FAD4L2 is a gene associated with fatty acid desaturation and oil biosynthesis. In studies on oilseed crops (e.g., sesame), FAD4L2 exhibits elevated expression during early seed development stages (10 and 20 days post-anthesis, DPA), alongside other lipid-related genes like WSD1/DGAT and LPAAT . This suggests its role in regulating unsaturated fatty acid composition during seed maturation.
| Gene | Expression Peak (DPA) | Function | Source |
|---|---|---|---|
| FAD4L2 | 10–20 DPA | Fatty acid desaturation | |
| WSD1/DGAT | 10–20 DPA | Diacylglycerol acyltransferase | |
| LPAAT | 10–20 DPA | Lysophosphatidic acid acyltransferase |
For proteins like FAD4L2, antibody generation typically follows standardized protocols:
Immunogen Selection: Recombinant FAD4L2 protein or synthetic peptides representing conserved regions.
Hybridoma Technology: Fusion of immunized mouse spleen cells with myeloma cells (e.g., P3x63Ag8U1) .
Screening: ELISA, Western blot, and immunohistochemistry to validate specificity .
Antibody efficacy depends on rigorous validation:
ELISA vs. Functional Assays: ELISA positives may fail in immunohistochemistry or Western blotting due to epitope conformational changes .
Isoform Specificity: FAD4L2 antibodies must distinguish between paralogs (e.g., FAD4) to avoid off-target effects .
While no FAD4L2-specific antibodies are documented, emerging strategies include:
FAD4L2 is a fatty acid desaturase enzyme responsible for producing specific molecular species of chloroplast phosphatidylglycerol. Its function is to catalyze the introduction of a trans double bond near the carboxyl group of palmitic acid, specifically within the phosphatidylglycerol molecule esterified at the sn-2 glyceryl carbon position.
