    Brain clusterin protein isoforms and mitochondrial localization

    Sarah K Herring et al.
    Identification and characterization of multiple brain clusterin isoforms, including a mitochondrial matrix-targeted isoform, provides foundation to potentially clarify the link between these proteins and the development of late-onset Alzheimer’s disease.

    Phase transitions of multivalent proteins can promote clustering of membrane receptors

    Sudeep Banjade, Michael K Rosen
    A new and general mechanism describes the organization of membrane proteins and their cytoplasmic ligands into micrometer-scale clusters, based on polymerization and concomitant phase separation of multivalent proteins.

    Shed EBA-175 mediates red blood cell clustering that enhances malaria parasite growth and enables immune evasion

    May M Paing et al.
    Plasmodium falciparum invasion protein EBA-175, once shed from the parasite surface post invasion, facilitates RBC clustering and enhances parasite growth while simultaneously enabling parasite immune evasion of host neutralizing antibodies.

    Clarinet (CLA-1), a novel active zone protein required for synaptic vesicle clustering and release

    Zhao Xuan et al.
    Clarinet, a novel C. elegans active zone protein with homology to vertebrate Piccolo and Rim, uses its different isoforms for diverse functions, including synaptic vesicle clustering, vesicle release and synaptogenesis.

    Asymmetric clustering of centrosomes defines the early evolution of tetraploid cells

    Nicolaas C Baudoin et al.
    Newly formed tetraploid cells rapidly lose extra centrosomes acquired upon tetraploidization via asymmetric centrosome clustering during cell division and selective advantage of tetraploid daughter cells that inherit a single centrosome.

    Inference of nonlinear receptive field subunits with spike-triggered clustering

    Nishal P Shah et al.
    Nonlinear receptive field subunits in retinal ganglion cells are isolated and characterized by clustering spike-triggered stimuli, and validated on population responses to naturalistic and novel closed loop stimuli.

    Lamellipodin promotes actin assembly by clustering Ena/VASP proteins and tethering them to actin filaments

    Scott D Hansen, R Dyche Mullins
    Lamellipodin, an important regulator of cytoskeletal and assembly cell migration, enhances the activity of Ena/VASP family actin polymerases by clustering them on leading-edge membranes and tethering them to actin filaments.

    RNA Polymerase II cluster dynamics predict mRNA output in living cells

    Won-Ki Cho et al.
    Quantitative super resolution imaging, in live mammalian cells, reveals a direct relationship between protein clustering dynamics and the number of mRNA transcribed at an endogenous gene locus.

    Functional clustering of dendritic activity during decision-making

    Aaron Kerlin et al.
    In motor cortex pyramidal neurons, diverse task-related signals are distributed throughout the dendritic arbor and compartmentalized by dendritic distance and branching.

    Translational regulation of protrusion-localized RNAs involves silencing and clustering after transport

    Konstadinos Moissoglu et al.
    RNAs enriched at cell protrusions are translated regardless of their location in the cytoplasm but are dynamically repressed in retracting protrusions and incorporated into heterogeneous RNA clusters.
