MGI Phenotype

FUNCTION: This gene encodes a member of the Ras-related small GTPases, which regulate membrane trafficking in organelles and transport vesicles. This protein is expressed predominantly in lipid droplets, organelles that store neutral lipids, and is proposed to play a role in lipolysis and lipogenesis. In humans mutations in this gene are associated with Warburg micro syndrome type 3. A pseudogene of this gene is located on chromosome X. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jun 2013]
PHENOTYPE: Homozygous null mice show partial perinatal lethality and abnormal eye development, and develop nuclear cataracts, atonic pupils, progressive limb weakness, disruption of neuronal cytoskeleton, and accumulation of neurofilament and microtubule proteins in synaptic terminals.
