Preparation and Storage

Background: beta-TrCP1/BTRC

beta -TrCP1, also called BTRC ( beta -transducin repeat containing E3 ubiquitin ligase), FBW1A (F-box/WD repeat containing 1A) and FBXW1A, is an approximately 63-70 kDa protein that associates with Skp1, Cullin, and RBX1 to form an SCF ubiquitin ligase complex. These complexes regulate the degradation of a wide variety of proteins including transcription factors, signal transduction molecules, and cytokine receptors. They play important roles in regulation of the inflammatory response, cell cycle, apoptosis, tumorigenesis, and the response to DNA damage. beta -TrCP1 can form homodimers and heterodimers with beta -TrCP2, which associate into SCF complexes with distinct substrate preferences. Human beta -TrCP1 contains a dimerization domain (aa 128-177), an F-box domain (aa 181-228), and seven tandem WD repeats (aa 301‑590). The WD repeats assemble into a beta propeller structure that binds to phosphorylated destruction motifs in the substrate. Alternate splicing generates a short isoform with a 36 aa deletion near the N-terminus. Within aa 1-120 of the 63 kDa short isoform, human beta -TrCP1 shares 98% and 91% aa sequence identity with mouse and rat beta -TrCP1, respectively.
