Whereas the antibody detected the four reported or predicted FAM57A variants upon ectopic overexpression, all investigated cervical cancer cell lines only detectably expressed the FAM57A isoform 1 (FAM57A-1 or CT120A) (Figure S3a,b), as corroborated by isoform-specific RNAi (RNA interference) analysis (Figure S3c,d). Here, TLCD3A is linked to cervical carcinoma.
