Repeat proteins challenge the concept of structural domains
(Portland Press, 2015-10)
Structural domains are believed to be modules within proteins that can fold and function independently. Some proteins show tandem repetitions of apparent modular structure that do not fold independently, but rather co-operate ...
The Design of Repeat Proteins: Stability Conflicts with Functionality
(Insight Medical Publishing, 2017-03)
Repeat proteins are constituted by a variable number of copies of a given structural element that is tandemly repeated along a longitudinal axis. They mainly function as protein-protein interactors with binding interfaces ...
Phenotypic and genetic parameters compared during repeated measures of longissimus muscle area and subcutaneous fat thickness in Nelore cattle
(Funpec-editora, 2011-01-01)
Real-time ultrasound is currently used for in vivo carcass evaluation of beef cattle. We estimated heritability and repeatability coefficients for ultrasound-measured carcass traits in Nelore cattle. We measured longissimus ...
Comparative analysis of tandem repeats from hundreds of species reveals unique insights into centromere evolution
(Biomed Central Ltd., 2013-01-01)
Background: Centromeres are essential for chromosome segregation, yet their DNA sequences evolve rapidly. In most animals and plants that have been studied, centromeres contain megabase-scale arrays of tandem repeats. ...
Shorter CAG repeat in the AR gene is associated with atypical hyperplasia and breast carcinoma
(2007-03-01)
Background: Previous reports into the role of [CAG]n repeat lengths in the androgen receptor (AR) gene indicate that these may play an important part in the development and progression of breast cancer, however, knowledge ...
Repeated-batch fermentation of sugarcane bagasse hemicellulosic hydrolysate to ethanol using two xylose-fermenting yeasts
(2022-01-01)
In this study, a repeated-batch fermentation of hemicellulosic sugarcane bagasse hydrolysate was investigated to produce bioethanol using two xylose-fermenting yeasts, Scheffersomyces stipitis and Scheffersomyces shehatae. ...
Repeatability in the contact calling system of Spix's disc-winged bat (Thyroptera tricolor)
(2015-01)
Spix's disc-winged bat (Thyroptera tricolor) forms cohesive groups despite using an extremely ephemeral roost, partly due to the use of two acoustic signals that help individuals locate roost sites and group embers. While ...
Unusually short tandem repeats appear to reach chromosome ends of Rhynchosciara americana (Diptera: Sciaridae)
(SPRINGER, 2010)
The characterisation of sequences at chromosome ends of Rhynchosciara americana was continued with the screening of a genomic library using as a probe a short repeat identified in a previous report (M-22, 22 bp) which was ...
Cloning and characterisation of a novel chromosome end repeat enriched with homopolymeric (dA)/(dT) DNA in Rhynchosciara americana (Diptera: Sciaridae)
(SPRINGERDORDRECHT, 2012)
Short tandem DNA repeats and telomerase compose the telomere structure in the vast majority of eukaryotic organisms. However, such a conserved organisation has not been found in dipterans. While telomeric DNA in Drosophila ...
