Protein: E3 ubiquitin-protein ligase ZNRF2 (Q8NHG8)
Organism: Homo sapiens (Human)
Function: E3 ubiquitin-protein ligase that plays a role in the establishment and maintenance of neuronal transmission and plasticity. Ubiquitinates the Na(+)/K(+) ATPase alpha-1 subunit/ATP1A1 and thereby influences its endocytosis and/or degradation. Acts also as a positive regulator of mTORC1 activation by amino acids, which functions upstream of the V-ATPase and of Rag-GTPases . In turn, phosphorylation by mTOR leads to its inhibition via targeting to the cytosol allowing a self-regulating feedback mechanism
Subcellular location: Endosome membrane; Peripheral membrane protein. Lysosome membrane; Peripheral membrane protein . Presynaptic cell membrane ; Peripheral membrane protein . Cytoplasm
