Platypus globin genes and flanking loci suggest a new insertional model for beta-globin evolution in birds and mammals

open access: yesBMC Biology, 2008
Background Vertebrate alpha (α)- and beta (β)-globin gene families exemplify the way in which genomes evolve to produce functional complexity. From tandem duplication of a single globin locus, the α- and β-globin clusters expanded, and then were ...

Creating New β-Globin-Expressing Lentiviral Vectors by High-Resolution Mapping of Locus Control Region Enhancer Sequences. [PDF]

open access: yes, 2020
Hematopoietic stem cell gene therapy is a promising approach for treating disorders of the hematopoietic system. Identifying combinations of cis-regulatory elements that do not impede packaging or transduction efficiency when included in lentiviral ...

Krüppel-Like Transcription Factor KLF1 Is Required for Optimal γ- and β-Globin Expression in Human Fetal Erythroblasts. [PDF]

open access: yesPLoS ONE, 2016
In human adult erythroid cells, lower than normal levels of Krüppel-like transcription factor 1 (KLF1) are generally associated with decreased adult β- and increased fetal γ-globin gene expression. KLF1 also regulates BCL11A, a known repressor of adult γ-

Visible Volume: a Robust Measure for Protein Structure Characterization [PDF]

open access: yes, 1997
We propose a new characterization of protein structure based on the natural tetrahedral geometry of the β carbon and a new geometric measure of structural similarity, called visible volume.

Minor Loops in Major Folds: Enhancer-Promoter Looping, Chromatin Restructuring, and Their Association with Transcriptional Regulation and Disease. [PDF]

open access: yes, 2015
The organization and folding of chromatin within the nucleus can determine the outcome of gene expression. Recent technological advancements have enabled us to study chromatin interactions in a genome-wide manner at high resolution.

Imbalanced globin chain synthesis determines erythroid cell pathology in thalassemic mice

open access: yesHaematologica, 2009
Background β-thalassemia occurs from the imbalanced globin chain synthesis due to the absence or inadequate β-globin chain production. The excessive unbound α-globin chains precipitate in erythroid precursors and mature red blood cells leading to ...

Reactivation of a developmentally silenced embryonic globin gene

open access: yesNature Communications, 2021
Globin loci harbor genes that are expressed embryonically and silenced postnatally. Here the authors show that zeta-globin silencing depends upon selective hypoacetylation of its TAD subdomain, which blocks its interaction with the alpha-globin super ...

Structural interpretation of the amino acid sequence of a second domain from the Artemia covalent polymer globin [PDF]

open access: yes, 1990
Artemia has a complex extracellular hemoglobin of Mr 260,000 comprising two globin chains (Mr 130,000) each of which is a polymer of eight covalently linked domains of Mr 16,000.

Decreased cold‐sensing function of the transient receptor potential channel TRPM8 from tailed amphibians

open access: yesFEBS Open Bio, EarlyView.
Despite frogs avoiding low temperatures, examination of four salamander species revealed that none avoided cold and all possessed cold tolerance. Functional analysis of TRPM8, a cold sensor, showed that all salamander TRPM8s had lost their cold sensitivity.

The role of WDR5 in silencing human fetal globin gene expression

open access: yesHaematologica, 2012
Background Histone H3 lysine 4 (K4) methylation has been linked with transcriptional activity in mammalian cells. The WD40-repeat protein, WDR5, is an essential component of the MLL complex that induces histone H3 K4 methylation, but the role of WDR5 in ...
