From: Keratin 18 attenuates estrogen receptor α-mediated signaling by sequestering LRP16 in cytoplasm
K18 interacts with LRP16 protein in vivo. A, MCF-7 cells were transfected with the LRP16 expression vector or empty vector. Cell lysates were immunoprecipitated (IP) and immunoblotted (IB) with the indicated antibodies. B, MCF-7 cells were transfected with Flag-tagged K18-C1 (301-430 aa) expression vector or the corresponding empty vector. Cell lysates were immunoprecipitated and immunoblotted with the indicated antibodies.
