    Small molecule induced oligomerization, clustering and clathrin-independent endocytosis of the dopamine transporter

    Tatiana Sorkina et al.
    Dopamine transporter (DAT) interaction with furopyrimidine called AIM-100 in intact cells leads to dramatic oligomerization, nanoclustering and endocytosis of DAT by a novel mechanism coupled to the transporter molecule conformation.

    Structure analyses reveal a regulated oligomerization mechanism of the PlexinD1/GIPC/myosin VI complex

    Guijun Shang et al.
    PlexinD1 binding releases GIPC autoinhibition, leading to formation of high-order oligomers of the GIPC/myosin VI complex.

    The homo-oligomerisation of both Sas-6 and Ana2 is required for efficient centriole assembly in flies

    Matthew A Cottee et al.
    The structure of the Ana2 Central Coiled-Coil Domain provides insight into how centriolar cartwheel components may be recruited and assembled, and indicates that cartwheel assembly involves more than just SAS-6 oligomerisation.

    Oligomerization of p62 allows for selection of ubiquitinated cargo and isolation membrane during selective autophagy

    Bettina Wurzer et al.
    Oligomerization of p62/SQSTM1 generates high avidity binding regions that enable it to spatially select for concentrated ubiquitin and ATG8-family proteins.

    Oligomerization of a molecular chaperone modulates its activity

    Tomohide Saio et al.
    A combined NMR and kinetic study demonstrates how the dynamic transition of a molecular chaperone between different oligomerization states can modulate its activity by altering the binding kinetics and energetics of non-native proteins.

    Phosphoinositide-mediated oligomerization of a defensin induces cell lysis

    Ivan KH Poon et al.
    A novel innate defense mechanism of cell lysis involves the coordinated oligomerization of a defensin by interaction with the membrane lipid, phosphatidylinositol 4,5-bisphosphate.

    Structural basis of host recognition and biofilm formation by Salmonella Saf pili

    Longhui Zeng et al.
    SafDAA-SafDAA structure and functional characterizations reveal a pili-mediated inter-cellular oligomerization mechanism for bacterial aggregation and biofilm formation in Salmonella enterica.

    Physiological modulation of BiP activity by trans-protomer engagement of the interdomain linker

    Steffen Preissler et al.
    Interdomain linker-mediated oligomerization of the endoplasmic reticulum chaperone protein BiP responds to the unfolded protein burden

    Circular oligomerization is an intrinsic property of synaptotagmin

    Jing Wang et al.
    Calcium-binding synaptotagmins are involved in ring oligomer formation, which allows synaptotagmins to synchronize neurotransmitter release to Ca2+ influx.

    The microtubule polymerase Stu2 promotes oligomerization of the γ-TuSC for cytoplasmic microtubule nucleation

    Judith Gunzelmann et al.
    Biochemical and genetic approaches show that the XMAP215 homolog Stu2 directly interacts with the small gamma-tubulin complex and its recruitment factor Spc72 to instigate functions in cytoplasmic microtubule organization.
