NMR resonance assignment of the N-terminal GTPase domain of human Miro2 Bound to GTP.

ABSTRACT: Miro2 and Miro1 are mitochondrial-associated proteins critical for regulating mitochondrial movement within the cell. Both Miro1 and Miro2 have roles in promoting neuron function, but recently Miro2 has been shown to have additional roles in response to nutrient starvation in tumor cells. Miro1 and 2 consist of two small GTPase domains flanking a pair of EF-hands. The N-terminal GTPase (nGTPase) domain is responsible for initiating mitochondrial trafficking and interactions with GCN1 in prostate cancer. The crystal structure of Miro1 nGTPase bound to GTP has been solved. However, no structural data is available for the nGTPase domain of Miro2. To better understand the similarities and differences in the functions of Miro1 and Miro2, we have initiated structural studies of Miro2. Here we re
