Miro GTPases are a separate family of Ras-related GTPases that are sometimes included in the atypical RHO GTPases group, but are phylogenetically distinct from the Rho family (Jaffe and Hall 2005; Boureux et al. 2007; Devine et al. 2016; Liu et al. 2017). Miro GTPases possess an additional GTPase domain more closely related to Rheb (Klosowiak et al. 2013). Miro family of RAS-like GTPases includes two members, RHOT1 and RHOT2. RHOT1 and RHOT2 regulate the movement of mitochondria (Schwarz 2013; Devine et al. 2016) and peroxisomes (Castro et al. 2018, Okumoto et al. 2018, Covill-Cooke et al. 2020).
