Phospho-ATG4B (Ser383) Recombinant antibody

• 

  WB analysis using 85703-1-RR

  Jurkat cell lysates were subjected to SDS PAGE followed by western blot with 85703-1-RR (Phospho-ATG4B (Ser383) antibody) blocked with BSA only, Phospho-ATG4B (Ser383) peptide or non-Phospho peptide at dilution of 1:1000 incubated at room temperature for 1.5 hours. The membrane was stripped and re-blotted with GAPDH (60004-1-Ig) antibody as a loading control.

Background Information

ATG4B stimulates autophagy by promoting autophagosome formation through reversible modification of ATG8. In humans, microtubule-associated protein 1 light chain, LC3B, is the best-characterized ATG8 isoform, and ATG4B, but not three other ATG4 isoforms, displays a highly selective preference toward LC3B. MST4 phosphorylates ATG4B at serine residue 383, which stimulates ATG4B activity and increases autophagic flux. (PMID: 29232556, PMID: 36056541)
