Researchers provide critical insights into the molecular mechanisms underlying lysophagy

Autophagy is a self-degradation process that cells use to remove unneeded or damaged components. There are several forms of autophagy, including macroautophagy, which is a bulk degradation system used to target materials in the cell's cytosol to organelles called lysosomes for enzymatic breakdown.

Unraveling how strigoractone hormone regulates massive gene networks controlling plant growth

As sessile organisms, plants have to continually adapt their growth and architecture to the ever-changing environment. To do so, plants have evolved distinct molecular mechanisms to sense and respond to the environment and integrate the signals from outside with endogenous developmental programs.

New analysis method to identify interacting proteins in a protein degrader-dependent manner

Protein degraders, which induce the protein degradation of target proteins, are expected to be the "next-generation drugs" because they can remove disease-related proteins from cells.

Research shows how loss of de-N-glycosylation enzyme causes detrimental effects

Peptide: N-glycanase (NGLY1) is an evolutionarily conserved enzyme for removing N-linked glycans (N-glycans) from glycoproteins and is involved in proteostasis of N-glycoproteins in the cytosol. In 2012, a rare genetic disorder called NGLY1 deficiency was discovered by an exome analysis.
