Summary: Enables sphingosine N-acyltransferase activity. Involved in ceramide biosynthetic process and regulation of lipid metabolic process. Acts upstream of or within sphingolipid biosynthetic process. Predicted to be located in endoplasmic reticulum. Is expressed in cerebral cortex; limb; liver; neural tube; and skin. Orthologous to human CERS2 (ceramide synthase 2). [provided by Alliance of Genome Resources, Nov 2024]

Deletion of CerS2 strongly reduced very long-chain ceramides (Cer24:0, 24:1) but concomitantly increased long-chain ceramides and sphinganine in plasma and colon tissue. In naive CerS2(-/-) mice, the expression of tight junction proteins including ZO-1 was almost completely lost in the colon epithelium, leading to increased membrane permeability.

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.
