Western Blotting

Western blot analysis of extracts from 293 cells, either untransfected or transfected with DYKDDDDK-tagged Rev-erbα expression constructs, using Phospho-Rev-erbα (Ser55/Ser59) Antibody (upper) or DYKDDDDK Tag Antibody (Binds to same epitope as Sigma's Anti-FLAG® M2 Antibody) #2368 (lower). The phospho-specificity of the antibody was verified by transfecting cells with a mutant DYKDDDDK-Rev-erbα (Ser55/59Ala) expression construct and by incubating 293/Rev-erbα (WT) extracts with (+) or without (-) λ phosphatase.
Reverse orientation c-erbA gene α (Rev-erbα, EAR-1, or NR1D1) is a widely expressed member of the orphan nuclear receptor family of proteins (1). Rev-erbα is highly expressed in adipose tissue, skeletal muscle, brain and liver, and regulates cellular proliferation and differentiation. Expression increases during differentiation in adipocytes and ectopic expression of Rev-erbα potentiates the adipocyte differentiation of 3T3-L1 cells (2). In addition, expression oscillates with circadian rhythm in liver cells and Rev-erbα regulates expression of BMAL1, ApoA-I and ApoC-III, all key regulators of circadian rhythm (3,4,5,6,7). Phosphorylation of Rev-erbα Ser55 and Ser59 by GSK3β appears to stabilize Rev-erbα protein levels and is important for synchronizing and maintaining the circadian clock (8). Rev-erbα also regulates inflammation by targeting the NF-κB responsive genes IL-6 and COX-2 (9). Rev-erbα lacks the activation function 2 domain required for ligand-dependent activation of transcription by other members of the nuclear receptor family; thus it behaves as a constitutive repressor protein, recruiting the nuclear receptor co-repressor (N-CoR)/HDAC3 complex to target genes to repress transcription (10).
