Reference: Lim MK et al.(2007) Parkin interacts with LIM Kinase 1 and reduces its cofilin-phosphorylation activity via ubiquitination Exp. Cell Res. 313: 2858-2874 [PMID: 17512523]

Interaction Information:

Comment Parkin interacts with LIMK1 also in the presence of CHIP. Surprisingly, the presence of increasing CHIP potentiated LIMK1 association with parkin in a dose-dependent manner.
Formal Description
Interaction-ID: 4397

LIMK1

also in the presence of CHIP
Comment Parkin interacts with LIMK1 and LIMK2.

LIMK2

Comment Parkin also interacts with the F-box/WD repeats domain protein, hSel-10. Sel10 did not alter the interaction between parkin and LIMK1.

FBXW7

Comment Immunoprecipitation of FLAG-Hsp70 resulted in Co-IP of HA-parkin and HA-LIMK1.

HSP70

interacts (colocalizes) with

gene/protein

PRKN

Comment Parkin enhanced ubiquitination of LIMK1 in vitro and only in neuroblastoma-derived BE(2)-M17 cells, but not in embryonic kidney-derived HEK293 cells. Instead, parkin reduced LIMK1-ubiquitination in HEK293 cells.
