Effect of vitamin K depletion and restoration on sphingolipid metabolism in Bacteroides melaninogenicus

open access: yesJournal of Lipid Research, 1972
Bacteroides melaninogenicus requires vitamin K for normal growth. Cells incubated in a vitamin K-free medium form defective cell envelopes. Studies with vitamin K-grown “K(+)” and vitamin K-depleted “K(–)” cells showed that [14C]choline and [14C]glycerol

Vaspin identified as a DNA‐binding serpin with functional consequences for protease inhibition

open access: yesThe FEBS Journal, EarlyView.
Vaspin is a serpin that is expressed in skin, adipose tissue, and liver. It binds to single‐ and double‐stranded DNA with high affinity. This binding is unaffected by mutation of the known heparin‐binding site, accelerates the inhibition of the inflammatory protease KLK7, and may contribute to vaspin's nuclear localization.

Identification of an N-terminal glycogen synthase kinase 3 phosphorylation site which regulates the functional localisation of polycystin-2 in vivo and in vitro [PDF]

open access: yes, 2006
PKD2 is mutated in 15% of patients with autosomal dominant polycystic kidney disease (ADPKD). Polycystin-2 (PC2), the PKD2 protein, is a nonselective Ca2 + -permeable cation channel which may function at the cell surface and ER. Nevertheless, the factors

Inference via the Skewness‐Kurtosis Set

open access: yesInternational Statistical Review, EarlyView.
Summary Kurtosis minus squared skewness is bounded from below by 1, but for unimodal distributions, this parameter is bounded by 189/125. In some applications, it is natural to compare distributions by comparing their kurtosis‐minus‐squared‐skewness parameters. The asymptotic behavior of the empirical version of this parameter is studied here for i.i.d.

Protein kinase-mediated phosphorylation of a purified sterol ester hydrolase from bovine adrenal cortex.

open access: yesJournal of Lipid Research, 1978
Sterol ester hydrolase (cholesterol esterase, E.C. 3.1.1.13) of bovine adrenal cortex has been extensively purified by ammonium sulfate fractionation, acid precipitation, hydroxylapatite chromatography, and Sephadex G-200 chromatography.

Impact of PNKP mutations associated with microcephaly, seizures and developmental delay on enzyme activity and DNA strand break repair [PDF]

open access: yes, 2012
Microcephaly with early-onset, intractable seizures and developmental delay (MCSZ) is a hereditary disease caused by mutations in polynucleotide kinase/phosphatase (PNKP), a DNA strand break repair protein with DNA 5'-kinase and DNA 3'-phosphatase ...

A signaling pathway mediating abscisic acid‐induced jasmonic acid biosynthesis during strawberry ripening

open access: yesJournal of Integrative Plant Biology, EarlyView.
During strawberry ripening, abscisic acid signaling activates SnRK2.6, which phosphorylates and degrades the JAZ12 repressor. This releases the MYC2 transcription factor, directly activating jasmonic acid biosynthesis genes. The resulting jasmonic acid accumulation drives aroma production, thereby coupling ripening with scent formation through this ...
