Amino acid residues 24-31 but not palmitoylation of cysteines 30 and 45 are required for membrane anchoring of glutamic acid decarboxylase, GAD65. [PDF]
The smaller isoform of the GABA synthesizing enzyme glutamic acid decarboxylase, GAD65, is synthesized as a soluble protein that undergoes post-translational modification(s) in the NH2-terminal region to become anchored to the membrane of small synaptic ...

miR-9 and miR-124 synergistically affect regulation of dendritic branching via the AKT/GSK3β pathway by targeting Rap2a [PDF]
A single microRNA (miRNA) can regulate expression of multiple proteins, and expression of an individual protein may be controlled by numerous miRNAs.

CD9‐association with PIP2 areas is regulated by a CD9 salt bridge
The tetraspanin CD9 has an intracellular salt bridge. If CD9 opens, open‐CD9 moves from PIP2‐rich areas to regions populated by its interaction partner EWI‐2. Hence, the state of the salt bridge regulates the distribution of CD9 and by this CD9‐EWI‐2 complex formation.

Quantitative analysis of the human T cell palmitome [PDF]
Palmitoylation is a reversible post-translational modification used to inducibly compartmentalize proteins in cellular membranes, affecting the function of receptors and intracellular signaling proteins.

This study identifies ZDHHC12 as a critical mediator of PA‐induced HCC progression. Mechanistically, PA upregulates ZDHHC12 expression through SMARCA4 activation, leading to HDAC8 palmitoylation at Cys244 which blocks HSC70‐mediated lysosomal degradation of HDAC8, thereby promoting HCC development. These findings provide novel mechanistic insights into

Dominant Role of Oncogene Dosage and Absence of Tumor Suppressor Activity in Nras-Driven Hematopoietic Transformation [PDF]
Biochemical properties of Ras oncoproteins and their transforming ability strongly support a dominant mechanism of action in tumorigenesis. However, genetic studies unexpectedly suggested that wild-type (WT) Ras exerts tumor suppressor activity ...

ABSTRACT Proteomics of laser‐dissected lipofuscin from aged, healthy brains reveals Palmitoyl‐Protein Thioesterase 1 (PPT1) and other CLN proteins as constituents. PPT1 is increasingly sequestered to lipofuscin during ageing. Protein sequestering into lipofuscin may contribute to physiological neuronal ageing.

Palmitoylation of human proteinase-activated receptor-2 differentially regulates receptor-triggered ERK1/2 activation, calcium signalling and endocytosis [PDF]
hPAR2 (human proteinase-activated receptor-2) is a member of the novel family of proteolytically activated GPCRs (G-protein-coupled receptors) termed PARs (proteinase-activated receptors).

IPA is an intestinal tryptophan metabolite whose effects decline with decreased heart function. Supplementing IPA can alleviate the aging‐related myocardial fibrosis through PPT1. PPT1 is a key protein localized to lysosomes, and IPA can restore macrophage autophagy function by regulating PPT1 expresssions, thereby reducing aging‐related myocardial ...

Enhancing Gpx1 palmitoylation to inhibit angiogenesis by targeting PPT1
The significance of protein S-palmitoylation in angiogenesis has been largely overlooked, leaving various aspects unexplored. Recent identification of Gpx1 as a palmitoylated protein has generated interest in exploring its potential involvement in novel ...
