Lanes 1 - 4 : Merged signal (red and green). Green - ab183039 observed at 52 kDa. Red - loading control, ab8245, observed at 37 kDa.

ab183039 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. ab183039 and ab8245 (Mouse anti-GAPDH loading control) were incubated overnight at 4°C at 1/200 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.

Supplementary information

S-phase kinase-associated protein 2 (SKP2) also known as FBL1 or p45 is an E3 ubiquitin ligase that tags proteins for degradation. It weighs around 48 kDa. SKP2 facilitates the transition from the G1 to S phase of the cell cycle by targeting cyclin-dependent kinase inhibitors for proteasomal destruction. Expressed in various tissues including key roles in proliferating cells SKP2 ensures the regulation of cell cycle progression and stability.
Biological function summary

SKP2 is part of the SCF (SKP1-CUL1-F-box) complex which is instrumental in controlling cell cycle and cell division. It regulates the degradation of p27^Kip1 and other cell cycle regulators. By modulating proteolysis SKP2 contributes to the maintenance of cell proliferation and it has essential roles in cellular responses to growth signals. Moreover SKP2 influences processes such as DNA replication through its effect on substrate interaction and ubiquitination.

Pathways

SKP2 functions inside the ubiquitin-proteasome system and impacts the PI3K/AKT signaling pathway. SKP2 advances cell cycle progression by associating with proteins like p27^Kip1 and CDK2 facilitating cell division. It modulates the phosphorylation state of numerous targets influencing signaling processes that control cell growth. This involvement aligns SKP2 with key cellular pathways that maintain cell survival and metabolic balance.

SKP2 plays an important role in cancer and cardiovascular diseases. In various cancers the aberrant expression of SKP2 connects to excessive cell proliferation and tumor growth partially through interactions with oncoproteins like Myc. In cardiovascular conditions SKP2 influences cardiac hypertrophy and might link to proteins such as cyclin-dependent kinase inhibitors. The regulation by SKP2 affects these proteins' stability impacting disease progression and potential therapeutic interventions.

Target data

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 (PubMed : 9736735, PubMed : 11931757, PubMed : 12435635, PubMed : 12769844, PubMed : 12840033, PubMed : 15342634, PubMed : 15668399, PubMed : 15949444, PubMed : 16103164, PubMed : 16262255, PubMed : 16581786, PubMed : 16951159, PubMed : 17908926, PubMed : 17962192, PubMed : 22464731, PubMed : 22770219, PubMed : 32267835). Specifically recognizes phosphorylated CDKN1B/p27kip and is involved in regulation of G1/S transition (By similarity). Degradation of CDKN1B/p27kip also requires CKS1 (By similarity). Recognizes target proteins ORC1, CDT1, RBL2, KMT2A/MLL1, CDK9, RAG2, NBN, FOXO1, UBP43, YTHDF2, and probably MYC, TOB1 and TAL1 (PubMed : 11931757, PubMed : 12435635, PubMed : 12769844, PubMed : 12840033, PubMed : 15342634, PubMed : 15668399, PubMed : 15949444, PubMed : 16103164, PubMed : 16581786, PubMed : 16951159, PubMed : 17908926, PubMed : 17962192, PubMed : 22464731, PubMed : 32267835). Degradation of TAL1 also requires STUB1 (PubMed : 17962192). Recognizes CDKN1A in association with CCNE1 or CCNE2 and CDK2 (PubMed : 9736735, PubMed : 16262255). Promotes ubiquitination and destruction of CDH1 in a CK1-dependent manner, thereby regulating cell migration (PubMed : 22770219). Following phosphorylation in response to DNA damage, mediates 'Lys-63'-linked ubiquitination of NBN, promoting ATM recruitment to DNA damage sites and DNA repair via homologous recombination (PubMed : 22464731).. Through the ubiquitin-mediated proteasomal degradation of hepatitis C virus non-structural protein 5A, has an antiviral activity towards that virus.
