Vps Factors Are Required for Efficient Transcription Elongation in Budding Yeast [PDF]
Abstract There is increasing evidence that certain Vacuolar protein sorting (Vps) proteins, factors that mediate vesicular protein trafficking, have additional roles in regulating transcription factors at the endosome. We found that yeast mutants lacking the phosphatidylinositol 3-phosphate [PI(3)P] kinase Vps34 or its associated protein

ABSTRACT Chitosan, a polysaccharide upcycled from biowaste, has long promised sustainable, biocompatible, and antimicrobial films and devices, an appeal reinforced by its recent regulatory recognition, with several chitosan‐based antibacterial dressings gaining clearance through the Food and Drug Administration's 510(k) pathway.

The HY5-PIF regulatory module coordinates light and temperature control of photosynthetic gene transcription [PDF]
The ability to interpret daily and seasonal alterations in light and temperature signals is essential for plant survival. This is particularly important during seedling establishment when the phytochrome photoreceptors activate photosynthetic pigment ...

Productive transcription of the integrated HIV-1 provirus is restricted by cellular factors that inhibit RNA polymerase II elongation. The viral Tat protein overcomes this by recruiting a general elongation factor, P-TEFb, to the TAR RNA element that ...

The transcription elongation factor TCEA3 promotes the activity of the myogenic regulatory factors
The transcription elongation factor TFIIS is encoded by a three member gene family in vertebrates. Here we show that one member of this family, TCEA3, is upregulated during skeletal muscle differentiation and acts to promote gene activation by the myogenic regulatory family of transcription factors, which includes MyoD and myogenin.

The splicing factor SC35 has an active role in transcriptional elongation [PDF]
Mounting evidence suggests that transcription and RNA processing are intimately coupled in vivo, although each process can occur independently in vitro. It is generally thought that polymerase II (Pol II) C-terminal domain (CTD) kinases are recruited near the transcription start site to overcome initial Pol II pausing events, and that stably bound ...

Aberrant glycosylation in the glioblastoma tumor microenvironment drives therapeutic resistance. Here, a 3D bioprinted model was engineered by incorporating α‐NeuNAc‐(2→3)‐β‐D‐Gal‐ and chondroitin sulfate. Combined multiplex immunofluorescence and synchrotron‐based nanoCT analysis revealed that glycan‐matrix interactions dictate specific drug‐escape ...

Identification of autophosphorylation sites in eukaryotic elongation factor-2 kinase [PDF]
eEF2K [eEF2 (eukaryotic elongation factor 2) kinase] phosphorylates and inactivates the translation elongation factor eEF2. eEF2K is not a member of the main eukaryotic protein kinase superfamily, but instead belongs to a small group of so-called ...

Background Splicing factors are vital for the regulation of RNA splicing, but some have also been implicated in regulating transcription. The underlying molecular mechanisms of their involvement in transcriptional processes remain poorly understood ...
