Glycosyltransferase that plays an important role in infection-related morphogenesis and pathogenesis (PubMed:31484736). Involved in stress tolerance and hyphal hydrophobicity via its regulation of the expression of nydrophobin MPG1 (PubMed:31484736). May regulate growth, pathogenicity, and cell wall integrity (CWI) through glycosylation of heat shock protein SSB1, and other (unidentified) substrates may contribute to conidiation (PubMed:31484736). Candidate proteins as potential substrates of GT2 include several heat shock proteins (SSB1/MGG_02503, MGG_06759 and MGG_06958), two coiled-coil domain-containing proteins (MGG_04321 and MGG_09571), aminopeptidase 2 (MGG_16472), and a nuclease domain-containing protein (MGG_12646) (PubMed:31484736). The conserved DxD and QxxRW domains are necessary for the full function. Results in impairment of vegetative growth, conidiation, stress response, hyphal appressorium-mediated penetration, and pathogenicity (PubMed:31484736). Leads to altered glycoproteins during conidiation (PubMed:31484736). Significantly reduces the expression levels of hydropgobin MPG1 (PubMed:31484736). Belongs to the GT2 glycosyltransferase family.
