Nucleation, Stabilization and Disassembly of Branched Actin Networks

Trends in Cell Biology, 2021
Arp2/3 complex is an actin filament nucleation and branching machinery conserved in all eukaryotes from yeast to human. Arp2/3 complex branched networks generate pushing forces that drive cellular processes ranging from membrane remodeling to cell and ...

Branched Setae or Attached Macroalgae: A Case Study of an Exceptionally Preserved Brachiopod from the Early Cambrian Chengjiang Lagerstätte

Biology
The remarkable conservation of soft tissues within Cambrian fossils has significantly enhanced our comprehension of the origins and evolutionary trajectories of animals, in addition to the progression of ecological intricacy.

Branch-Well-Structured Transition Systems and Extensions

Logical Methods in Computer Science, 2022
We propose a relaxation to the definition of well-structured transition systems (\WSTS) while retaining the decidability of boundedness and non-termination. In this class, the well-quasi-ordered (wqo) condition is relaxed such that it is applicable only between states that are reachable one from another.

Structure of the branched intermediate in protein splicing [PDF]

Proceedings of the National Academy of Sciences, 2014
Significance We report the crystal structure of an intein poised to carry out the rate-limiting step in protein splicing, namely the attack of a conserved Asn side-chain amide on the adjacent backbone amide, leading to resolution of the branched intermediate in the process.

Structural basis of K11/K48-branched ubiquitin chain recognition by the human 26S proteasome

Nature Communications
Beyond the canonical K48-linked homotypic polyubiquitination for proteasome-targeted proteolysis, K11/K48-branched ubiquitin (Ub) chains are involved in fast-tracking protein turnover during cell cycle progression and proteotoxic stress.

Statistical polymer method: Modeling of macromolecules and aggregates with branching and crosslinking, formed in random processes

Discrete Dynamics in Nature and Society, 1998
The statistical polymer method is based on the consideration of averaged structures of all possible macromolecules of the same weight. One has derived equations allowing evaluation of all additive parameters of macromolecules and their systems.

Transport-generated signals uncover geometric features of evolving branched structures

Physical Review Research
Branched structures that evolve over time critically shape the function of diverse natural and engineered systems, from neuronal dendrites and vascular networks to pulmonary and root architectures.
