    Identification and dynamics of the human ZDHHC16-ZDHHC6 palmitoylation cascade

    Laurence Abrami et al.
    Cycles of palmitoylation-depalmitoylation by an upstream palmitoyltransferase allow precise tuning of DHHC6 activity, which in turn regulates the abundance and function of key ER proteins involved in protein folding, degradation, ER architecture and calcium homeostasis.

    Massive endocytosis triggered by surface membrane palmitoylation under mitochondrial control in BHK fibroblasts

    Donald W Hilgemann et al.
    Mitochondria can trigger massive endocytosis by releasing coenzyme A into the cytoplasm and thereby promoting the addition of fatty acids to surface membrane proteins.

    Palmitoylation of LIM Kinase-1 ensures spine-specific actin polymerization and morphological plasticity

    Joju George et al.
    The protein-lipid modification palmitoylation targets the kinase LIMK1 to dendritic spines to ensure precise control of the size of individual spines in response to synaptic activation.

    Massive palmitoylation-dependent endocytosis during reoxygenation of anoxic cardiac muscle

    Mei-Jung Lin et al.
    Reoxygenation of anoxic cardiac tissue promotes massive endocytosis that is triggered by release of coenzymeA from mitochondria, followed by palmitoylation of membrane proteins, sarcolemma vesiculation, and transfer of sarolemma vesicles to large endosomes and vacuoles.

    The palmitoyl acyltransferase ZDHHC14 controls Kv1-family potassium channel clustering at the axon initial segment

    Shaun S Sanders et al.
    ZDHHC14 controls palmitoylation and axon initial segment targeting of PSD93 and Kv1-family potassium channels, events that are essential for normal neuronal excitability.

    Developmental NMDA receptor dysregulation in the infantile neuronal ceroid lipofuscinosis mouse model

    Kevin P Koster et al.
    NMDA receptor function is regulated by protein depalmitoylation during visual cortical maturation and is dysfunctional in infantile neuronal ceroid lipofuscinosis.

    Wnt5a signaling induced phosphorylation increases APT1 activity and promotes melanoma metastatic behavior

    Rochelle Shirin Sadeghi et al.
    Phosphorylation of serine residues 209 and 210 on APT1 increases its depalmitoylating activity, promoting Wnt5a mediated melanoma cell invasion.

    Oxaliplatin resistance in colorectal cancer enhances TRAIL sensitivity via death receptor 4 upregulation and lipid raft localization

    Joshua D Greenlee et al.
    Oxaliplatin-resistant colorectal cancer cells exhibit unregulated death receptor 4 expression with increased receptor palmitoylation and translocation into lipid rafts, increasing their sensitivity to apoptosis via TRAIL.

    ABHD17 proteins are novel protein depalmitoylases that regulate N-Ras palmitate turnover and subcellular localization

    David Tse Shen Lin, Elizabeth Conibear
    Palmitate turnover is controlled by distinct enzyme families with different specificities.

    Glycine acylation and trafficking of a new class of bacterial lipoprotein by a composite secretion system

    Christopher Icke et al.
    AatD is a novel acyltransferase that mediates N-palmitoylation of glycine, a process not previously described, that results in the secretion of lipoproteins to the bacterial cell surface.
