Summary: This gene encodes a type II transmembrane protein that is thought to have glycosyltransferase function. Mutations in this gene result in cobblestone lissencephaly. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, May 2013]
Expression: Ubiquitous expression in testis (RPKM 8.9), thyroid (RPKM 7.4) and 25 other tissues See more

RETINAL MANIFESTATIONS OF WALKER-WARBURG SYNDROME IN TWO SIBLINGS WITH RXYLT1 MUTATIONS.
Title: RETINAL MANIFESTATIONS OF WALKER-WARBURG SYNDROME IN TWO SIBLINGS WITH RXYLT1 MUTATIONS.
Fukutin, FKRP, and TMEM5 form a complex while maintaining each of their enzyme activities. Data showed that endogenous fukutin and FKRP enzyme activities coexist with TMEM5 enzyme activity, and suggest the possibility that formation of this enzyme complex may contribute to specific and prompt biosynthesis of glycans that are required for dystroglycan function.
Title: Cell endogenous activities of fukutin and FKRP coexist with the ribitol xylosyltransferase, TMEM5.
TMEM5 is a UDP-xylosyl transferase that elaborates the O-mannose glycan structure on alpha-dystroglycan. The authors demonstrate in a zebrafish model as well as in a human patient that defects in TMEM5 result in muscular dystrophy in combination with abnormal brain development.
Title: The functional O-mannose glycan on α-dystroglycan contains a phospho-ribitol primed for matriglycan addition.
TMEM5 acts as a UDP-d-xylose:ribitol-5-phosphate beta1,4-xylosyltransferase in the biosynthetic pathway of O-mannosyl glycan.
Title: The Muscular Dystrophy Gene TMEM5 Encodes a Ribitol β1,4-Xylosyltransferase Required for the Functional Glycosylation of Dystroglycan.
TMEM5 mutations were frequently associated with gonadal dysgenesis and neural tube defects, and ISPD mutations were frequently associated with brain vascular anomalies.

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.

Status: REVIEWED

Description

Transcript Variant: This variant (2) differs in the 5' UTR and has multiple coding region differences, compared to variant 1. These differences cause translation initiation at a downstream AUG and result in an isoform (2) with a shorter N-terminus, compared to isoform 1.
