Designing an IHC experiment for Cysteine protease ATG4C? The guide has the expected staining pattern, antigen retrieval and fixation, antibodies backed by real IHC images, the tissue controls to run alongside, and protocols taken from published papers.
Open the ATG4C IHC GuideFacts about Cysteine protease ATG4C.
Cleaves the C-terminal amino acid of ATG8 family proteins MAP1LC3 and GABARAPL2, to show a C-terminal glycine. Exposure of the glycine at the C-terminus is vital for ATG8 proteins conjugation to phosphatidylethanolamine (PE) and insertion to membranes, which is essential for autophagy.
