Conservation of the TRAPPII-specific subunits of a Ypt/Rab exchanger complex

open access: yesBMC Evolutionary Biology, 2007
Background Ypt/Rab GTPases and their GEF activators regulate intra-cellular trafficking in all eukaryotic cells. In S. cerivisiae, the modular TRAPP complex acts as a GEF for the Golgi gatekeepers: Ypt1 and the functional pair Ypt31/32.

Cis- and Trans-Activation of Hormone Receptors: the LH Receptor [PDF]

open access: yesMolecular Endocrinology, 2002
AbstractG protein-coupled receptors (GPCRs) accommodate a wide spectrum of activators from ions to glycoprotein hormones. The mechanism of activation for this large and clinically important family of receptors is poorly understood. Although initially thought to function as monomers, there is a growing body of evidence that GPCR dimers form, and in some

Trans-activation of heparanase promoter by ETS transcription factors [PDF]

open access: yesOncogene, 2003
The remodeling of extracellular matrix (ECM) is an important process required for cancer cells to turn into invasive and metastatic cancer cells. To dissolve the protein components of ECM, matrix metalloproteinases are some of the essential enzymes. Another ECM remodeling enzyme is the heparanase (Hpa) that digests the heparin sulfate component of the ...

Harnessing noncanonical trans-cleavage characteristics of Cas12 and Cas13a to enhance CRISPR-based diagnostics

open access: yesCommunications Biology
Cas12 and Cas13 are extensively utilized in molecular diagnostics for their trans-cleavage activities, yet their activation characteristics remain partially understood. Here, we conduct an in-depth investigation of Cas12a, Cas12f1, and Cas13a, uncovering

Characterization of the transcriptional trans activator of human foamy retrovirus [PDF]

open access: yesJournal of Virology, 1991
The human foamy viruses, or spumaviruses, a distinct subfamily of complex human retroviruses, remain poorly understood both in terms of their pathogenic potential and in terms of the regulatory mechanisms that govern their replication. Here, we demonstrate that the human spumaretrovirus shares with other complex human retroviruses the property of ...

Specific multivalent molecules boost CRISPR-mediated transcriptional activation

open access: yesNature Communications
CRISPR/Cas-based transcriptional activators can be enhanced by intrinsically disordered regions (IDRs). However, the underlying mechanisms are still debatable.

trans-Activation of a globin promoter in nonerythroid cells. [PDF]

open access: yesMolecular and Cellular Biology, 1991
We show that expression in fibroblasts of a single cDNA, encoding the erythroid DNA-binding protein Eryf1 (GF-1, NF-E1), very efficiently activates transcription of a chicken alpha-globin promoter, trans-Activation in these cells occurred when Eryf1 bound to a single site within a minimal globin promoter.
