Intrinsically disordered protein which may negatively regulate mTOR signaling pathway by stabilizing the mTOR complex component DEPTOR. Negatively regulates angiogenesis. Negatively regulates cell growth (By similarity). May play a role in neuronal development (PubMed:30080879). At 5 dpf, expressed in larvae brain and spinal cord. Mutant animals show no gross developmental abnormalities. They have enhanced fear-evoked freezing and compromised C-start responses. Mutant brains exhibit up-regulation of mTOR signaling. Belongs to the MINAR family. MINAR1 topology is a matter of debate, some authors think the N-terminus is extracellular, while preliminary experimental results suggest a cytosolic location.
