Figure Lengend Snippet: PGAM5 interferes with PINK1 processing independently of its phosphatase activity. A. PGAM5 mutant and isoform lacking phosphatase activity induce Parkin translocation. PC6 cells were transfected with Parkin-EYFP and PGAM5 wt, PGAM5 F244D or short PGAM5 isoform (isoform 2, UniProt #Q96HS1-2). ****P < 0.0001, n = 6 dishes, 20 fields per dish, Welch's ANOVA followed by Dunnett's T3 multiple comparisons test. B. PGAM5 mutant lacking PARL/OMA1 cleaving site does not induce Parkin translocation. PC6 cells were transfected with Parkin-EYFP and PGAM5 or PGAM5 S24F. ****P < 0.0001, n = 6 dishes, 20 fields per dish, Welch's ANOVA followed by Dunnett's T3 multiple comparisons test. C. TOMM7 overexpression increases the fraction of full-length PGAM5 in HEK293 cells expressing PGAM5-flag and TOMM7-myc. D. TOMM7 overexpression protects partially against PGAM5 induced Parkin translocation. PC6 cells were transfected with Parkin-EYFP, PGAM5 wt or/and TOMM7. ****P < 0.0001, n = 9 dishes, 20 fields per dish, Welch's ANOVA followed by Dunnett's T3 multiple comparisons test. E. OMA1 and PARL protect partially against PGAM5 induced Parkin translocation. PC6 cells were transfected with Parkin-EYFP, PGAM5 wt and PARL or OMA1. ****P < 0.0001, n = 6 dishes, 20 fields per dish, One-way ANOVA followed by Sidak's multiple comparisons test.
