GFAP protein carries a distinct post-translational modification signature that facilitates its pathogenic accumulation and aggregation in astrocytes of patients who succumb to Alexander Disease very early in life.
The pseudoenzyme CPT1C is able to sense changes in intracellular malonyl-CoA levels caused by nutrients or energy stress and regulate late endosomes/lysosomes anterograde transport, necessary for proper axon growth.
Cell-based high-throughput screening identifies IBT21 as a chemical chaperone, that inhibits ER protein aggregation and prevents the cell death caused by a proteotoxin, the aggregation-prone prion protein.
Genetic lesions that compromise the ribosome P-stalk implicate direct signalling from the ribosome to the translation initiation factor eIF2 kinase GCN2 in the cellular response to amino acid starvation.

Impaired lysosomal acidification results in retention of iron inside lysosomes, triggering functional iron deficiency, dysfunctional mitochondria (especially mtDNA loss), and inflammation in vivo in a mouse model of lysosomal disease.

Through visualization of directly-labeled RhoGTPase both in vitro and in vivo, RhoGDI is found to spatiotemporally regulate RhoGTPase activity through the extraction of active RhoGTPase.
