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 complete mitochondrial genome of Batocera rubus Linnaeus, 1785 (Coleoptera: Cerambycidae)

open access: yesMitochondrial DNA. Part B. Resources, 2023
Batocera rubus severely impacts on the health of banyan trees. In this study, the whole mitochondrial genome for B. rubus was found to be 16,158 bp with a GC content of 23.9%, including 39.1% A, 37.0% T, 14.8% C, and 9.1% G.

Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function

open access: yesFEBS Open Bio, EarlyView.
We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...

Phylogenetic relationships of Cryptosporidium parasites based on the 70- kilodalton heat shock protein (HSP70) gene [PDF]

open access: yes, 2000
We have characterized the nucleotide sequences of the 70-kDa heat shock protein (HSP70) genes of Cryptosporidium baileyi, C. felis, C. meleagridis, C. muris, C. serpentis, C. wrairi, and C. parvum from various animals.

Novel single nucleotide polymorphism-based assay for genotyping Mycobacterium avium subsp. paratuberculosis [PDF]

open access: yes, 2016
Typing of Mycobacterium avium subspecies paratuberculosis strains presents a challenge, since they are genetically monomorphic and traditional molecular techniques have limited discriminatory power.

Molecular dynamics simulations of positively selected codons in FcγRI reveal novel biochemical binding properties

open access: yesFEBS Open Bio, EarlyView.
Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...

Molecular Identification and Phylogenetic Analysis of Multidrug-resistant Bacteria using 16S rDNA Sequencing

open access: yesJournal of Pure and Applied Microbiology, 2018
In the present study, 30 multidrug-resistant bacterial samples were isolated from different hospitals in the Taif governorate in Saudi Arabia. Given its discriminating power as a universal phylogenetic marker, the 16S rDNA gene was sequenced in a ...

On the analysis of phylogenetically paired designs [PDF]

open access: yesEcology and Evolution, 2015
AbstractAs phylogenetically controlled experimental designs become increasingly common in ecology, the need arises for a standardized statistical treatment of these datasets. Phylogenetically paired designs circumvent the need for resolved phylogenies and have been used to compare species groups, particularly in the areas of invasion biology and ...

Small RNA pathways in mammalian oocytes

open access: yesFEBS Open Bio, EarlyView.
Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...
