Predicted to enable protein kinase activity. Predicted to contribute to GTPase activator activity. Predicted to be involved in several processes, including cellular response to starvation; negative regulation of TOR signaling; and regulation of autophagosome assembly. Predicted to be located in lysosomal membrane. Predicted to be part of GATOR1 complex. Human ortholog(s) of this gene implicated in focal epilepsy. Orthologous to human NPRL2 (NPR2 like, GATOR1 complex subunit). [provided by Alliance of Genome Resources, Apr 2022]
