Overexpression of Bbs4-HA and Bbs6-cmyc constructs Phalloidin-rhodamine staining (yellow) and overexpression of Bbs4-HA and Bbs6-myc tagged (white) (A) Overexpression of Bbs4-HA or Bbs6-myc resulted in deficient polymerization of cytoplasmatic F-actin (white arrohead), inhibiting polymerization of actin filaments, compared with neighbouring untransfected cells (white arrows). Those mIMCD3 untransfected confluent cells (white arrows) show a normal pattern of stress fibres. (B) Transfection with empty HA or c-myc control plasmids does not disrupt polymerization, and actin filaments are polymerized correctly. Scale bar 20 μm.
