High-Mobility-Group protein I can modulate binding of transcription factors to the U5 region of the human immunodeficiency virus Type 1 proviral promoter [PDF]

open access: yes, 2000
HMG I/Y appears to be a multifunctional protein that relies on in its ability to interact with DNA in a structure-specific manner and with DNA, binding transcriptional activators via distinct protein-protein interaction surfaces.

Human mid-gestation amniotic fluid contains interleukin-16 bioactivity [PDF]

open access: yes, 2009
CD4-positive cells are detectable in the human fetal gastrointestinal tract from 11 weeks of gestation. Interleukin-16 (IL-16) is a chemoattractant for CD4(+) cells and, via fetal swallowing of amniotic fluid, could mediate the influx of CD4(+) cells ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

The hepatitis B virus X protein activates nuclear factor of activated T cells (NF-AT) by a cyclosporin A-sensitive pathway. [PDF]

open access: yes, 1998
The X gene product of the human hepatitis B virus (HBx) is a transcriptional activator of various viral and cellular genes. We recently have determined that the production of tumor necrosis factor-alpha (TNF-alpha) by HBV-infected hepatocytes is ...

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

open access: yesFEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

open access: yesFEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

open access: yesFEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

The cold-inducible RNA-binding motif protein 3 (RBM3) prevents cell death through various mechanisms [PDF]

open access: yes, 2016
Moderate hypothermia promotes the survival of neural cells in a wide range of brain disorders. During hypothermia, a subgroup of proteins including two homologues, RNA-binding motif protein 3 (RBM3) and cold-inducible RNA-binding protein (CIRP), is ...

Evaluation of serum IL 18 / IL 18 binding protein ratio and their relation with IL- 18 gene polymorphisms in sample of Iraqi type 2 diabetes mellitus patients. A case control study

open access: yesJournal of the Pakistan Medical Association
Objectives: To evaluate the ratio of interleukin18 and interleukin18 binding protein in type 2 diabetes mellitus patients, and its relation with the presence of interleukin18-607C/A and interleukin18-137G/C gene polymorphisms and the type of ...

Activation of caspase-1 dependent interleukins in developmental brain trauma

open access: yesNeurobiology of Disease, 2007
Focal mechanical cortical trauma triggers diffuse apoptotic neurodegeneration in the developing rat brain which is associated with invasion of brain tissue with inflammatory mediators.
