AMP-activated Protein Kinase (AMPK): New molecular insights and novel downstream targets

Katyayanee Neopane

AMP-activated Protein Kinase (AMPK) is a central regulator of energy homeostasis and a promising drug target for metabolic disorders. It exists as complexes of three subunits, a catalytic alpha, and two regulatory beta and gamma subunits. The regulation of ...

Receptor-independent modulation of cAMP-dependent protein kinase and protein phosphatase signaling in cardiac myocytes by oxidizing agents

Sonia Donzelli

The contraction and relaxation of the heart is controlled by stimulation of the beta 1-adrenoreceptor (AR) signaling cascade, which leads to activation of cAMP-dependent protein kinase (PKA) and subsequent cardiac protein phosphorylation. Phosphorylation i ...

Allosteric regulation and targeting of Bruton's tyrosine kinase (Btk) in B-cell lymphoma

Daniel Pereira Duarte

Bruton's tyrosine kinase (Btk) is a key component of BCR signaling required for B-cell maturation and activation. Loss-of-function mutations throughout the Btk protein cause human X-linked agammaglobulinemia (XLA), a heritable genetic disorder characterize ...

Btk SH2-kinase interface is critical for allosteric kinase activation and its targeting inhibits B-cell neoplasms

Florence Pojer, Matteo Dal Peraro, Oliver Hantschel, Sandrine Madeleine Suzanne Georgeon, Allan Joaquim Lamontanara, Tim Kükenshöner, Maria Josefina Marcaida Lopez, Daniel Pereira Duarte, Grégory La Sala

Bruton's tyrosine kinase (Btk) is critical for B-cell maturation and activation. Btk loss-of-function mutations cause human X-linked agammaglobulinemia (XLA). In contrast, Btk signaling sustains growth of several B-cell neoplasms which may be treated with ...

Live imaging screen reveals that TYRO3 and GAK ensure accurate spindle positioning in human cells

Pierre Gönczy, Coralie Busso, Benita Wolf

Proper spindle positioning is crucial for spatial cell division control. Spindle positioning in human cells relies on a ternary complex comprising G alpha i1-3, LGN and NuMA, which anchors dynein at the cell cortex, thus enabling pulling forces to be exert ...

Identification of novel PCTAIRE-1/CDK16 substrates using a chemical genetic screen

Maria Deak, Kei Sakamoto, Caterina Collodet

PCTAIRE-1 (also known as cyclin-dependent protein kinase (CDK) 16), is a Ser/Thr kinase that has been implicated in many cellular processes, including cell cycle, spermatogenesis, neurite outgrowth, and vesicle trafficking. Most recently, it has been propo ...
