Protein chainmail variants in dsDNA viruses. [PDF]

open access: yes, 2015
First discovered in bacteriophage HK97, biological chainmail is a highly stable system formed by concatenated protein rings. Each subunit of the ring contains the HK97-like fold, which is characterized by its submarine-like shape with a 5-stranded β ...

Fluorescence Resonance Energy Transfer (FRET) as a method to calculate the dimerization strength of basic Helix-Loop-Helix (bHLH) proteins

open access: yesBiological Procedures Online, 2004
Post-translational modifications such as phosphorylation play a vital role in the regulation of protein function. In our study of the basic Helix-loop-Helix (bHLH) transcription factor HAND1, we show that HAND1 is phosphorylated during the trophoblast ...

Context dependence of proneural bHLH proteins [PDF]

open access: yes, 2008
A key point of neural development is the commitment of progenitor cells to a specific neural fate. In all animals studied, proneural proteins — transcription factors of the basic helix-loop-helix (bHLH) family — are central to this process.

Rap1 binding and a lipid-dependent helix in talin F1 domain promote integrin activation in tandem. [PDF]

open access: yes, 2019
Rap1 GTPases bind effectors, such as RIAM, to enable talin1 to induce integrin activation. In addition, Rap1 binds directly to the talin1 F0 domain (F0); however, this interaction makes a limited contribution to integrin activation in CHO cells or ...

An exploration of alternative visualisations of the basic helix-loop-helix protein interaction network [PDF]

open access: yesBMC Bioinformatics, 2007
Abstract Background Alternative representations of biochemical networks emphasise different aspects of the data and contribute to the understanding of complex biological systems. In this study we present a variety of automated methods for visualisation of a protein-protein interaction network, using the basic helix ...

Diversification of DNA binding specificities enabled SREBP transcription regulators to expand the repertoire of cellular functions that they govern in fungi.

open access: yesPLoS Genetics, 2018
The Sterol Regulatory Element Binding Proteins (SREBPs) are basic-helix-loop-helix transcription regulators that control the expression of sterol biosynthesis genes in higher eukaryotes and some fungi.

Differential Interactions of Id Proteins with Basic-Helix-Loop-Helix Transcription Factors [PDF]

open access: yesJournal of Biological Chemistry, 1997
Dimerization of three Id proteins (Id1, Id2, and Id3) with the four class A E proteins (E12, E47, E2-2, and HEB) and two groups of class B proteins, the myogenic regulatory factors (MRFs: MyoD, myogenin, Myf-5 and MRF4/Myf-6), and the hematopoietic factors (Scl/Tal-1, Tal-2, and Lyl-1) were tested in a quantitative yeast 2-hybrid assay.

Regulation of protein function by interfering protein species

open access: yesBiomolecular Concepts, 2012
Most proteins do not function alone but act in protein complexes. For several transcriptional regulators, it is known that they have to homo- or heterodimerize prior to DNA binding.

Anti-tumor effects of an ID antagonist with no observed acquired resistance

open access: yesnpj Breast Cancer, 2021
ID proteins are helix-loop-helix (HLH) transcriptional regulators frequently overexpressed in cancer. ID proteins inhibit basic-HLH transcription factors often blocking differentiation and sustaining proliferation.

Transcriptome Analysis of Lolium temulentum Exposed to a Combination of Drought and Heat Stress

open access: yesPlants, 2021
Drought and heat are two major stresses predicted to increase in the future due to climate change. Plants exposed to multiple stressors elicit unique responses from those observed under individual stresses.
