Fig 3. PARK2 interacts with FBXW8 and is recruited into insolubility in Atxn2-CAG42-KIN mice.

Fig 3

(A) In HeLa cells overexpressing Cherry-GFP-PARK2 and FBXW8-HA, pulling with anti-FBXW8 antibody resulted in the detection of FBXW8 as well as of PARK2 in Co-IP lysates, demonstrating their interaction (experiment repeated twice, representative image). (B) PARK2 interacts with FBXW8 in Co-IP samples of Atxn2-CAG42-KIN mice independent of the polyQ length. Lower bands represent PARK2 protein (experiment repeated once). (C) PARK2 protein level is decreased in the RIPA-soluble fraction while it is increased in the SDS-soluble fraction (8 Atxn2 CAG1/CAG1 mice vs. ≥ 6 Atxn2 CAG42/CAG42 mice).
