    text ULK1 and the GABARAP proteins co-localized to many kind of neurons such as pyramidal cells of the hippocampus, mitral cells of the olfactory bulb, and Purkinje cells of the cerebellum
    basic FUNCTION
  • involved in axon growth and required for granule cell axon formation, via Ras-like GTPase signaling and through regulation of the RAB5-mediated endocytic pathways within developing axons
  • autophagy factor that functions together with ULK2 and RBCC1
  • playing an essential role in neurite extension of cerebellar granule cells
  • serine threonine kinase, which is a critical regulator of mitochondrial and ribosomal clearance during the final stages of erythroid maturation
  • play critical roles during the activation of autophagy
  • phosphorylates AMBRA1, releasing the autophagy core complex from dynein
  • having a cytoprotective function in neurons, and being an essential component of the autophagic signaling pathway
  • ULK1 and ULK2 are transcriptional targets of tumor suppressor TP53, and in response to DNA damage, are upregulated by TP53
  • ULK1 and ULK2 may mediate part of tumor suppression activity in mammalian cells and contribute to the efficacy of genotoxic chemotherapeutic drugs
  • ULK1/2 are required in the autophagy response to amino acid deprivation but not for autophagy induced by deprivation of glucose or inhibition of glucose metabolism
  • ULK1 and ULK2, are multifunctional proteins with roles in autophagy, neurite outgrowth, and vesicle transport
  • critical autophagy protein near the apex of the hierarchal regulatory pathway that receives signals from the master nutrient sensors MTOR and AMP-activated protein kinase (AMPK)
  • ULK1 and ULK2 both function to support autophagy activation following nutrient starvation
  • negatively regulates IFNB production by phosphorylating TMEM173 S366
  • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling
    a component
  • component of the selective autophagy machinery that leads to the elimination of organelles in erythroid cells rather that an essential mechanistic component of autophagy
  • ULK1 forms a complex with AMPK, and AMPK activation results in ULK1 phosphorylation (ULK1-AMPK signaling cassette is involved in regulation of the autophagy machinery)
  • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • interacts with GABARAP (important to vesicle transport and axonal elongation in mammalian neurons) and GABARAPl2
  • PRKAA1, PRKAG1, PRKAB1 association with ULK1 plays an important role in autophagy induction, at least in part, by phosphorylation of raptor to lift the inhibitory effect of MTOR on the ULK1 autophagic complex
  • induces multisite phosphorylation of RAPTOR, and potentially contributes to MTOR inhibition through hindrance of substrate docking to RAPTOR
  • TAB2 also interacts with ATG13 and is phosphorylated by ULK1
  • ATG13 function is strictly depends on RB1CC1 binding, and has an additional function independent of ULK1/2 (
