GXYLT1 pseudogene 1 (GXYLT1P1)

GXYLT1 pseudogene 1 (GXYLT1P1) is a non-coding pseudogene locus related to the functional GXYLT1 gene, which codes for glucoside xylosyltransferase 1, a glycosyltransferase that modifies Notch receptors through O-linked glycosylation[1][3]. Pseudogenes like GXYLT1P1 do not encode active proteins and are not considered drug targets. The functional GXYLT1 protein has clinical relevance in diseases like colorectal cancer, but the pseudogene GXYLT1P1 does not have documented biological functions or disease roles[6][3]. If a functional drug target is intended, the query should likely refer to glucoside xylosyltransferase 1 (GXYLT1), not its pseudogene.
