Studies On E2 Conjugation Enzyme Partners Of Mulan E3 Ubiquitin Ligase, Rebekah J. Fitzpatrick

Honors Undergraduate Theses

Mulan is an E3 ubiquitin ligase embedded in the outer mitochondria membrane. Mulan’s participation in the ubiquitination process is conducted through its cytosol exposed RING finger domain, and its ability to modulate protein ubiquitination makes it a key player in mitochondrial and cellular homeostasis. Mulan is known to be involved in mitochondrial fission, fusion, mitochondrial stress, apoptosis, and Parkin-independent mitophagy. Dysregulation of Mulan in mice has been shown to correlate with human neurodegenerative disorders and heart disease. Accumulation of Mulan is predicted to be responsible for the motor neuron degeneration 2 (mnd2) phenotype in mutant mice through the deregulation of …
