Background: SKP1/FBX07/CUL1/RBX1 Complex

SKP1 (S-phase kinase-associated protein 1) is an essential component of SCF (SKP1-CUL1-F-box protein) E3 Ubiquitin ligases that mediate the ubiquitination of proteins involved in cell cycle progression, signal transduction and transcription.  SKP1 is the adapter protein that links Cullin-1 to various F-box proteins (such as FBXO7) that serve as the substrate recognition components of SCF ligases.  FBXO7 (aka FBX7 or PARK15) plays a role in mitophagy by helping target Parkin (PARK2) to depolarized mitochondria, thereby inducing the ubiquitination of TOMM20 and other mitochondrial proteins.  Evidence from a Drosophila Parkin-/- neurodegeneration model indicates that FBXO7 can substitute for Parkin-mediated ubiquitination of mitochondrial substrates in some settings.  This recombinant protein complex consists of His-tag SKP1, FLAG-tag FBXO7, His-tag CUL1 and untagged RBX1.
