferases (Pmts) are divided into three subfamilies (1, 2 and 4).
• The filamentous fungus Aspergillus nidulans has three Pmts, one from each subfamily.
• PmtA, PmtB and PmtC form heterodimers in all pairwise combinations.
• PmtC (subfamily 4) forms homodimers.
Eukaryotic protein O-mannosyltransferases (Pmts) are divided into three subfamilies (Pmt1, Pmt2, and Pmt4) and activity of Pmts in yeasts and animals requires assembly into complexes. In Saccharomyces cerevisiae, Pmt1 and Pmt2 form a heteromeric complex and Pmt 4 forms a homomeric complex. The filamentous fungus Aspergillus nidulans has three Pmts: PmtA (subfamily 2), PmtB (subfamily 1), and PmtC (subfamily 4). In this study we show that A. nidulans Pmts form heteromeric complexes in all possible pairwise combinations and that PmtC forms homomeric complexes. We also show that MsbA, an ortholog of a Pmt4-modified protein, is not modified by PmtC.
