Anti-SKP1 Antibody Picoband®

Skp1 (S-phase kinase-associated protein 1) is a small protein of approximately 160 amino acids. It is mapped to 5q31.1. 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 ly 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.

Essential component of the SCF (SKP1-CUL1-F-box protein) ubiquitin ligase complex, which mediates the ubiquitination of proteins involved in cell cycle progression, signal transduction and transcription. In the SCF complex, serves as an adapter that links the F-box protein to CUL1. The functional specificity of the SCF complex depends on the F-box protein as substrate recognition component. SCF (BTRC) and SCF (FBXW11) ubiquitination of CTNNB1 and participate in Wnt signaling. SCF (FBXW11) s ubiquitination of phosphorylated NFKBIA. SCF (BTRC) s ubiquitination of NFKBIB, NFKBIE, ATF4, SMAD3, SMAD4, CDC25A, FBXO5, CEP68 and probably NFKB2 (PubMed:25704143) . SCF (SKP2) s ubiquitination of phosphorylated CDKN1B/p27kip and is involved in regulation of G1/S transition. SCF (SKP2) s ubiquitination of ORC1, CDT1, RBL2, ELF4, CDKN1A, RAG2, FOXO1A, and probably MYC and TAL1. SCF (FBXW7) s ubiquitination of cyclin E, NOTCH1 released notch intracellular domain (NICD), and probably PSEN1. SCF (FBXW2) s ubiquitination of GCM1. SCF (FBXO32) s ubiquitination of MYOD1. SCF (FBXO7) s ubiquitination of BIRC2 and DLGAP5. SCF (FBXO33) s ubiquitination of YBX1. SCF (FBXO11) s ubiquitination of BCL6 and DTL but does not seem to ubiquitination of TP53. SCF (BTRC) mediates the ubiquitination of NFKBIA at 'Lys-21' and 'Lys-22'; the degradation frees the associated NFKB1-RELA dimer to translocate into the nucleus and to activate transcription. SCF (CCNF) s ubiquitination of CCP110. SCF (FBXL3) and SCF (FBXL21) ubiquitination of CRY1 and CRY2. SCF (FBXO9) s ubiquitination of TTI1 and TELO2. SCF (FBXO10) s ubiquitination of BCL2.
