  • Target

    • Function

      Substrate recognition component of a SCF (SKP1-CUL1-F-box protein) E3 ubiquitin-protein ligase complex which 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. Recognizes target proteins ORC1, CDT1, RBL2, MLL, CDK9, RAG2, FOXO1A, UBP43, and probably MYC, TOB1 and TAL1. Degradation of TAL1 also requires STUB1. Recognizes CDKN1A in association with CCNE1 or CCNE2 and CDK2.
    • Pathway

    • All lanes : Anti-SKP2 antibody [EPR3306(2)] (ab124799) at 1/1000 dilution

      Lane 1 : Wild-type HAP1 whole cell lysate
      Lane 2 : SKP2 knockout HAP1 whole cell lysate
      Lane 3 : HeLa whole cell lysate
      Lane 4 : MCF7 whole cell lysate

      Lysates/proteins at 20 µg per lane.

      Predicted band size: 46, 48 kDa

      Lanes 1 - 4: Merged signal (red and green). Green - ab124799 observed at 52 kDa. Red - loading control, ab8245, observed at 37 kDa.

      ab124799 was shown to recognize in wild-type HAP1 cells as signal was lost at the expected MW in SKP2 knockout cells. Additional cross-reactive bands were observed in the wild-type and knockout cells. Wild-type and SKP2 knockout samples were subjected to SDS-PAGE. The membrane was blocked with 3% NF Milk. Ab124799 and ab8245 (Mouse anti GAPDH loading control) were incubated overnight at 4°C at 1/1000 dilution and 1/20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.
