Function
Ceramide synthase 2, also known as LAG1 longevity assurance homolog 2 or Tumor metastasis-suppressor gene 1 protein is an enzyme that in humans is encoded by the CERS2 gene. Ceramide synthase 2 is a ceramide synthase that catalyses the synthesis of very long acyl chain ceramides, including C20 and C26 ceramides. It is the most ubiquitously expressed of all CerS and has the broadest distribution in the human body. CerS2 was first identified in 2001. It contains the conserved TLC domain and Hox-like domain common to almost all CerS. Expression of CerS2 is transiently increased during periods of active myelination, suggesting that it is important for the synthesis of myelin sphingolipids. The lack of CerS2, as shown in knockout mice, induces the autophagy and activation of the unfolded protein response (UPR). These mice showed no decrease in overall ceramide level, but levels of sphinganine were elevated. They also developed severe liver disease, but there was no observable change in the kidneys. The CerS2 gene is compact in size and is located in a chromosomal region that is replicated early in the cell cycle. CerS2 activity is regulated by sphingosine-1-phosphate (S1P) via two sphingosine-1-phosphate receptor-like residues on CerS2 that operate independently.
