CC -!- FUNCTION: Catalyzes methylation of the shingoid base component of CC glucosylceramides (GluCers) at the C9-position. Sphingolipid C9- CC methylation requires 4,8-desaturated ceramides as substrates. CC Glucosylceramides play important roles in growth, differentiation CC and pathogenicity. The methyl group at the C9-position CC distinguishes fungal glucosylceramides from those of plants and CC animals, and may thus play a role in host-pathogen interactions CC enabling the host to recognize the fungal attack and initiate CC specific defense responses. Not necessary for vegetative growth at CC low temperatures, but plays a role in hyphal formation on solid CC medium. {ECO:0000269|PubMed:20019081}. CC -!- CATALYTIC ACTIVITY: S-adenosyl-L-methionine + a (4E,8E)-sphinga- CC 4,8-dienine ceramide = S-adenosyl-L-homocysteine + a 9-methyl- CC (4E,8E)-sphinga-4,8-dienine ceramide. CC {ECO:0000269|PubMed:20019081}. CC -!- PATHWAY: Lipid metabolism; sphingolipid metabolism. CC {ECO:0000305|PubMed:20019081}. CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000250|UniProtKB:C4R7Z3}; CC Multi-pass membrane protein {ECO:0000255}. CC -!- DISRUPTION PHENOTYPE: Produces only non-methylated CC glucosylceramides. Has a decreased hyphal growth rate. CC {ECO:0000269|PubMed:20019081}. CC -!- SIMILARITY: Belongs to the CFA/CMAS family. {ECO:0000305}.
