For FAM83G, we got the typical immunohistochemical positive pictures of FAM83G in breast cancer patients’ specimens, its subcellular location (mainly enriched in cytosol), the FAM83G mRNA level of different cell lines ordered by organ of phenotypic resemblance, immunofluorescence staining result of FAM83G in U-251 MG cells. This evidence concerns the gene SACK1G and breast carcinoma.
