The globins are well-known proteins, and in vertebrates there are two types: haemoglobin and myoglobin. Now a third has been identified, in both mice and humans, that occurs in the nervous system, especially the brain. Like the other globins its main function is probably facilitating oxygen supply.

The Globins of Campylobacter jejuni
2013Campylobacter jejuni is a zoonotic Gram-negative bacterial pathogen that is exposed to reactive nitrogen species, such as nitric oxide, from a variety of sources. To combat the toxic effects of this nitrosative stress, C. jejuni upregulates a small regulon under the control of the transcriptional activator NssR, which positively regulates the ...

Molecular weight determinations on the α-globin and β-globin mRNAs
Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1976The globin mRNAs containing between 30 and 40 polyadenylate residues can be separated from thos mRNAs containing longer poly(A) regions by Millipore filter binding. The molecular weights of the alpha-and beta-globin mRNAs containing this size class of poly(A) have beed determined by lectrophoresis on 3.7% polyacrylamide gels in the presence of 99 ...

To the Editor:— In recent literature globin insulin has been erroneously referred to as a histone insulin. While there is some similarity between globin and the histones, the differences are so obvious that it is necessary to distinguish between them.

The Globins of Cyanobacteria and Algae
2013Approximately, 20 years ago, a haemoglobin gene was identified within the genome of the cyanobacterium Nostoc commune. Haemoglobins have now been confirmed in multiple species of photosynthetic microbes beyond N. commune, and the diversity of these proteins has recently come under increased scrutiny.

A bioinformatics survey of about 120 protist and 240 fungal genomes and transcriptomes revealed a broad array of globins, representing five of the eight subfamilies identified in bacteria. Most conspicuous is the absence of protoglobins and globin-coupled sensors, except for a two-domain globin in Leishmanias, that comprises a nucleotidyl cyclase ...

Activation of the δ-Globin Gene by the β-Globin Gene CACCC Motif
Blood Cells, Molecules, and Diseases, 1999The promoter region of adult beta globin genes in humans and other mammals contains conserved regions of pivotal importance for their regulated tissue specific expression. These include the CACCC and CAAT motifs. The CACCC motif is duplicated in humans and other mammals.

Increase in globin chains and globin mRNA in erythroleukemia cells in response to hemin
Archives of Biochemistry and Biophysics, 1977Abstract Addition of 50 μ m hemin to mouse erythroleukemia cells cultured in 0.5% dimethyl-sulfoxide (DMSO) resulted in >10-fold stimulation of globin chain synthesis as a percentage of acid precipitable protein. In cultures fully induced with 1.5% DMSO, addition of 15 m m 3-amino-1,2,4-triazole (AT), an inhibitor of heme synthesis, reduced globin ...

Nutritive Value of Globin-Amino Acid and Complementary Globin-Cereal Mixtures
The Journal of Nutrition, 1980Protein efficiency ratios (PER) were determined using male weanling rats fed diets containing bovine globin alone and with wheat and corn gluten. Simultaneous equations and graphical methods were devised for selecting combinations of globin and cereal proteins to provide optimal and suboptimal profiles of limiting amino acids.

Ratios of α-to β-globin mRNA and regulation of globin synthesis in reticulocytes
Nature, 1977THE genomes of several mammalian species contain at least two α globin loci and a single β globin locus so that the ratio of α- to β-globin genes is 2 : 1 or more1–3. Despite this difference in number of genes, reticulocytes from these species synthesise equal numbers of α- and β-globin chains indicating that compensatory regulation must occur ...
