HOST SPECIES:Rabbit
SPECIES REACTIVITY: Human, Mouse, Rat
IMMUNOGEN: ATG4C antibody was raised against an 18 amino acid peptide near the carboxy terminus of human ATG4C.

The immunogen is located within the last 50 amino acids of ATG4C.
TESTED APPLICATIONS: ELISA, IF, IHC-P, WB
APPLICATIONS: ATG4C antibody can be used for detection of ATG4C by Western blot at 1 - 2 μg/ml. Antibody can also be used for Immunohistochemistry starting at 5 μg/mL. For immunofluorescence start at 20 μg/mL.

Antibody validated: Western Blot in human samples; Immunohistochemistry in human samples and Immunofluorescence in human samples. All other applications and species not yet tested.
SPECIFICITY: ATG4C antibody is human, mouse and rat reactive. ATG4C is predicted to not cross-react with other ATG4 proteins.

psi-iconBackground and References
BACKGROUND:Autophagy, the process of bulk degradation of cellular proteins through an autophagosomic-lysosomal pathway is important for normal growth control and may be defective in tumor cells. It is involved in the preservation of cellular nutrients under starvation conditions as well as the normal turnover of cytosolic components (1,2). ATG4C, also known as autophagin-3, is one of four mammalian orthologs of the yeast ATG4 protein; all four are cysteine proteases (3). Recent studies have shown that ATG4C and Beclin-1 are regulated by the microRNA miR-376b; overexpression of miR-376b led to decreased mRNA and protein levels, thereby blocking starvation and TOR inhibition-related autophagy (4).
