We report here that human mitochondria contain small RNA including microRNA, piRNA, tRNA, rRNA, and RNA repeats. Mitochondria from human cells were purified and RNA isolated. Small RNAs were purified, library generated and analyzed by Illumina Hiseq 2000 system. The sequencing generated 19.5 and 17....

Lactylation, a novel post-translational modification (PTM), in which a lactyl group, derived from lactate, is covalently added to lysine residues on the target proteins. Lactylation, first observed in histones in 2019, is increasingly recognized for its influence on gene expression, especially as it...

MICU1 is a Ca2+-binding protein that regulates the mitochondrial Ca2+ uniporter channel (mtCU ) and mitochondrial Ca2+ (mCa2+) uptake. MICU1 knockout mice display perinatal lethality and disorganized mitochondrial architecture. These phenotypes are distinct from other mtCU loss-of-function models an...

The mitochondrial sodium/calcium exchanger, NCLX, is critical to maintaining mitochondrial calcium homeostasis, yet little remains known about the mechanisms regulating its function. Here, we performed proximity biotinylation screening to identify the NCLX interactome and potential protein regulator...
