FEBS Open Bio, EarlyView.Amino acids sequence of two different proteins with the same sequence (chameleon sequence—black boxes) represent in 3D structure of the proteins different secondary structures: HHHH—helical and BBB—Beta‐structural. The chains folded in water environment adopt different III‐order structures in which the chameleon fragments appear to adopt similar status

, 1984 The ras genes, which were first identified by their presence in RNA tumor viruses and which belong to a highly conserved gene family in vertebrates, have 2 close homologues in yeast, detectable by Southern blotting. Both genes (RAS1 and RAS2) were cloned

Functional dissection of the "Drosophila melanogaster" fibroblast growth factor signalling pathway in branching morphogenesis of the developing tracheal system [PDF]
, 2004 Fibroblast Growth Factor (FGF) signalling is involved in numerous developmental processes ranging from cell determination to mitogenesis, and cell survival to cell migration.

Long‐term hippocampal alterations and cognitive impairment in a murine model of surgical sepsis
FEBS Open Bio, EarlyView.Using a mouse model of surgical sepsis, we tested long‐term memory and analyzed the transcriptome of single cells isolated from the hippocampus. Survivor mice showed worse memory, loss of certain brain cell subpopulations, and abnormal immune cell activity—suggesting that post‐sepsis brain alterations may be linked to cognitive deficits.

ARF: the most misunderstood GTPase I ever knew - why study ARF GAPs
Frontiers in Molecular BiosciencesADP-ribosylation factors (ARFs) are GTP-binding proteins that were discovered in the early 1980s, shortly after heterotrimeric GTP-binding proteins (G proteins) and nearly simultaneously with RAS.

Ras signaling enhances the activity of C/EBPalpha to induce granulocytic differentiation by phosphorylation of serine 248 [PDF]
, 2003 The transcription factor C/EBPa regulates early steps of normal granulocyte differentiation since mice with a disruption of the C/EBPa gene do not express detectable levels of the G-CSF receptor and produce no neutrophils.

An Experimentally Derived Database of Candidate Ras-Interacting Proteins
, 2007 We used a TAP-tag approach to identify candidate binding proteins for the related Ras family GTPases: H-Ras, R-Ras, and Rap1A. Protein complexes were isolated from mouse fibroblasts, and component proteins were identified by a combination of nanoflow ...

YIPFα1A expression is regulated by multilayered molecular mechanisms
FEBS Open Bio, EarlyView.YIPFα1A, a five‐pass Golgi protein, is regulated at multiple layers. (1) Rare‐codon enrichment drives translation‐coupled mRNA decay. (2) A proximal 3′‐UTR element stabilizes mRNA. (3) A distal 3′‐UTR element included by alternate poly(A) site usage represses translation, which can be overridden by the proximal 3′‐UTR element.

Optimizing photoactivation of PA‐mCherry for optical pooled CRISPR screens
FEBS Open Bio, EarlyView.Photoactivatable PA‐mCherry finds widespread use to optically tag individual cells. However, confocal 405 nm UV laser‐scanning (normal scan) is much less efficient than widefield UV illumination, limiting the use of PA‐mCherry on confocal instruments. We remedy this limitation by reporting that rapid and repeated confocal scanning with a low‐intensity,
