Function
Component of a lipid metabolic pathway that catalyzes biosynthesis of highly unsaturated fatty acids (HUFA) from precursor essential polyunsaturated fatty acids (PUFA) linoleic acid (LA) (18:2n-6) and alpha-linolenic acid (ALA) (18:3n-3). Catalyzes the first and rate limiting step in this pathway which is the desaturation of LA (18:2n-6) and ALA (18:3n-3) into gamma-linoleic acid (GLA) (18:3n-6) and stearidonic acid (18:4n-3) respectively and other desaturation steps. Highly unsaturated fatty acids (HUFA) play pivotal roles in many biological functions. It catalizes as well the introduction of a cis double bond in palmitate to produce the mono-unsaturated fatty acid sapienate, the most abundant fatty acid in sebum. -
Tissue specificity
Expressed in a wide array of tissues, highest expression is found in liver followed by brain, lung, heart, and retina. A lower level is found in breast tumor when compared with normal tissues; lowest levels were found in patients with poor prognostic index. -
Pathway
Lipid metabolism; polyunsaturated fatty acid biosynthesis. -
Sequence similarities
Belongs to the fatty acid desaturase family.
Contains 1 cytochrome b5 heme-binding domain. -
Developmental stage
Found in fetal heart. -
Domain
The histidine box domains may contain the active site and/or be involved in metal ion binding. -
Cellular localization
Endoplasmic reticulum membrane. - Information by UniProt

FADS2 was immunoprecipitated using 0.5mg HepG2 whole cell extract, 5µg of Rabbit polyclonal to FADS2 and 50µl of protein G magnetic beads (+). No antibody was added to the control (-).
The antibody was incubated under agitation with Protein G beads for 10min, HepG2 whole cell extract lysate diluted in RIPA buffer was added to each sample and incubated for a further 10min under agitation.
Proteins were eluted by addition of 40µl SDS loading buffer and incubated for 10min at 70oC; 10µl of each sample was separated on a SDS PAGE gel, transferred to a nitrocellulose membrane, blocked with 5% BSA and probed with ab72189.

Developed using the ECL technique.
Performed under reducing conditions.
Predicted band size: 52 kDa
Observed band size: 45 kDa why is the actual band size different from the predicted?
Additional bands at: 62.5 kDa. We are unsure as to the identity of these extra bands.
Exposure time: 2 minutes
ab72189 detects a strong band at 45 kDa in human liver and brain tissue lysates, aswell as hela and hepG2 whole cell lysates. This antibody was raised against an immunogen that is predicted to cross react with all known isoforms of Fatty acid desaturase 2 (FADS2). FADS2 has three isoforms, isoform one has a molecular weight of 52 kDa with isoforms two and three a molecular weight of 49 and 45 respectively(SwissProt data). The band we have observed is thought to represent isoform 3 of FADS2 (45 kDa).
