Fig. 2. Myosin VI colocalizes with cortactin, arp2/3 complex and capping protein at the front of individualization complexes. (A-L) Confocal images of spermatids double labeled with Alexa Fluor 488 phalloidin (A,D,G,J) and antibodies to cortactin (B), arp3 (E), ARPC2/p34 (H) or capping protein (K). (M-U) Projections of images of spermatids double labeled with anti-myosin VI antibodies (M,P,S) and antibodies to cortactin (N), arp3 (Q) and capping protein (T).
