ab172730 - Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody.
FunctionCysteine protease required for autophagy, which cleaves the C-terminal part of either MAP1LC3, GABARAPL2 or GABARAP, allowing the liberation of form I. A subpopulation of form I is subsequently converted to a smaller form (form II). Form II, with a revealed C-terminal glycine, is considered to be the phosphatidylethanolamine (PE)-conjugated form, and has the capacity for the binding to autophagosomes.
Tissue specificityMainly expressed in the skeletal muscle, followed by brain, heart, liver and pancreas.
Sequence similaritiesBelongs to the peptidase C54 family.

Lane 1: Wild-type HAP1 cell lysate (20 µg)
Lane 2: ATG4B knockout HAP1 cell lysate (20 µg)
Lanes 1 - 2: Merged signal (red and green). Green - ab154843 observed at 47 kDa. Red - loading control, ab18058, observed at 130 kDa.
ab154843 was shown to specifically react with ATG4B when ATG4B knockout samples were used. Wild-type and ATG4B knockout samples were subjected to SDS-PAGE. ab154843 and ab18058 (loading control to Vinculin) were diluted at 1/1000 and 1/10000 respectively and incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.
