Rajagopal V, Seiler J, Nasa I, Cantarella S, Theiss J, Herget F, et al.
Nat Commun
. 2025 Mar;
16(1):2325.
PMID: 40057470
Ribonucleoprotein complexes are dynamic assemblies of RNA with RNA-binding proteins, which modulate the fate of RNA. Inversely, RNA riboregulates the interactions and functions of the associated proteins. Dysregulation of ribonucleoprotein...

bioRxiv
. 2025 Feb;
PMID: 39990307
Serine/Threonine phosphoprotein phosphatases (PPPs, PP1-PP7) are conserved metalloenzymes and central to intracellular signaling in eukaryotes, but the details of their regulation is poorly understood. To address this, we performed genome-wide...

J Neurosci
. 2025 Jan;
45(11).
PMID: 39837661
Microglia respond to cytotoxic protein aggregates associated with the progression of neurodegenerative disease. Pathological protein aggregates activate the microglial NLRP3 inflammasome resulting in proinflammatory signaling, secretion, and potentially pyroptotic cell...

Cancer Res
. 2025 Jan;
85(6):1145-1161.
PMID: 39777474
Despite adjuvant treatment with endocrine therapies, estrogen receptor-positive (ER+) breast cancers recur in a significant proportion of patients. Recurrences are attributable to clinically undetectable endocrine-tolerant persister cancer cells that retain...

Int J Cancer
. 2024 Dec;
156(6):1191-1202.
PMID: 39635770
Triple-negative breast cancer (TNBC) is the most aggressive breast cancer subtype with substantial disease heterogeneity, limited treatment options, and dismal clinical outcomes. Some TNBCs display homologous recombination deficiency (HRD), a...

Mol Cell
. 2024 Nov;
84(24):4843-4861.e8.
PMID: 39603239
Gene expression is regulated by controlling distinct steps of the transcriptional cycle, including initiation, pausing, elongation, and termination. Kinases phosphorylate RNA polymerase II (RNA Pol II) and associated factors to...

Nat Commun
. 2024 Nov;
15(1):9822.
PMID: 39537675
Protein Ser/Thr phosphatase PP1 is always associated with one or two regulatory subunits or RIPPOs. One of the earliest evolved RIPPOs is PPP1R2, also known as Inhibitor-2. Since its discovery...

. 2024 Nov;
7(1):1473.
PMID: 39516273
Plk1 is a key mitotic kinase that localizes to distinct subcellular structures to promote accurate mitotic progression. Plk1 recruitment depends on direct interaction between polo-box domain (PBD) on Plk1 and...

PMID: 39446389
Phosphoprotein phosphatases (PPPs) are the key serine/threonine phosphatases that regulate all essential signaling cascades. In particular, Protein Phosphatase 1 (PP1) dephosphorylates ~80% of all ser/thr phosphorylation sites. Here, we developed...

. 2024 Oct;
PMID: 39386702
Ribonucleoprotein complexes are dynamic assemblies of RNA with RNA-binding proteins (RBPs), which can modulate the fate of the RNA molecules from transcription to degradation. Vice versa, RNA can regulate the...
