Regulators of chromatin structure have emerged as a key driver of transcriptional responses inside the cell. Two such groups of regulators, histone writers and erasers; the proteins, that add or remove histone post translational modifications (PTMs), have become the central players in chromatin structure. Thus, the aberrant expression of writers and erasures is a hallmark in human diseases. For example, overexpression of the erasures histone deacetylase1 (HDAC1) and lysine specific demethylase1 (LSD1) had been reported in many cancers. Currently, HDAC inhibitors have been used successfully for cancer treatment and several inhibitors targeting LSD1 are in clinical trial. To date, apart …

Mitochondria are complex organelles that generate most of the energy required to sustain life and function in metabolic and signaling pathways required to maintain cellular homeostasis. MNRR1 (mitochondrial nuclear retrograde regulator 1 or CHCHD2) is a small, bi-organellar twin CX9C protein that is emerging as an important regulator of mitochondrial function, apoptosis, and cellular stress by participating in mitochondrial-nuclear crosstalk. Our lab has previously shown that in the mitochondria, MNRR1 regulates complex IV (Cytochrome c oxidase or COX) and is able to finetune the oxidase function through phosphorylation status. We have also shown that during stress, mitochondrial MNRR1 levels deplete, …
