Fig. 3: MOP phosphorylation pattern in vivo.
From: HA-MOP knockin mice express the canonical µ-opioid receptor but lack detectable splice variants

HA-MOP mice were either treated with different MOP agonists, naltrexone, or saline. Western blots of brain lysates immunoblotted with anti-pThr370 (first panel), anti-pS375 (second panel), anti-pThr376 (third panel), or anti-pThr379 (fourth panel) antibodies. Blots were stripped and reprobed with a UMB-3 antibody to control for equal loading. Positions of molecular mass markers are indicated on the left (in kDa). Blots are representative of four independent experiments.
