Adapter protein implicated in the regulation of a large spectrum of both general and specialized signaling pathways ( ). Binds to a large number of partners, usually by recognition of a phosphoserine or phosphothreonine motif ( ). Binding generally results in the modulation of the activity of the binding partner . Promotes inactivation of WDR24 component of the GATOR2 complex by binding to phosphorylated WDR24 .
Subcellular locations: Cytoplasm
Highly expressed in brain, skeletal muscle, and heart.
