Byers, Aiwu R. He – 12 October 2014 – βII‐Spectrin (SPTBN1) is an adapter protein for Smad3/Smad4 complex formation during transforming growth factor beta (TGF‐β) signal transduction. Forty percent of SPTBN1+/− mice spontaneously develop hepatocellular carcinoma (HCC), and most cases of human HCC have significant reductions in SPTBN1 expression.
