CC -!- FUNCTION: Catalyzes stereospecific hydroxylation of free fatty acids at
CC the C-2 position to produce (R)-2-hydroxy fatty acids, which are
CC building blocks of sphingolipids and glycosphingolipids common in
CC neural tissue and epidermis. Plays an essential role in the synthesis
CC of galactosphingolipids of the myelin sheath. Responsible for the
CC synthesis of sphingolipids and glycosphingolipids involved in the
CC formation of epidermal lamellar bodies critical for skin permeability
CC barrier. Participates in the synthesis of glycosphingolipids and a
CC fraction of type II wax diesters in sebaceous gland, specifically
CC regulating hair follicle homeostasis. Involved in the synthesis of
CC sphingolipids of plasma membrane rafts, controlling lipid raft mobility
CC and trafficking of raft-associated proteins.
