In breast cancer, the antiestrogen tamoxifen has been prescribed for both primary treatment and the treatment of advanced metastatic disease. Although the drug induces remission in most patients with estrogen receptor-positive disease, all patients eventually develop resistance. van Agthoven et al. (1998) applied an insertional mutagenesis strategy to a breast cancer cell line. Infected cells were subjected to tamoxifen selection, and the resistant clones were screened for a common integration site linked with antiestrogen resistance. By screening a human testis cDNA library with the integration site-specific probe, they obtained a cDNA encoding BCAR3 (breast cancer antiestrogen resistance 3). The deduced 825aa BCAR3 protein contains a putative Src homology 2 (SH2) domain and sequences homologous to yeast CDC48. Northern blot analysis detected abundant expression of a 3.4kb BCAR3 transcript in heart, placenta, skeletal muscle, spleen, prostate, testis, ovary, small intestine, colon, fetal kidney, and several cancer cell lines, but not in nonmalignant breast tissue; a 6kb BCAR3 transcript was also detected in skeletal muscle and heart.
