Rabbit Anti-CIDEC/FITC Conjugated antibody
background:
This gene encodes a member of the cell death-inducing DNA fragmentation factor-like effector family. Members of this family play important roles in apoptosis. The encoded protein promotes lipid droplet formation in adipocytes and may mediate adipocyte apoptosis. This gene is regulated by insulin and its expression is positively correlated with insulin sensitivity. Mutations in this gene may contribute to insulin resistant diabetes. A pseudogene of this gene is located on the short arm of chromosome 3. Alternatively spliced transcript variants that encode different isoforms have been observed for this gene.

Tissue specificity: Expressed mainly in small intestine, heart, colon and stomach and, at lower levels, in brain, kidney and liver.
Function:
May act as a CEBPB coactivator in white adipose tissueto control the expression of a subset of CEBPB downstream targetgenes, including SOCS1, SOCS3, TGFB1, TGFBR1, ID2 and XDH (Bysimilarity). Binds to lipid droplets and regulates theirenlargement, thereby restricting lipolysis and favoring storage. Atfocal contact sites between lipid droplets, promotes directionalnet neutral lipid transfer from the smaller to larger lipiddroplets. The transfer direction may be driven by the internalpressure difference between the contacting lipid droplet pair. Whenoverexpressed in preadipocytes, induces apoptosis or increases cellsusceptibility to apoptosis induced by serum deprivation or TGFBtreatment. As mature adipocytes, that express high CIDEC levels,are quite resistant to apoptotic stimuli, the physiologicalsignificance of its role in apoptosis is unclear.
Subunit:
Interacts with CEBPB (By similarity). Interacts withCIDEA.
Subcellular Location:
Nucleus (By similarity). Endoplasmicreticulum (By similarity). Lipid droplet. Note=Diffuses quickly onlipid droplet surface, but becomes trapped and clustered at lipiddroplet contact sites, thereby enabling its rapid enrichment atlipid droplet contact sites.
Tissue Specificity:
Expressed mainly in adipose tissue, smallintestine, heart, colon and stomach and, at lower levels, in brain,kidney and liver.
Post-translational modifications:
Ubiquitinated and targeted to proteasomal degradation,resulting in a short half-life. Protein stability depends ontriaclyglycerol synthesis, fatty acid availability and lipiddroplet formation (By similarity).
DISEASE:
Note=In omental adipose tissue of obese patients matchedfor BMI, expression levels tend to correlate with insulinsensitivity. Expression is increased 2-3 fold in the group ofpatients with high insulin sensitivity, compared to theinsulin-resistant group. This observation is consistent with theidea that triglyceride storage in adipocytes plays an importantrole in sequestering triglycerides and fatty acids away from thecirculation and peripheral tissues, thus enhancing insulinsensitivity in liver and muscle. This effect is not significant insubcutaneous adipose tissue (PubMed:18509062). In subcutaneousadipose tissue of diabetic patients, tends to negatively correlatewith body mass index and total fat mass, independently of insulinsensitivity (PubMed:18334488).
Similarity:
Contains 1 CIDE-N domain.
