Detection of Human DEC2 by Western Blot. Western blot shows lysates of human brain tissue. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human DEC2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5226) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for DEC2 at approximately 50-55 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

Background: DEC2

DEC-2 (Differentially expressed in chondrocytes protein 2; also bHLHB3, Sharp-1 and bHLHe41) is a 54-56 kDa Class B member of the bHLH superfamily of proteins. It utilizes both DNA binding and protein-protein interaction to mediate E-box transcriptional repression. Physiologically, DEC-2 is proposed to be a regulator of the sleep cycle, particularly during periods of sleep deprivation. It also interacts with HIF-1 alpha neutralizing its activation of the VEGF gene during hypoxia. Human DEC-2 is 482 amino acids (aa) in length. It contains a DNA binding motif (aa 45-57), an HLH region (aa 58-100), an Orange domain that may impart specificity to protein-protein interactions (aa 131-166) and a Gly/Ala-rich region (aa 297-431). DEC-2 forms homodimers, and heterodimers with MyoD and E-proteins. There is one potential alternate start site at Met280. Over aa 101‑287, there is less than 60% aa identity between human and mouse DEC-2.
