| T1 |
0-55 |
Sentence |
denotes |
The human FA2H gene encodes a fatty acid 2-hydroxylase. |
| T2 |
56-142 |
Sentence |
denotes |
2-Hydroxysphingolipids are a subset of sphingolipids containing 2-hydroxy fatty acids. |
| T3 |
143-294 |
Sentence |
denotes |
The 2-hydroxylation occurs during de novo ceramide synthesis and is catalyzed by fatty acid 2-hydroxylase (also known as fatty acid alpha-hydroxylase). |
| T4 |
295-459 |
Sentence |
denotes |
In mammals, 2-hydroxysphingolipids are present abundantly in brain because the major myelin lipids galactosylceramides and sulfatides contain 2-hydroxy fatty acids. |
| T5 |
460-567 |
Sentence |
denotes |
Here we report identification and characterization of a human gene that encodes a fatty acid 2-hydroxylase. |
| T6 |
568-683 |
Sentence |
denotes |
Data base searches revealed a human homologue of the yeast ceramide 2-hydroxylase gene (FAH1), which we named FA2H. |
| T7 |
684-783 |
Sentence |
denotes |
The FA2H gene encodes a 372-amino acid protein with 36% identity and 46% similarity to yeast Fah1p. |
| T8 |
784-921 |
Sentence |
denotes |
The amino acid sequence indicates that FA2H protein contains an N-terminal cytochrome b5 domain and four potential transmembrane domains. |
| T9 |
922-1030 |
Sentence |
denotes |
FA2H also contains the iron-binding histidine motif conserved among membrane-bound desaturases/hydroxylases. |
| T10 |
1031-1201 |
Sentence |
denotes |
COS7 cells expressing human FA2H contained 3-20-fold higher levels of 2-hydroxyceramides (C16, C18, C24, and C24:1) and 2-hydroxy fatty acids compared with control cells. |
| T11 |
1202-1379 |
Sentence |
denotes |
Microsomal fractions prepared from transfected COS7 cells showed tetracosanoic acid 2-hydroxylase activities in an NADPH- and NADPH: cytochrome P-450 reductase-dependent manner. |
| T12 |
1380-1519 |
Sentence |
denotes |
FA2H lacking the N-terminal cytochrome b5 domain had little activity, indicating that this domain is a functional component of this enzyme. |
| T13 |
1520-1616 |
Sentence |
denotes |
Northern blot analysis showed that the FA2H gene is highly expressed in brain and colon tissues. |
| T14 |
1617-1703 |
Sentence |
denotes |
These results demonstrate that the human FA2H gene encodes a fatty acid 2-hydroxylase. |
| T15 |
1704-1801 |
Sentence |
denotes |
FA2H is likely involved in the formation of myelin 2-hydroxy galactosylceramides and -sulfatides. |
