| Short Name | Romo1/Mgr2 |
| description | This entry includes a group of mitochondrial proteins, including reactive oxygen species modulator 1 (Romo1) from animals and Mgr2 from fungi. Budding yeast Mgr2 is a subunit of the TIM23 translocase complex, which translocates preproteins into and across the membrane and associates with the matrix-localized import motor. It is required for binding of Tim21 to TIM23(CORE). Mrg2 is essential for cell growth at elevated temperature and for efficient protein import []. Romo1 is responsible for increasing the level of ROS in cells. In various cancer cell lines with elevated levels of ROS there is also an increased abundance of Romo1 []. Increased Romo1 expression can have a number of other affects including: inducing premature senescence of cultured human fibroblasts [, ]and increased resistance to 5-fluorouracil []. |
