Leukocyte Membrane Enzymes Play the Cell Adhesion Game

open access: yesFrontiers in Immunology, 2021
For a long time, proteins with enzymatic activity have not been usually considered to carry out other functions different from catalyzing chemical reactions within or outside the cell.

CHST1 Drives Immunotherapy Resistance in Triple‐Negative Breast Cancer by Orchestrating an Immunosuppressive Microenvironment via the NKRF–CCL20–Macrophage Axis

open access: yesAdvanced Science, EarlyView.
Proposed model of CHST1‐associated immune remodeling in triple‐negative breast cancer. In CHST1‐low tumors, greater nuclear accumulation of NKRF is associated with repression of an NF‐κB‐related CCL20 transcriptional program and an immune‐inflamed microenvironment.

DIXDC1 Promotes Lymphatic Metastasis and Resistance to Cuproptosis in Bladder Cancer Through Mediating DLAT

open access: yesAdvanced Science, EarlyView.
DIXDC1 drives bladder cancer progression by binding and stabilizing DLAT. This axis enhances NEK7 and CCNE2 mRNA stability to promote proliferation and lymphatic metastasis, while limiting copper‐induced DLAT oligomerization to reduce cuproptosis sensitivity, identifying DIXDC1 as a potential target linking metastasis with cuproptosis resistance ...

Functional Crypto-Adenylate Cyclases Operate in Complex Plant Proteins

open access: yesFrontiers in Plant Science, 2021
Adenylyl cyclases (ACs) and their catalytic product cAMP are regulatory components of many plant responses. Here, we show that an amino acid search motif based on annotated adenylate cyclases (ACs) identifies 12 unique Arabidopsis thaliana candidate ACs,

Nuclear IDH3A Drives Transcriptional Programs in Melanoma via the YBX1–JUN/FOS Axis

open access: yesAdvanced Science, EarlyView.
Genomic amplification drives aberrant nuclear localization of IDH3A in melanoma. Independent of its canonical metabolic activity, nuclear IDH3A cooperates with YBX1 to activate the c‐JUN/c‐FOS transcriptional program, while NONO facilitates its nuclear localization.

Protein moonlighting in parasitic protists [PDF]

open access: yesBiochemical Society Transactions, 2014
Reductive evolution during the adaptation to obligate parasitism and expansions of gene families encoding virulence factors are characteristics evident to greater or lesser degrees in all parasitic protists studied to date. Large evolutionary distances separate many parasitic protists from the yeast and animal models upon which classic views of ...

Proteomic Analysis of Sporothrix schenckii Exposed to Oxidative Stress Induced by Hydrogen Peroxide

open access: yesPathogens, 2022
Sporothrix schenckii modulates the expression of its cell wall proteins (CWPs) in response to reactive oxygen species (ROS) generated by the phagocytic cells of the human host, which allows it to evade and escape the immune system.

SAT1‐Induced Spermidine Depletion Potentiates Food Allergy

open access: yesAdvanced Science, EarlyView.
Spermidine depletion, driven by upregulated spermidine/spermine N1‐acetyltransferase (SAT1), potentiates food allergy by promoting mast cell degranulation through autophagy suppression. SAT1 physically interacts with the long noncoding RNA Cdk19os to inhibit Atg5 and Atg7, disrupting autophagic flux.

An evolutionary perspective on protein moonlighting [PDF]

open access: yesBiochemical Society Transactions, 2014
Moonlighting proteins serve one or more novel functions in addition to their canonical roles. Moonlighting functions arise when an adventitious interaction between a protein and a new partner improves fitness of the organism. Selective pressure for improvement in the new function can result in two alternative outcomes.

FBP1‐Mediated Compartmentalization of Glycolytic Enzyme Complexes Suppresses PKM2 Function to Ameliorate MASLD Progression

open access: yesAdvanced Science, EarlyView.
In normal hepatocytes, FBP1 forms compartmentalized complexes with PKM2, ENO1, and LDHA independent of its catalytic activity, inhibiting PKM2 activity and restricting excessive glycolysis. During MASLD progression, FBP1 downregulation markedly reduces the abundance of these complexes and releases the “hijacked” glycolytic enzymes, leading to PKM2 ...
