FA2H Antibody - #DF12995

Catalyzes the hydroxylation of free fatty acids at the C-2 position to produce 2-hydroxy fatty acids, which are building blocks of sphingolipids and glycosphingolipids common in neural tissue and epidermis. FA2H is stereospecific for the production of (R)-2-hydroxy fatty acids. Plays an essential role in the synthesis of galactosphingolipids of the myelin sheath (By similarity). Responsible for the synthesis of sphingolipids and glycosphingolipids involved in the formation of epidermal lamellar bodies critical for skin permeability barrier. Participates in the synthesis of glycosphingolipids and a fraction of type II wax diesters in sebaceous gland, specifically regulating hair follicle homeostasis (By similarity). Involved in the synthesis of sphingolipids of plasma membrane rafts, controlling lipid raft mobility and trafficking of raft-associated proteins (By similarity).

Endoplasmic reticulum membrane>Multi-pass membrane protein. Microsome membrane>Multi-pass membrane protein.

Detected in differentiating cultured keratinocytes (at protein level). Detected in epidermis and cultured keratinocytes. Highly expressed in brain and colon. Detected at lower levels in testis, prostate, pancreas and kidney.

The histidine box domains may contain the active site and/or be involved in metal ion binding.

The N-terminal cytochrome b5 heme-binding domain is essential for catalytic activity.

Belongs to the sterol desaturase family. SCS7 subfamily.
