The SCF complexes represent the largest family of ubiquitin-protein ligases and mediate the ubiquitination of a broad spectrum of regulatory and signalling proteins in diverse cellular pathways. The SCF consists of three invariant components, Skp1, Cul1, and Rbx1 and an interchangeable subunit, an F-box protein which is responsible for recruiting specific substrates to be ubiquitinated by the SCF. SCFBTrCP1 mediates the ubiquitination and subsequent proteasomal degradation of a variety of proteins involved in various cellular processes, these include IkBa, an inhibitor of the transcription factor NFkB and B-catenin which is involved in the Wnt signalling pathway. A number of cancers, including those in breast, colon and pancreatic tissue have been associated with the deregulation of SCFBTrCP1.
