The cryo-EM structure of the human Arp2/3 ARPC1B-ARPC5L complex. (A) Left, overview of the cryo-EM reconstruction of Arp2/3-C1B-C5L with the docked model in the density, viewed and coloured as originally presented by Robinson et al. (2001): Arp2: red; Arp3: orange; ARPC1B: green; ARPC2: cyan; ARPC3: magenta; ARPC4: light blue; ARPC5L: yellow; right, same view of the reconstruction with a ∼8 Å low-pass filter applied showing more flexible regions of the complex at lower resolution; (B) left, 180° rotated view compared to A of the Arp2/3-C1B-C5L reconstruction and model; right, same view of the reconstruction with a ∼8 Å low-pass filter applied showing more flexible regions of the complex at lower resolution, which includes flexible connectivity between Arp2 and Arp3 (red arrow) and parts of ARPC5L. sd, subdomains of Arp2.
