GAUT12 plays a crucial role in pectin assembly and/or distribution, as well as in the synthesis of secondary wall glucuronoxylan. This protein is likely involved in the synthesis of the glycosyl sequence at the glucuronoxylan reducing end. It may also participate in the synthesis of a complex glycan primer for xylan synthesis.
Gene References Into Functions
IRX8 influences the levels of glucuronoxylan and homogalacturonan in higher plants, acting as a vital link between the xylan polymer and the secondary cell wall matrix. It directly impacts secondary cell wall integrity. [IRX8] [irregular xylem8] PMID: 17237350
Golgi apparatus membrane; Single-pass type II membrane protein.
Tissue Specificity
Highly expressed in stems. Detected in roots, inflorescences, siliques, and leaves. Expressed in cells undergoing secondary wall thickening, including interfascicular fibers and primary and secondary xylem.
