BTRC (gene)

F-box/WD repeat-containing protein 1A (FBXW1A) also known as βTrCP1 or Fbxw1 or hsSlimb or pIkappaBalpha-E3 receptor subunit is a protein that in humans is encoded by the BTRC (beta-transducin repeat containing) gene.

This gene encodes a member of the F-box protein family which is characterized by an approximately 40 residue structural motif, the F-box. The F-box proteins constitute one of the four subunits of ubiquitin protein ligase complex called SCFs ( Skp1-Cul1-F-box protein), which often, but not always, recognize substrates in a phosphorylation-dependent manner. F-box proteins are divided into 3 classes:

  • Fbxws containing WD40 repeats,
  • Fbxls containing leucine-rich repeats,
  • and Fbxos containing either "other" protein–protein interaction modules or no recognizable motifs.

The protein encoded by this gene belongs to the Fbxw class as, in addition to an F-box, this protein contains multiple WD40 repeats. This protein is homologous to Xenopus βTrCP, yeast Met30, Neurospora Scon2 and Drosophila Slimb. In mammals, in addition to βTrCP1, a paralog protein (called βTrCP2 or FBXW11) also exists, but, so far, their functions appear redundant and indistinguishable.
