SACK1H and colorectal cancer: In addition to colorectal cancer cells and ameloblastoma cells, FAM83H and CK-1 were localized on keratin filaments in mouse dental ameloblasts and epidermal germinative cells in vivo and MCF10A mammary gland cells (Fig. S7), suggesting that the keratin cytoskeleton in these cells may also be regulated by FAM83H.
