Researchers have elucidated the molecular mechanisms by which protein phosphatase 2A (PP2A) regulates CD8+ T cell-mediated immune responses. PP2A deficiency impairs T cell effector functions, leading to reduced cytokine production and impaired antiviral responses.
Researchers have discovered that PR55α, a regulatory subunit of PP2A phosphatase, inhibits p16 expression and blocks cellular senescence induction by γ-irradiation. This finding provides a new insight into the regulation of the p16/RB pathway in response to stressors.
Researchers at McGill University discovered that phosphatases of regenerating liver (PRLs) are overexpressed in some cancers, making cells more metastatic and driving disease progression. The study sheds light on PRLs' role in binding magnesium transporters, a common pathway among all studied species.
A research team led by Dr Gary Ying Wai Chan has uncovered a new mechanism that ensures correct DNA segregation in cell division, preventing cancer development. RIF1 and protein phosphatase 1 play a crucial role in resolving ultrafine DNA bridges, which can lead to DNA damage and genome instability if not properly resolved.
A novel inhibitor has been discovered that stalls a critical enzyme inside tumour cells, locking them in place and preventing invasion into healthy tissue. The findings hold promise for the development of metastasis-blocking agents.
Scientists from the University of Pittsburgh have developed two approaches for rendering a specific phosphatase activated by light, allowing them to probe its function. This breakthrough has significant implications for understanding protein-protein interactions and drug discovery, paving the way for new treatments for diseases.
A Finnish-Swiss research team analyzed half of the human protein phosphatome, identifying molecular functions and pathways connecting protein phosphatases. The study reveals phosphatase-based regulation of human cancer and promises therapeutic intervention.
Researchers link abnormal SHP2 signaling to lupus-like symptoms in mice, showing that inhibiting SHP2 improves symptoms and lifespan. Targeting SHP2 in T cells reduces inflammatory cytokine production, suggesting a new therapy approach.
Experts have disabled a unique member of signalling proteins essential for malaria development, arresting its life cycle in the mosquito. This breakthrough discovery could help design new drugs to control malaria transmission.
