CC -!- FUNCTION: Probable O-acetyltransferase involved in the acetylation of
CC xylan during secondary wall biosynthesis. {ECO:0000269|PubMed:21673009,
CC ECO:0000269|PubMed:24019426}.
CC -!- SUBCELLULAR LOCATION: Golgi apparatus membrane
CC {ECO:0000269|PubMed:21673009}; Multi-pass membrane protein
CC {ECO:0000255}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=3;
CC Name=1;
CC IsoId=Q9FXG3-1; Sequence=Displayed;
CC Name=2;
CC IsoId=Q9FXG3-2; Sequence=VSP_057929;
CC Name=3;
CC IsoId=Q9FXG3-3; Sequence=VSP_057930, VSP_057931;
CC -!- TISSUE SPECIFICITY: Expressed in cells undergoing secondary wall
CC thickeningin a SND1-dependent manner, such as xylem cells and
CC interfascicular fibers. Mostly expressed in the middle and bottom parts
CC of the inflorescence stems (PubMed:21673009). Mainly observed in the
CC more mature parts of inflorescence stems, but present ubiquitously
CC (PubMed:21212300). {ECO:0000269|PubMed:21212300,
CC ECO:0000269|PubMed:21673009}.
CC -!- DISRUPTION PHENOTYPE: No visible phenotype on cell wall acetylation in
CC single mutant (PubMed:21212300). Severe growth phenotypes (e.g. dwarf
CC and abnormal flower organs) associated with reduction in the secondary
CC wall thickening and the stem mechanical strength in the quadruple
CC mutant rwa1 rwa2 rwa3 rwa4 and characterized by reduced xylan
CC acetylation and altered ratio of non-methylated to methylated
CC glucuronic acid side chains. Absence of interfascicular fibers and
CC xylem cells differentiation (PubMed:21673009, PubMed:24019426). The
CC double mutant rwa2 rwa4 and triple mutants rwa2 rwa3 rwa4, rwa1 rwa3
CC rwa4 and rwa1 rwa2 rwa4 are also dwarfs with abnormal morphology.
CC Altered O-acetylated xyloglucans (XyG) oligosaccharides (XyGOs)
CC composition (PubMed:24019426). {ECO:0000269|PubMed:21212300,
CC ECO:0000269|PubMed:21673009, ECO:0000269|PubMed:24019426}.
CC -!- SIMILARITY: Belongs to the PC-esterase family. CASD1 subfamily.
CC {ECO:0000305}.

CC Sequence=AAG10607.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
