Western blot analysis of SKP-1/p19A and Cullin-1 was performed by loading 10ug of whole cell lysates from DMSO, MLN4924 or MG132 treated U2OS cells onto a SDS PAGE gel. Proteins were transferred, blocked and endogenous SKP-1 (right panel) and Cullin-1 (left panel) were detected using a SKP-1 mouse monoclonal antibody (Prod# 32-3800) or CUL-1 mouse monoclonal antibody (Product# 32-2400) at dilutions of 1:1000.

SKP1 / p19A Antibody (1C10F4), Prod# 32-3800 specifically detects SKP1 in human cells. The antibody may also result in weak detection of 2 unknown bands at ~37kD.
This gene encodes a component of SCF complexes, which are composed of this protein, cullin 1, a ring-box protein, and one member of the F-box family of proteins. This protein binds directly to the F-box motif found in F-box proteins. SCF complexes are involved in the regulated ubiquitination of specific protein substrates, which targets them for degradation by the proteosome. Specific F-box proteins recognize different target protein(s), and many specific SCF substrates have been identified including regulators of cell cycle progression and development. Studies have also characterized the protein as an RNA polymerase II elongation factor. Alternative splicing of this gene results in two transcript variants. A related pseudogene has been identified on chromosome 7.

F-box protein FBXL16 binds PP2A-B55α and regulates differentiation of embryonic stem cells along the FLK1+ lineage.
32-3800 was used in western blot to study the interaction between F-box protein FBXL16 and PP2A-B55alpha and its effect on the differentiation of embryonic stem cells.

Degradation of Cdc25A by beta-TrCP during S phase and in response to DNA damage.
32-3800 was used in western blot to show that beta-TrCP targets phosphorylated Cdc25A for degradation by the Skp1/Cul1/F-box protein complex.
