Data from: Stoichiometry controls activity of phase-separated clusters of actin signaling proteins

Lindsay B. Case, Xu Zhang, Jonathon A. Ditlev & Michael K. Rosen
Biomolecular condensates concentrate macromolecules into foci without a surrounding membrane. Many condensates appear to form through multivalent interactions that drive liquid-liquid phase separation (LLPS). LLPS increases the specific activity of actin regulatory proteins toward actin assembly by the Arp2/3 complex. We show that this increase occurs because LLPS of the Nephrin–Nck–N-WASP signaling pathway on lipid bilayers increases membrane dwell time of N-WASP and Arp2/3 complex, consequently increasing actin assembly. Dwell time varies with relative stoichiometry...

Data from: Birth-and-death evolution of the fatty acyl-CoA reductase (FAR) gene family and diversification of cuticular hydrocarbon synthesis in Drosophila

Cédric Finet, Kailey Slavik, Jian Pu, Sean B. Carroll & Henry Chung
The birth-and-death evolutionary model proposes that some members of a multigene family are phylogenetically stable and persist as a single copy over time whereas other members are phylogenetically unstable and undergo frequent duplication and loss. Functional studies suggest that stable genes are likely to encode essential functions, while rapidly evolving genes reflect phenotypic differences in traits that diverge rapidly among species. One such class of rapidly diverging traits are insect cuticular hydrocarbons (CHCs), which play...

Data from: Signatures of divergence, invasiveness and terrestralization revealed by four apple snail genomes

Vega, Horacio Heras, Santiago Ituarte, Bert Van Bocxlaer, Kenneth A. Hayes, Robert H. Cowie, Zhongying Zhao, Yu Zhang, Pei-Yuan Qian & Jian-Wen Qiu
The family Ampullariidae includes both aquatic and amphibious apple snails. They are an emerging model for evolutionary studies due to the high diversity, ancient history and wide geographical distribution. Insight into drivers of ampullariid evolution is hampered, however, by the lack of genomic resources. Here we report the genomes of four ampullariids spanning the Old World (Lanistes nyassanus) and New World (Pomacea canaliculata, Pomacea maculata and Marisa cornuarietis) clades. The ampullariid genomes have conserved ancient...

Data from: High-throughput synapse-resolving two-photon fluorescence microendoscopy for deep-brain volumetric imaging in vivo

Guanghan Meng, Yajie Liang, Sarah Sarsfield, Wan-Chen Jiang, Rongwen Lu, Joshua Tate Dudman, Yeka Aponte & Na Ji
Optical imaging has become a powerful tool for studying brains in vivo. The opacity of adult brains makes microendoscopy, with an optical probe such as a gradient index (GRIN) lens embedded into brain tissue to provide optical relay, the method of choice for imaging neurons and neural activity in deeply buried brain structures. Incorporating a Bessel focus scanning module into two-photon fluorescence microendoscopy, we extended the excitation focus axially and improved its lateral resolution. Scanning...
