Protein Domain : Sphingolipid delta4-desaturase, N-terminal IPR013866

Type	Domain
Description	This small domain appears to be specific to sphingolipid delta 4-desaturase. Sphingolipids are important membrane signalling molecules involved in many different cellular functions in eukaryotes. Sphingolipid delta 4-desaturase catalyses the formation of (E)-sphing-4-enine [ ]. Some proteins with this domain have bifunctional delta 4-desaturase/C-4-hydroxylase activity. Delta 4-desaturated sphingolipids may play a role in early signalling required for entry into meiotic and spermatid differentiation pathways during Drosophila spermatogenesis [].
