Atrogin 1 Recombinant Protein


Application / Dilution
WB10 μl/lane

Size 100 μl



Muscle proteolysis is regulated by the ATP-dependent ubiquitin–proteasome system. This system involves ubiquitination of specific proteins, leading to recognition and degradation by the 26S proteasome complex. Ubiquitination requires interactions with ubiquitin related proteins, ubiquitin-activating (E1), ubiquitin-conjugating (E2) and ubiquitin-ligating enzymes (E3) known as ligases. Two muscle specific ubiquitin ligases have been identified, muscle ring finger 1 (MuRF-1) and Atrogin 1. Both ligases are regulated by the Akt1/FOXO1 signaling pathway, and both proteins have been shown to be upregulated prior to the onset of atrophy in multiple models of muscle wasting, including disuse and cachexia.

Human recombinant Atrogin 1 is a 54 kDa protein that includes the full length sequence along with N-terminal His tag and Sumo fusion tag. This Atrogin 1 fusion protein is detected by rabbit polyclonal anti-Atrogin 1 and rat monoclonal anti-Atrogin 1.

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).

Atrogin 1 recombinant protein lysate is supplied at a concentration of 0.5 μg/µl in electrophoresis sample buffer (62.5 mM Tris pH 6.8, 2% SDS, 5% glycerol, 0.003% bromophenol blue, 0.9% β-mercaptoethanol). Store at –20°C. Do not boil or dilute. Stable for 1 year.
