    Polo-like kinase-dependent phosphorylation of the synaptonemal complex protein SYP-4 regulates double-strand break formation through a negative feedback loop.

    Saravanapriah Nadarajan et al.
    PLK-1/2-mediated SYP-4 phosphorylation is dependent on crossover precursor formation, triggering a switch in the dynamic state of the synaptonemal complex that reduces the formation of further double-strand breaks at late meiotic prophase.

    The GIRK1 subunit potentiates G protein activation of cardiac GIRK1/4 hetero-tetramers

    Kouki K Touhara et al.
    The GIRK1 subunit contains a defective Na+-binding site but behaves as if it is permanently bound to a sodium ion, and therefore increases the affinity of Gβγ to GIRK1/4 hetero-tetrameric channels in lipid membranes.
