atg4b被认为是atg4的主要异构体,因为它对所有底物具有最宽的谱,其次是atg4a,而atg4c和atg4d的活性最低。 LC3-I最终与PE分子结合形成膜结合型LC3-II。 LC3-II特异性地针对伸长的自噬体,在与溶酶体融合之前一直停留在自噬小体上。
Autophagy-regulating protease Atg4: structure, function, …
2017年9月13日 · Autophagy is mediated by dozens of autophagy-related (Atg) proteins, among which Atg4 is the sole protease that regulates autophagy through the processing and deconjugating of Atg8. As the Atg4...
ATG4B - Wikipedia
Cysteine protease ATG4B is an enzyme that in humans is encoded by the ATG4B gene. [4] Autophagy is the process by which endogenous proteins and damaged organelles are destroyed intracellularly. Autophagy is postulated to be essential for cell homeostasis and cell remodeling during differentiation, metamorphosis, non-apoptotic cell death, and aging.

本研究揭示了ATG4家族蛋白的ATG4B,在维持固有免疫平衡中的调控作用。 在病毒感染后,ATG4B能够招募TBK1靶向自噬蛋白GABARAP,TBK1通过其LIR (Lc3--interacting region)motif与GABARAP的LDS (LIR docking site)结合,使得TBKI被GABARAP包裹进自噬小体,并输送至自噬溶酶体中降解。 此外,ATG4B的特异性小分子抑制剂S130,能够通过抑制ATG4B的活性解除ATG4B介导的TBK降解,从而增强TBK1,增强 抗病毒免疫反应,抑制病 …
ATG4B重组蛋白:自噬调控的精密剪刀—艾普蒂生物 - 哔哩哔哩
2023年11月22日 · ATG4B(Autophagy-related 4B)重组蛋白是自噬调控中的一员,扮演着精密剪切和激活ATG8家族蛋白的角色。 本文将深入研究ATG4B重组蛋白的结构特征、功能,以及其在自噬过程和细胞生物学中的关键作用。
自噬相关的 4B 半胱氨酸肽酶(ATG4B)基因 | MCE
Autophagy is postulated to be essential for cell homeostasis and cell remodeling during differentiation, metamorphosis, non-apoptotic cell death, and aging. Reduced levels of Autophagy have been described in some malignant tumors, and a role for Autophagy in controlling the unregulated cell growth linked to Cancer has been proposed.
MST4 Phosphorylation of ATG4B Regulates Autophagic Activity
2017年12月11日 · Inhibiting ATG4B in combination with radiotherapy in treating mice with intracranial GBM xenograft markedly slows tumor growth and provides a significant survival benefit. Our work describes an MST4-ATG4B signaling axis that influences GBM autophagy and malignancy, and whose therapeutic targeting enhances the anti-tumor effects of radiotherapy.
