Inactivating mutations of putative phosphorylation and ubiquitination sites predicted within ORF1p sequence abolish MT1 effect on ORF1p. (A) Schematic of putative phosphorylation (ORF1 Ser) and ubiquitination (ORF1 Ub) sites predicted within the ORF1p sequence mutated to alanine. (B) Western blot analysis of ORF1p in the presence or absence of melatonin receptor 1 expression (MT1 and control, respectively). Transfection with an empty vector was used to assess background levels of ORF1p. GAPDH is used as loading control. (C) Quantitation of western blot results (N = 3). ORF1, ORF1 Ser and ORF1 Ub expression in the presence of MT1 (black bars) is normalized to their respective expression in the presence of control vector (gray bars). Error bars are standard deviation; asterisks indicate statistically significant differences between control and MT1 lanes by t-test.
