FEBS Letters, EarlyView.Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Kyoto Journal of Mathematics, 1952 This note conssits of two rather separated parts. In the first part (§1), we remark a property of homomorphisms of group varieties, and in the second part (§2 and the following), we prove that if a group variety $G$ contains a group subvariety $H$, there exists a non-singular variety $V$ which has $G$ as a group of transformations, and whose points are

Polarizations and Nullcone of Representations of Reductive Groups [PDF]
, 2009 The paper starts with the following simple observation. Let V be a representation of a reductive group G, and let f_1,f_2,...,f_n be homogeneous invariant functions. Then the polarizations of f_1,f_2,...,f_n define the nullcone of k 0} h(t) x = 0 for all

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?
FEBS Letters, EarlyView.This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Barley varieties registered in the Czech Republic in 2007.
Kvasný průmysl, 2007 In 2007 following spring barley malting varieties were registered: Aksamit, Beatrix, Blaník, Poet, Spilka, and Westminster. The varieties Aksamit and Blaník (82.7%; 82.9%) provided malts with very good extract content, for their reduced activity of ...

Twisted forms of toric varieties, their derived categories, and their rationality
, 2020 Toric varieties defined over the complex numbers provide an important testing ground for computing various algebro-geometric invariants (e.g., the coherent derived category associated to a variety), as many computations of interest may be phrased ...

Rigidity for Unirational Groups
, 2021 One of the most fundamental results underlying the theory of abelian varieties is "rigidity" -- that is, that any k-scheme morphism of abelian varieties which preserves identities is actually a k-group homomorphism. This result depends crucially upon the

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.
