Immunofluorescence images of cells expressing (A) Myo21-GFP, (B) Myo21UBAs-GFP, (C) Myo21UBA1-GFP, and (D) Myo21UBA2-GFP, GENZ-882706 labeled for actin (reddish). Myo21-GFP protein co-localizes with actin in the cell body, flagellum and also in the proximal region of the flagellum. However, Myo21UBAs-GFP co-localized with actin in the cell body but virtually no co-distribution of these proteins could be seen in the flagellum, including its proximal region. Like Myo21UBAs-GFP protein, Myo21UBA1-GFP and Myo21UBA2-GFP also failed to co-distribute with actin in the flagellum. Quantity of cells imaged for co-localization of GFP tagged protein with actin for Myo21-GFP- ~20, Myo21UBAs-GFP~18, Myo21UBA1-GFP- ~19 and Myo21UBA2-GFP- ~14 in at least three self-employed experiments. Arrowheads show co-distribution of Myo21-GFP with actin in the flagellum.
