A completeness criterion for the common divisor graph on p -regular class sizes
Communications in AlgebraLet $G$ be a finite group. For some fixed prime $p$, let $Γ_p(G)$ be the common divisor graph built on the set of sizes of $p$-regular conjugacy classes of $G$: this is the simple undirected graph whose vertices are the class sizes of those non-central elements of $G$ such that $p$ does not divide their order, and two distinct vertices are adjacent if ...

Evolution‐guided yeast complementation reveals functional differences in human PSPH variants
FEBS Open Bio, EarlyView.Ancient genomes can help guide which human genetic variants are tested experimentally. This study applies that idea to PSPH, a gene involved in serine biosynthesis, and uses high‐throughput yeast complementation to compare variant function. The findings reveal measurable differences among selected alleles and illustrate the value of evolution‐guided ...

Adenosine triphosphate as a modulator of protein interactions and stability
FEBS Open Bio, EarlyView.ATP is best known as the cell's energy currency, but it also shapes how proteins fold, interact, aggregate and form biomolecular condensates. This review explains the emerging physical principles behind these effects, including weak binding to charged protein regions, magnesium‐dependent behaviour and concentration‐dependent control of protein ...

Le Matematiche, 1993 The existence and uniqueness in the class \(W^{2,p} \cap W_0^{1,p}\) of solutions of the elliptic equation \[ \sum^n_{i,j = 1} a_{ij} (x) {\partial^2u \over \partial x_i \partial x_j} + \sum^n_{i = 1} b_i(x) {\partial u \over \partial x} + e(x)u = f, \] assuming that the coefficients \(a_{ij}\) are in the Sarason's space VMO and the lower order terms ...

Dual native G‐quadruplex folding is associated with chromatin looping at the MYC locus
FEBS Open Bio, EarlyView.BG4‐detectable G‐quadruplex (G4) in HaCaT and NHEK keratinocytes identified folded and unfolded G4s enriched at promoters/TSSs and active enhancers, whereas unfolded G4s also overlapped weak/poised enhancers. At MYC–PVT1, 3C‐qPCR detected enhancer–promoter looping only when G4s were simultaneously folded at both regulatory elements under native ...

Chern classes for coherent sheaves [PDF]
We present in this paper a construction of Chern classes for a coherent sheaf S on a complex manifold X. In fact we construct classes Cp(S) in H2p(X, C), depending only on the smooth equivalence class of the sheaf S. and analytic classes CAp(S) in Hp(

Heterotropic regulation and negative homotropic cooperativity
FEBS Open Bio, EarlyView.We identified a structural module common to some proteins that couple negative cooperativity with heterotropic regulation, two features that rarely coexist. These proteins are ring‐like and present an ordered asymmetry whereby noncontacting subunits are symmetric, and their tertiary structure differs from that of contacting subunits.
