In this study, 10 PpGRF genes distributed on 6 chromosomes were identified in peach genome and their properties were analyzed systematically. Expression pattern analysis suggested that most PpGRFs were preferentially expressed in young tissues. Multiple types of...

KAT7-mediated CANX (calnexin) crotonylation regulates leucine-stimulated MTORC1 activity

Guokai Yan, Xiuzhi Li, Zilong Zheng, Weihua Gao, Changqing Chen, Xinkai Wang, Zhongyi Cheng, Jie Yu, Geng Zou, Muhammad Zahid Farooq, Xiaoyan Zhu, Weiyun Zhu, Qing Zhong & Xianghua Yan
Amino acids play crucial roles in the MTOR (mechanistic target of rapamycin kinase) complex 1 (MTORC1) pathway. However, the underlying mechanisms are not fully understood. Here, we establish a cell-free system to mimic the activation of MTORC1, by which we identify CANX (calnexin) as an essential regulator for leucine-stimulated MTORC1 pathway. CANX translocates to lysosomes after leucine deprivation, and its loss of function renders either the MTORC1 activity or the lysosomal translocation of MTOR insensitive...

Phosphatidic acid suppresses autophagy through competitive inhibition by binding GAPC (glyceraldehyde-3-phosphate dehydrogenase) and PGK (phosphoglycerate kinase) proteins

Bin Guan, Yu-Tong Jiang, De-Li Lin, Wen-Hui Lin & Hong-Wei Xue
Macroautophagy/autophagy is a finely-regulated process in which cytoplasm encapsulated within transient organelles termed autophagosomes is delivered to lysosomes or vacuoles for degradation. Phospholipids, particularly phosphatidic acid (PA) that functions as a second messenger, play crucial and differential roles in autophagosome formation; however, the underlying mechanism remains largely unknown. Here we demonstrated that PA inhibits autophagy through competitive inhibition of the formation of ATG3 (autophagy-related)-ATG8e and ATG6-VPS34 (vacuolar protein sorting 34) complexes. PA bound to GAPC...
