Functional role of the spatial proximity of Asp114(2.50) in TMH 2 and Asn332(7.49) in TMH 7 of the mu opioid receptor.

abstract：:Autophagy is an evolutionarily conserved stress response that promotes the lysosomal degradation of intracellular components. The bone marrow stromal cell-derived growth inhibitor (BDGI) functions as a stress sensor which is upregulated by oxidative stress and DNA damage. However, the role of BDGI in autophagic respon...
