Description générale
1-desoxymethylsphingosine is synthesized from glycine in the presence of the enzyme serine palmitoyltransferase (SPT).
Application
1-desoxymethylsphingosine may be used for the complex preparation with bovine serum albumin for cytotoxicity testing in MN9D dopaminergic neuroblastoma cell line.
Actions biochimiques/physiologiques
1-desoxymethylsphingosine is less neurotoxic compared to 1-desoxysphingosine in dorsal root ganglion neuronscultures Mutations in the palmitoyltransferase (SPT) in hereditary sensory neuropathy type 1 (HSAN-1), due to altered substrate specificity 1-desoxymethylsphinganine and 1-deoxy-sphinganine which are further converted to -deoxy(methyl)-ceramide and 1-deoxy(methyl)-sphingosine (1-deoxy(methyl)-SO). However, they lack the hydroxyl group essential for glycosphingolipid generation, resulting in accumulation of intermediate products.

HSAN1 is an inherited neuropathy found to be associated with several missense mutations in the SPTLC1 subunit of serine palmitoyltransferase (SPT). SPT catalyzes the condensation of serine and palmitoyl-CoA, the initial step in the de novo synthesis of sphingolipids. Here
