Function
Regulator of the TOR pathway, a signaling cascade that promotes cell growth in response to growth factors, energy levels, and amino acids. As part of the Ragulator complex, may activate the TOR signaling cascade in response to amino acids. May play a role in late endosomes/lysosomes biogenesis and regulate both the recycling of receptors through endosomes and the MAPK signaling pathway. May be involved in cholesterol homeostasis. May also play a role in RHOA activation (By similarity).
