XYLT1 xylosyltransferase 1 [Homo sapiens (human)] - Gene

Summary

Official Symbol: XYLT1provided by HGNC
Official Full Name: xylosyltransferase 1provided by HGNC
Primary source: HGNC:HGNC:15516
See related: Ensembl:ENSG00000103489 MIM:608124; AllianceGenome:HGNC:15516
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Homo sapiens
Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo
Also known as: XT1; XTI; XT-I; DBQD2; XYLTI; PXYLT1; xylT-I
Summary: This locus encodes a xylosyltransferase enzyme. The encoded protein catalyzes transfer of UDP-xylose to serine residues of an acceptor protein substrate. This transfer reaction is necessary for biosynthesis of glycosaminoglycan chains. Mutations in this gene have been associated with increased severity of pseudoxanthoma elasticum.[provided by RefSeq, Nov 2009]
Expression: Ubiquitous expression in brain (RPKM 5.2), placenta (RPKM 4.3) and 24 other tissues See more

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
