Atrogin-1/Muscle Atrophy F-box (MAFbx) is an E3 ubiquitin ligase that mediates proteolysis events that occur during muscle atrophy. This ATP-dependent ubiquitin-mediated proteolysis occurs in response to a variety of catabolic states in muscle. Atrogin is expressed in heart and skeletal muscle, and is upregulated during muscle atrophy. In addition, Atrogin expression increases in C2C12 myotubes after stimulation with cytokines. Atrogin is thought to recognize and bind to some phosphorylated proteins and promote their ubiquitination and degradation during skeletal muscle atrophy. Atrogin interacts with MyoD by ubiquitination via a sequence found in transcriptional coactivators and therefore may play an important role in the course of muscle differentiation by determining the abundance of MyoD. Mice deficient in Atrogin are resistant to muscle atrophy.

Western blot image of human recombinant Atrogin 1 (lanes 1-6). The blot was probed with rabbit polyclonal Atrogin-1 (lanes 1-3) and rat monoclonal Atrogin-1 (lanes 4-6) at 1:1000 (lanes 1 & 4), 1:2000 (lanes 2 & 5), and 1:4000 (lanes 3 & 6).

Clone M314 was generated from a synthetic peptide (coupled to carrier protein) corresponding to amino acids 23 to 35 in mouse Atrogin. This sequence is highly homologous to human and rat Atrogin (F-box only protein 32).
