To determine the impact of kindlin-3 phosphorylation in a non-hematopoietic cell, we tested the triple-negative BT549 BC cell line, which expresses high levels of kindlin-3 (Sossey-Alaoui et al, 2014) (Fig S3, BT549 lane) for reactivity with mAb 10G5. This evidence concerns the gene FERMT3 and breast cancer.
