  text: The differentiation of cells depends on a precise control of their internal
    organization, which is the result of a complex dynamic interplay between the cytoskeleton,
    molecular motors, signaling molecules, and membranes. For example, in the developing
    neuron, the protein ADAP1 (ADP-ribosylation factor GTPase-activating protein [ArfGAP]
    with dual pleckstrin homology [PH] domains 1) has been suggested to control dendrite
    branching by regulating the small GTPase ARF6. Together with the motor protein
    KIF13B, ADAP1 is also thought to mediate delivery of the second messenger phosphatidylinositol
    (3,4,5)-trisphosphate (PIP3) to the axon tip, thus contributing to PIP3 polarity.
    However, what defines the function of ADAP1 and how its different roles are coordinated
    are still not clear. Here, we studied ADAP1’s functions using in vitro reconstitutions.
    We found that KIF13B transports ADAP1 along microtubules, but that PIP3 as well
    as PI(3,4)P2 act as stop signals for this transport instead of being transported.
    We also demonstrate that these phosphoinositides activate ADAP1’s enzymatic activity
    to catalyze GTP hydrolysis by ARF6. Together, our results support a model for
    the cellular function of ADAP1, where KIF13B transports ADAP1 until it encounters
    high PIP3/PI(3,4)P2 concentrations in the plasma membrane. Here, ADAP1 disassociates
    from the motor to inactivate ARF6, promoting dendrite branching.

  text: Growing microtubules are protected from depolymerization by the presence of
    a GTP or GDP/Pi cap. End-binding proteins of the EB1 family bind to the stabilizing
    cap, allowing monitoring of its size in real time. The cap size has been shown
    to correlate with instantaneous microtubule stability. Here we have quantitatively
    characterized the properties of cap size fluctuations during steadystate growth
    and have developed a theory predicting their timescale and amplitude from the
    kinetics of microtubule growth and cap maturation. In contrast to growth speed
    fluctuations, cap size fluctuations show a characteristic timescale, which is
    defined by the lifetime of the cap sites. Growth fluctuations affect the amplitude
    of cap size fluctuations; however, cap size does not affect growth speed, indicating
    that microtubules are far from instability during most of their time of growth.
    Our theory provides the basis for a quantitative understanding of microtubule
    stability fluctuations during steady-state growth.

  text: The human cerebral cortex is the seat of our cognitive abilities and composed
    of an extraordinary number of neurons, organized in six distinct layers. The establishment
    of specific morphological and physiological features in individual neurons needs
    to be regulated with high precision. Impairments in the sequential developmental
    programs instructing corticogenesis lead to alterations in the cortical cytoarchitecture
    which is thought to represent the major underlying cause for several neurological
    disorders including neurodevelopmental and psychiatric diseases. In this review
    we discuss the role of cell polarity at sequential stages during cortex development.
    We first provide an overview of morphological cell polarity features in cortical
    neural stem cells and newly-born postmitotic neurons. We then synthesize a conceptual
    molecular and biochemical framework how cell polarity is established at the cellular
    level through a break in symmetry in nascent cortical projection neurons. Lastly
    we provide a perspective how the molecular mechanisms applying to single cells
    could be probed and integrated in an in vivo and tissue-wide context.

  text: Most kinesin motors move in only one direction along microtubules. Members
    of the kinesin-5 subfamily were initially described as unidirectional plus-end-directed
    motors and shown to produce piconewton forces. However, some fungal kinesin-5
    motors are bidirectional. The force production of a bidirectional kinesin-5 has
    not yet been measured. Therefore, it remains unknown whether the mechanism of
    the unconventional minus-end-directed motility differs fundamentally from that
    of plus-end-directed stepping. Using force spectroscopy, we have measured here
    the forces that ensembles of purified budding yeast kinesin-5 Cin8 produce in
    microtubule gliding assays in both plus- and minus-end direction. Correlation
    analysis of pause forces demonstrated that individual Cin8 molecules produce additive
    forces in both directions of movement. In ensembles, Cin8 motors were able to
    produce single-motor forces up to a magnitude of ∼1.5 pN. Hence, these properties
    appear to be conserved within the kinesin-5 subfamily. Force production was largely
    independent of the directionality of movement, indicating similarities between
    the motility mechanisms for both directions. These results provide constraints
    for the development of models for the bidirectional motility mechanism of fission
    yeast kinesin-5 and provide insight into the function of this mitotic motor.

  text: Microtubules switch stochastically between phases of growth and shrinkage.
    The molecular mechanism responsible for the end of a growth phase, an event called
    catastrophe, is still not understood. The probability for a catastrophe to occur
    increases with microtubule age, putting constraints on the possible molecular
    mechanism of catastrophe induction. Here we used microfluidics-Assisted fast tubulin
    washout experiments to induce microtubule depolymerization in a controlled manner
    at different times after the start of growth. We found that aging can also be
    observed in this assay, providing valuable new constraints against which theoretical
    models of catastrophe induction can be tested. We found that the data can be quantitatively
    well explained by a simple kinetic threshold model that assumes an age-dependent
    broadening of the protective cap at the microtubule end as a result of an evolving
    tapered end structure; this leads to a decrease of the cap density and its stability.
    This analysis suggests an intuitive picture of the role of morphological changes
    of the protective cap for the age dependence of microtubule stability.
