Parkin protein functions as an ubiquitin (E3) ligase that targets specific proteins for degradation in the 26S proteasome. Here, based on a mass spectrometry analysis of the human dopaminergic neuroblastoma-derived cell line SH-SY5Y that over-expresses parkin, we found that parkin may suppress cofilin phosphorylation. LIM Kinase 1 (LIMK1) is the upstream protein that phosphorylates cofilin, an actin depolymerizing protein. Thus, we postulated a possible connection between parkin and LIMK1. Our studies in other cell lines, using co-transfection assays, demonstrated that LIMK1 and parkin bind each other. LIMK1 also interacted with previously known parkin interactors Hsp70 and CHIP. Parkin enhanced LIMK1-ubiquitination in the human neuroblastoma-derived BE(2)-M17 cell line, but not in the human embryonic kidney-derived HEK293 cell line. In fact, parkin-over-expression reduced the level of LIMK1-induced phosphocofilin in the BE(2)-M17 cells but not in the HEK293 cells. Additionally, in simian kidney-derived COS-7 cells, parkin-over-expression reduced LIMK1-induced actin filament accumulation. LIMK1 in cultured cells regulates parkin reversibly: LIMK1 did not phosphorylate parkin but LIMK1 overexpression reduced parkin self-ubiquitination in vitro and in HEK293 cells. Furthermore, in the cells co-transfected with parkin and p38, LIMK1 significantly decreased p38-ubiquitination by parkin. These findings demonstrate a cell-type dependent functional interaction between parkin and LIMK1 and provide new evidence that links parkin and LIMK1 in the pathogenesis of familial PD."xsd:string |
