Identification of phosphorylation sites on purified recombinant protein Dynamin-like protein 1

ABSTRACT: Drp1 is a GTPase involves in mitochondrial division. The phosphorylation of Drp1 is reported to influence Drp1 activity. Two well known Drp1 phosphorylation sites have been identified. In here, we in vitro phosphorylate S579 site by ERK2 kinase on WT-Drp1 or S600D-Drp1 mutant and try to identify the phosphorylation by Mass Spec.

Effects of phosphorylation on Drp1 activation by its receptors, actin, and cardiolipin.

Molecular biology of the cell 20231129 2

Drp1 is a dynamin family GTPase required for mitochondrial and peroxisomal division. Oligomerization increases Drp1 GTPase activity through interactions between neighboring GTPase domains. In cells, Drp1 is regulated by several factors including Drp1 receptors, actin filaments, cardiolipin, and phosphorylation at two sites: S579 and S600. Commonly, phosphorylation of S579 is considered activating, while S600 phosphorylation is considered inhibiting. However, direct effects of phosphorylation on ...[more]

Project description:Development of cancer is intimately associated with genetic abnormalities that target proteins with intrinsically disordered regions (IDRs). In human hematological malignancies, recurrent chromosomal translocation of nucleoporin (NUP98 or NUP214) generates an aberrant chimera that invariably retains nucleoporin’s IDR, tandemly dispersed phenylalanine-andglycine (FG) repeats1-3. However, it remains largely elusive how unstructured IDRs contribute to oncogenesis. We here show that IDR or FG repeats harbored within NUP98-HOXA9, a homeodomain-containing transcription factor (TF) chimera recurrently detected in acute leukemia patients1,4,5, is essential for establishing nuclear liquid-liquid phase separation (LLPS) puncta and for inducing leukemic transformation of primary hematopoietic cells in vitro and in vivo. Strikingly, LLPS of NUP98-HOXA9 not only promotes chromatin occupancy of chimera TF oncoproteins but is also required for formation of a broad, ‘super-enhancer’-like binding pattern, typically seen at a battery of leukemia-related loci exemplified by HOX, MEIS and PBX genes, potentiating their transcriptional activation. An artificial HOX chimera, created by replacing NUP98’s FG repeats with an unrelated LLPSforming IDR of FUS6,7, had similar enhancement effects on chimera’s chromatin binding and target gene activation. Via Hi-C mapping, we further demonstrated that the phase-separated NUP98-HOXA9 protein assembly is able to induce formation of CTCF-independent chromatin looping enriched at leukemic oncogenes. Together, this report describes a proof-of-principle example wherein cancer acquires mutation to establish condensates of oncogenic TFs via a phase separation mechanism, which simultaneously enhances their chromatin targeting and induces organization of aberrant three-dimensional chromatin structure during tumorous transformation. As a range of LLPS-competent molecules are implicated in various human cancers, this mechanism can potentially be generalized to many malignant and diseased settings.

Project description:The staphylococcal accessory regulator A (sarA) impacts the extracellular accumulation of Staphylococcus aureus virulence factors at the level of intracellular production and extracellular protease-mediated degradation. To assess the relative impact of these two functions, we previously used a proteomics approach that measures protein abundance as a function of all proteoforms to demonstrate that mutation of sarA results in increased levels of extracellular proteases and assess the impact of this on the accumulation of S. aureus exoproteins1. While this approach confirmed that protease-mediated degradation has a significant impact on the S. aureus exoproteome, it was potentially limited in that it did not take into account the possibility that large, stable proteolytic products from a given protein could result in false negatives when quantified by total proteoforms. Here, we present an expanded proteomics approach that utilizes a dual quantitative method for measuring abundance at both the total proteoform and full-length exoprotein levels. Specifically, proteins present in conditioned medium from overnight, stationary phase cultures of the USA300 strain LAC, an isogenic sarA mutant, and a sarA mutant unable to produce any of the known extracellular proteases (sarA/protease) were resolved using one-dimensional gel electrophoresis. Using methods that focus on total proteoforms vs. methods that focus specifically on full-length proteins, quantitative proteomic comparisons of sarA vs sarA/protease mutants identified proteins that were degraded in a protease dependent manner owing to mutation of sarA, while comparisons of a sarA/protease mutant vs the LAC parent strain identified proteins in which abundance was altered in a sarA mutant in a protease-independent manner. Furthermore, the proteins uniquely identified by the full-length data analysis approach eliminated false negatives observed in the total proteoform analysis. This approach provided for a more comprehensive and robust analysis of the impact of mutating sarA and protease-mediated degradation on the S. aureus exoproteome.
