Predicted to enable identical protein binding activity and kinase activator activity. Predicted to be involved in phosphatidylinositol biosynthetic process and positive regulation of kinase activity. Predicted to act upstream of or within response to osmotic stress. Predicted to be located in cytosol and vacuolar membrane. Predicted to be part of PAS complex. Predicted to be active in endosome membrane. Predicted to be extrinsic component of vacuolar membrane. Is expressed in embryo and extraembryonic component. Human ortholog(s) of this gene implicated in striatonigral degeneration. Orthologous to human VAC14 (VAC14 component of PIKFYVE complex). [provided by Alliance of Genome Resources, Apr 2022]
