Mutations of N-terminal cysteines within Pex11pβ do not affect peroxisome membrane elongation.

<p>COS-7 cells were transfected with Pex11pβ-Myc (<b>A–C</b>), Pex11pβ-Myc^C18S-C25S (<b>D–F</b>) and Pex11pβ-Myc^{C18S-C25S-C85S} (<b>G–I</b>), and were processed for immunofluorescence microscopy 24 h after transfection using anti-Myc (<b>A, D, G</b>) and anti-Pex14p (<b>B, E, H</b>) antibodies. (<b>J</b>) Quantitative evaluation of peroxisome morphology. Data are from 3 independent experiments and are presented as means ± S.D. Bars, 20 µm.
