SKP2 (human)

Overview
SKP2 an F-box protein of the SCF (SKP1-CUL1-F- box protein) E3 ubiquitin ligase system. The F-box component of the SCF complex is responsible for recognizing different substrates for ubiquitination. The SCF E3 complex mediates the ubiquitination and subsequent proteasomal degradation of target proteins involved in cell cycle progression, signal transduction and transcription. Specifically recognizes phosphorylated CDKN1B/p27kip and is involved in regulation of G1/S transition. Degradation of CDKN1B/p27kip also requires CKS1. Three alternatively-spliced isoforms have been described. Note: This description may include information from UniProtKB.
