β-transducin repeats-containing protein-1 (β-TrCP1) serves as the substrate recognition subunit for SCFβ-TrCP E3 ubiquitin ligases, which specifically ubiquitinate phosphorylated substrates. Three variants of β-TrCP1 are known and act as homodimer or heterodimer complexes. Here, we identified a novel full-sequenced variant, β-TrCP1-variant 4, which harbours exon II instead of exon III of variant 1, with no change in the open reading frame. The expression of β-TrCP1-variant 4 is lower than that of variant 1 or 2 in ovarian can
