CC -!- FUNCTION: Mannosyl transferase (ManT) required for the biosynthesis of
CC mannose-carrying glycosylinositol phosphorylceramides (GIPCs)
CC (PubMed:27895225). Maybe involved in cell-cell adhesion that maintains
CC the integrity of organs by providing mechanical strength and
CC facilitating the movement of metabolites throughout the plant during
CC development (PubMed:16045474). Prevents abscisic acid- (ABA-) mediated
CC effects on development (e.g. cell size, flowering time, senescence).
CC Probably implicated in beta-(1,4)-galactan biosynthesis thus being a
CC cell-wall synthesis-related (CWSR) protein (PubMed:17426055,
CC PubMed:20687615). {ECO:0000250, ECO:0000269|PubMed:16045474,
CC ECO:0000269|PubMed:17426055, ECO:0000269|PubMed:27895225,
CC ECO:0000303|PubMed:20687615}.
CC -!- COFACTOR:
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC Evidence={ECO:0000250|UniProtKB:Q9ES89};
CC -!- PATHWAY: Protein modification; protein glycosylation. {ECO:0000305}.
CC -!- PATHWAY: Sphingolipid metabolism. {ECO:0000269|PubMed:27895225}.
CC -!- SUBCELLULAR LOCATION: Golgi apparatus membrane
CC {ECO:0000269|PubMed:17426055, ECO:0000269|PubMed:27895225}; Single-pass
CC type II membrane protein {ECO:0000255}.
CC -!- TISSUE SPECIFICITY: Expressed in leaves, roots, stem, and flowers.
CC {ECO:0000269|PubMed:17426055}.
CC -!- DISRUPTION PHENOTYPE: Disturbed production of mannose-carrying
CC glycosylinositol phosphorylceramides (GIPCs) in gmt1-3
CC (PubMed:27895225). Dwarf plants exhibiting a constitutive
CC hypersensitive response characterized by elevated salicylic acid (SA)
CC and hydrogen peroxide H(2)O(2) levels (PubMed:27895225). Reduced
CC cellulose content, but increased lignin accumulation in cell walls
CC (PubMed:27895225). In epc1-1, strong growth reduction, mechanical
CC fragility, defects in vascular formation and enhanced secondary growth
CC in hypocotyl tissues probably due to abnormal cell-cell adhesion
CC properties in hypocotyl, cotyledon and cortical parenchyma tissues
CC (PubMed:16045474). Ectopic callose deposition, increased glucose level,
CC but reduced level of galactose in cell walls (PubMed:16045474). In
CC epc1-2, dwarf, reduced cell size, defective root hair development,
CC delayed flowering, early senescence, and hypersensitivity to abscisic
CC acid (ABA) during germination and root elongation (PubMed:17426055).
CC Reduced levels of beta-(1,4)-galactan (PubMed:17426055).
CC {ECO:0000269|PubMed:16045474, ECO:0000269|PubMed:17426055,
CC ECO:0000269|PubMed:27895225}.
CC -!- MISCELLANEOUS: Initially thought to be involved in cell-cell adhesion
CC (PubMed:16045474), this function could not be confirmed
CC (PubMed:17426055). {ECO:0000305|PubMed:17426055}.
CC -!- SIMILARITY: Belongs to the glycosyltransferase 64 family.
CC {ECO:0000305}.
