    AMPK and vacuole-associated Atg14p orchestrate μ-lipophagy for energy production and long-term survival under glucose starvation

    Arnold Y Seo, Pick-Wei Lau ... Jennifer Lippincott-Schwartz
    Upon AMPK activation by acute glucose restriction, Atg14p shifts its distribution from ER exit sites to liquid-ordered membrane domains on the vacuolar surface where, together with Atg6p, it facilitates LD-specific autophagy (i.e., microautophagy of lipid droplets) for energy production and long-term survival of starved cells.

    ESCRT-III activation by parallel action of ESCRT-I/II and ESCRT-0/Bro1 during MVB biogenesis

    Shaogeng Tang, Nicholas J Buchkovich ... Scott D Emr
    Building on previous work (Tang et al., 2015), novel ESCRT-III subunit Snf7 auto-activation mutants are used to reveal two parallel ubiquitin-dependent pathways during multivesicular endosome biogenesis.

    Structural basis for recognition and remodeling of the TBP:DNA:NC2 complex by Mot1

    Agata Butryn, Jan M Schuller ... Karl-Peter Hopfner
    A structural analysis of the transcription regulator Mot1 in complex with promoter DNA and the proteins TBP and NC2 provides a first structural framework for how a Swi2/Snf2 type remodeler interacts with a histone fold protein:DNA complex.

    P2RY14 cAMP signaling regulates Schwann cell precursor self-renewal, proliferation, and nerve tumor initiation in a mouse model of neurofibromatosis

    Jennifer Patritti Cram, Jianqiang Wu ... Nancy Ratner
    In a mouse model of neurofibromatosis type 1, the purinergic receptor P2RY14 is a key regulator of Schwann cell precursor self-renewal and proliferation, of neurofibroma tumor initiation and of mouse survival.
