Summary: This gene encodes a protein that belongs to the TLC (TRAM, LAG1 and CLN8 homology domains) family of proteins. The encoded protein functions in the synthesis of ceramide, a lipid molecule that is involved in a several cellular signaling pathways. Alternate splicing results in multiple transcript variants.

Studied the role of ceramide synthase 5 (LASS5 or CERS5) gene in atherosclerosis. Downregulation of LASS5 by siRNA was found to attenuate ceramide production and increase expression of some AMPK target genes in HUVEC. Found that LASS5 was involved in negative regulation of atherosclerosis-related genes, such as AMPK-alpha.

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.

RNA

NR_104035.3 RNA Sequence

Status: REVIEWED

Description

Transcript Variant: This variant (3) lacks one internal exon and contains one alternate exon compared to variant 1. This variant is represented as non-coding because the use of the 5'-most translational start codon, as used in variant 1, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
