    Summary
    Enables GTPase activator activity. Involved in several processes, including cellular response to nitrogen starvation; negative regulation of intracellular signal transduction; and regulation of autophagosome assembly. Acts upstream of or within cellular response to oxidative stress. Located in fungal-type vacuole membrane. Part of GATOR1 complex. Used to study cancer. Human ortholog(s) of this gene implicated in developmental and epileptic encephalopathy and familial focal epilepsy with variable foci 1. Orthologous to human DEPDC5 (DEP domain containing 5, GATOR1 subcomplex subunit). [provided by Alliance of Genome Resources, Dec 2024]

    What's a GeneRIF?
    1. Upon amino acid deprivation, Iml1 transiently interacts with Gtr1 at the vacuolar membrane stimulating its intrinsic GTPase activity, thus decreasing the activity of TORC1.

    2. Iml1p contains a conserved domain that is required for non-nitrogen starvation-induced autophagy as well as complex formation

    • GTPase-activating protein (GAP) subunit of the Iml1p/SEACIT complex; SEACIT (Iml1p-Npr2p-Npr3p) is required for non-nitrogen-starvation (NNS)-induced autophagy, and is a subcomplex of the SEA, a coatomer-related complex that associates with the vacuole; Iml1p functions as a GAP for the Rag family GTPase Gtr1p (EGOC subunit) in SEACIT, resulting in the inhibition of TORC1 signaling in response to amino acid deprivation; role in the oxidative stress response
