    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

    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.
