Gene RIF (12)

26499184 Results demonstrated that upregulation of miR-34a by transfection or demethylation resulted in the enhanced apoptosis and drug sensitivity in prostate cancer cells. ATG4B, directly regulated by miR-34a through AMPK/mTOR, was involved in this process.
25652856 Purified ATG4B protein interact with LC3B in vitro.
25490467 HIV-1 Vif binds more strongly to autophagy-related protein 4 (ATG4)-cleaved form I (LC3-I) than to ATG4-cleaved form II (LC3-II) in an A3G-independent manner
24991826 ATG4B independently plays a role as a positive regulator on tumor proliferation and a negative regulator on autophagy in colorectal cancer cells.
24755409 This study identifies ATG4B as a potential biomarker for predicting therapeutic response in treatment-naive chronic myeloid leukemia stem/progenitor cells and uncovers ATG4B as a possible drug target in these cells.
23508006 The actions of ATG4 family members (particularly ATG4B) are required for the control of autophagosome fusion with late, degradative compartments in differentiating human erythroblasts.
21177865 Atg4B possessed the broadest spectrum against all substrates, followed by Atg4A for ATG8 substrates
19322194 The crystal structures of catalytically inert human Atg4B in complex with processed and unprocessed forms of LC3 showed that, on LC3 binding, the regulatory loop and the N-terminal tail of HsAtg4B undergo large conformational changes.
16704426 Murine Atg8L/Apg8L modification is mediated by human Atg4B.
16325851 crystal structure of human Atg4b by X-ray crystallography at 2.0 A resolution, and show that Atg4b is a cysteine protease whose active catalytic triad site consists of Cys74, His280 and Asp278
