Specificity

Rabbit anti-ATG5 (N-terminal) recognizes human, rat, and mouse Atg5-Atg12 complex.

Immunogen

synthetic peptide corresponding to amino acids 2-15 of human ATG5, conjugated to KLH via a C-terminal cysteine residue. The corresponding sequence is identical in rat and mouse.

Application

Anti-ATG5 (N-terminal) antibody has been used:
  • in immunoblotting
  • in immunofluorescence
  • in western blotting

Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below.
Western Blotting (1 paper)
Rabbit anti-ATG5 (N-terminal specific) was used for western blot analysis to detect the level of ATG5 in SK-N-MC cells after transduction with an adenovirus expressing a shRNA specific to ATG5.
Rabbit anti-ATG5 has been used for immunofluorescence and chemiluminescent western blot analyses.

Biochem/physiol Actions

Atg5 (Apg5) is a 32 kDa protein that is required for autophagy. Atg5 is covalently modified by Atg12, a ubiquitin-like modifier. The Atg12-Atg5-Atg16 complex thus formed, localizes to autophagosome precursors and regulates autophagosome formation. Studies have reported that Atg5 fragment that is formed by calpain cleavage has pro-apoptotic properties.

Physical form

Initially described as a nonspecific degradation process induced upon starvation, autophagy is now known also to be involved in the degradation of specific ubiquitinated substrates such as mitochondria, bacteria and aggregated proteins, ensuring crucial functions in cell physiology and immunity.
Denitsa S Petkova et al.
Viruses, 9(5) (2017-05-23)
Autophagy is a potent cell autonomous defense mechanism that engages the lysosomal pathway to fight intracellular pathogens. Several autophagy receptors can recognize invading pathogens in order to target them towards autophagy for their degradation after the fusion of pathogen-containing autophagosomes
Defective autophagy in vascular smooth muscle cells accelerates senescence and promotes neointima formation and atherogenesis

Autophagy-related gene (Atg) 5 is a gene product required for the formation of autophagosomes. Here, we report that Atg5, in addition to the promotion of autophagy, enhances susceptibility towards apoptotic stimuli. Enforced expression of Atg5-sensitized tumour cells to anticancer drug
