Summary: Predicted to enable serine C-palmitoyltransferase activity. Predicted to be involved in ceramide biosynthetic process; regulation of fat cell apoptotic process; and sphingosine biosynthetic process. Predicted to act upstream of or within positive regulation of lipophagy; sphinganine biosynthetic process; and sphingomyelin biosynthetic process. Predicted to be located in endoplasmic reticulum membrane. Predicted to be part of serine palmitoyltransferase complex. Predicted to be active in endoplasmic reticulum.

What's a GeneRIF?

Data suggest that expression of enzymes involved in sphingolipid metabolism in skeletal muscle are regulated by dietary factors; here, caloric restriction down-regulates expression of Spt1 and Spt2 but up-regulates ceramide synthases (Cers1, Cers2).
Title: Modulation of sphingolipid metabolism with calorie restriction enhances insulin action in skeletal muscle.
sustained loss/reduction in SPT expression/activity promotes greater partitioning of palmitate towards diacylglycerol) synthesis, which impacts negatively upon insulin receptor substrate1-directed insulin signalling.
Title: Modulating serine palmitoyl transferase (SPT) expression and activity unveils a crucial role in lipid-induced insulin resistance in rat skeletal muscle cells.
marked upregulation of expression of both SPT subunits in actively proliferating cells in balloon-injured vessels(serine palmitoyltransferase 1)(serine palmitoyltransferase 2)
Title: Increased expression of serine palmitoyltransferase (SPT) in balloon-injured rat carotid artery.

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.
