    The Calcineurin-FoxO-MuRF1 signaling pathway regulates myofibril integrity in cardiomyocytes

    Hirohito Shimizu et al.
    Calcium overload in cardiomyocytes disrupts sarcomere integrity, by stimulating transcriptional upregulation of the E3 ubiquitin ligase MuRF1.

    Requirement of Smurf-mediated endocytosis of Patched1 in sonic hedgehog signal reception

    Shen Yue et al.
    Smurf1 and Smurf2 have essential functions in the mammalian Shh signaling pathway, binding to and ubiquitylating Patched1, leading to its endocytosis and subsequent degradation in lysosomes.

    The cargo receptor SURF4 promotes the efficient cellular secretion of PCSK9

    Brian T Emmer et al.
    A CRISPR-based genomic screen identifies the ER cargo receptor SURF4 as a key determinant in the secretion of PCSK9, a protein that regulates human cholesterol levels and cardiovascular disease risk.

    Molecular structure of human KATP in complex with ATP and ADP

    Kenneth Pak Kin Lee et al.
    MgADP binding to the high-affinity 'consensus' ATPase active site of SUR1 and remodeling of the L0-loop (lasso region) overrides tonic ATP inhibition of KATP channels.

    Two locus inheritance of non-syndromic midline craniosynostosis via rare SMAD6 and common BMP2 alleles

    Andrew T Timberlake et al.
    Epistatic interactions of rare loss of function mutations in SMAD6 and a common variant modifier near BMP2 are the most common cause of midline craniosynostosis in humans.

    Transcriptional activator TAp63 is upregulated in muscular atrophy during ALS and induces the pro-atrophic ubiquitin ligase Trim63

    Yannick von Grabowiecki et al.
    Atrophic muscles of patients and animal models developing amyotrophic lateral sclerosis show an upregulation of TAp63 that stimulates the expression of a pro-atrophic ubiquitin ligase.

    Mechanism of pharmacochaperoning in a mammalian KATP channel revealed by cryo-EM

    Gregory M Martin et al.
    Diverse KATP channel inhibitors occupy a common binding pocket and stabilize an interaction between Kir6.2 and SUR1 to allosterically control gating and promote the assembly and trafficking of nascent channels.

    Ion Channels: From ions to insulin

    Voula Kanelis
    Electron cryo-microscopy has revealed the three-dimensional structure of a potassium channel that has a central role in regulating the release of insulin from the pancreas.

    The complex of TRIP-Br1 and XIAP ubiquitinates and degrades multiple adenylyl cyclase isoforms

    Wenbao Hu et al.
    XIAP/TRIP-Br1-mediated degradation of multiple adenylyl cyclase isoforms is a previously unrecognised general mechanism for controlling adenylyl cyclase expression and the homeostasis of cAMP signalling.
