Summary
Ganglioside GM3 is known to participate in the induction of cell differentiation, modulation of cell proliferation, maintenance of fibroblast morphology, signal transduction, and integrin-mediated cell adhesion. The protein encoded by this gene is a type II membrane protein which catalyzes the formation of GM3 using lactosylceramide as the substrate. The encoded protein is a member of glycosyltransferase family 29 and may be localized to the Golgi apparatus. Mutation in this gene has been associated with Amish infantile epilepsy syndrome. Transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

  5. HEK-293T clones permanently expressing HaloTag-ST3GAL5 carrying each of the five variants were assessed by quantitative PCR, flow cytometry, western blotting and confocal microscopy. Compared with the very mild phenotype of st3gal5 KO mouse models, the results suggest that unknown mechanisms, in addition to the lack of a-b-c-series gangliosides, contribute to the syndrome.

  6. Since the nineties, mice lacking genes for single glycosyltransferases involved in ganglioside biosynthesis, including ST3GAL5 and B4GALNT1, were created and studied. The resulting phenotypes were frequently mild or very mild, so double knock-out animals were created to effectively study the function of gangliosides

  7. While no differences in clinical characteristics were detected in patients possessing the functional promoter haplotypes of ST3GAL5, exophthalmic values were significantly lower in patients with the ST8SIA1 haplotype, which showed a significant increase in promoter activity

  8. These cases broaden the phenotypic and genetic spectrum of GM3 synthase deficiency due to ST3GAL5 variants. Patients with intellectual disability or furthermore presenting with Rett-like phenotype should be suspected of GM3 synthase deficiency, a disorder of ganglioside biosynthesis.

  9. Data suggest that ganglioside glycosyltransferases ST3GAL5, ST8SIA1, and B4GALNT1 are S-acylated at conserved cysteine residues located close to cytoplasmic border of their transmembrane domains; ST3Gal-II is acylated at conserved cysteine residue in N-terminal cytoplasmic tail; for B4GALNT1 and ST3Gal-II, dimer formation controls their S-acylation status.

  10. Studied the miRNA expression in human hepatocellular carcinoma cell lines; 13 differentially expressed miRNAs were identified between MHCC97-H and MHCC97-L cells; and the same results were found in clinical samples. Found that ST3GAL5 was the direct target of miR-26a, miR-548l and miR-34a.

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.
