SKP1 EMC19 OCP2 SKP1A TCEB1L S-phase kinase-associated protein 1 OCP-II Transcription elongation factor B
Molecular Weight(MW)
18658 Da
Function
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. 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(Cyclin F) directs ubiquitination of CP110
Tissue Specificity
A synthetic peptide corresponding to residues on human SKP1 was used as an immunogen.
