S100 Proteins—Intracellular and Extracellular Function in Norm and Pathology

Biomolecules
The S100 proteins are small, ubiquitous, mostly homodimeric proteins containing two EF-hand structures, that is, helix-loop-helix motifs specialized in high-affinity calcium-binding (~10−6 M) [...]

Analysis of bHLH genes from foxtail millet (Setaria italica) and their potential relevance to drought stress.

PLoS ONE, 2018
Foxtail millet is very a drought-tolerant crop. Basic helix-loop-helix (bHLH) transcription factors are involved in many drought-stress responses, but foxtail millet bHLH genes have been scarcely examined. We identified 149 foxtail millet bHLH genes in a

Genome-wide analysis of basic helix–loop–helix superfamily members related to anthocyanin biosynthesis in eggplant (Solanum melongena L.) [PDF]

PeerJ, 2019
The basic helix–loop–helix (bHLH) superfamily is considered the second largest transcription factor (TF) family. It plays regulatory roles in the developmental processes of plants and in their defense responses.

Hybrids of the bHLH and bZIP protein motifs display different DNA-binding activities in vivo vs. in vitro.

PLoS ONE, 2008
Minimalist hybrids comprising the DNA-binding domain of bHLH/PAS (basic-helix-loop-helix/Per-Arnt-Sim) protein Arnt fused to the leucine zipper (LZ) dimerization domain from bZIP (basic region-leucine zipper) protein C/EBP were designed to bind the E-box

E box motifs as mediators of proviral latency of human retroviruses

Retrovirology, 2009
The palindromic sequence motifs (CANNTG) known as E boxes are considered as binding sites for the basic helix-loop-helix (bHLH) class of DNA-binding proteins.

SlCESTA Is a Brassinosteroid-Regulated bHLH Transcription Factor of Tomato That Promotes Chilling Tolerance and Fruit Growth When Over-Expressed

Frontiers in Plant Science, 2022
Brassinosteroids (BRs) are required for various aspects of plant growth and development, but also participate in stress responses. The hormones convey their activity through transcriptional regulation and posttranslational modification of transcription ...

Conserved Structural Motifs at the C-Terminus of Baculovirus Protein IE0 are Important for its Functions in Transactivation and Supporting hr5-mediated DNA Replication

Viruses, 2012
IE0 and IE1 are transactivator proteins of the most studied baculovirus, the <em>Autographa californica</em> multiple nucleopolyhedrovirus (AcMNPV). IE0 is a 72.6 kDa protein identical to IE1 with the exception of its 54 N-terminal amino acid

ETS-Mediated Cooperation between Basic Helix-Loop-Helix Motifs of the Immunoglobulin μ Heavy-Chain Gene Enhancer [PDF]

Molecular and Cellular Biology, 1998
The muE motifs of the immunoglobulin mu heavy-chain gene enhancer bind ubiquitously expressed proteins of the basic helix-loop-helix (bHLH) family. These elements work together with other, more tissue-restricted elements to produce B-cell-specific enhancer activity by presently undefined combinatorial mechanisms.

bHLH transcription factor family identification, phylogeny, and its response to abiotic stress in Chenopodium quinoa

Frontiers in Plant Science, 2023
The second-largest transcription factor superfamily in plants is that of the basic helix-loop-helix (bHLH) family, which plays an important complex physiological role in plant growth, tissue development, and environmental adaptation.

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.
