CIDEC

Cell death activator CIDE-3

Interacts with CEBPB (By similarity). Interacts withCIDEA.

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.

Expressed mainly in adipose tissue, smallintestine, heart, colon and stomach and, at lower levels, in brain,kidney and liver.

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).

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).

Contains 1 CIDE-N domain.

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.
