Copia is a retrotransposon that appears to be distributed widely among the Drosophilidae subfamily. Evolutionary analyses of regulatory regions have indicated that the Copia retrotransposon evolved through both positive and purifying select...
The influence of historical geneflow, bathymetry and distribution patterns on the population genetics of morphologically diverse Galápagos' Opuntia echios [0.03%]
历史基因流、水深和分布模式对形态多样化的加拉帕戈斯Opuntia echios种群遗传学的影响

Throughout history, remote archipelagos have repeatedly been designated natural laboratories to study evolutionary processes. The extensive, geographically structured, morphological variation within Galápagos' Opuntia cacti has been presum...
Evolution of metamorphism in thymidylate synthases within the primate lineages [0.03%]
灵长类谱系中胸苷酸合成酶的进化及变构效应的发展变迁研究

BeiBei Luo et al.
Crystal structures of human thymidylate synthase (hTS) revealed that the protein exists in active and inactive conformations, defined by the position of a loop containing the active site nucleophile. TS is highly homologous among diverse sp...
Polymorphisms in the extracellular region of dopamine receptor D4 within and among avian orders [0.03%]

Polymorphisms in the dopamine receptor D4 gene (DRD4) have been widely investigated to assess their correlation with variations in animal behavior. We precisely examined polymorphisms in the extracellular region of DRD4 in 75 avian species ...
Identification and characterization of gene expression involved in the coloration of cichlid fish using microarray and qRT-PCR approaches [0.03%]
微阵列和实时定量逆转录 PCR 用于识别及表征丽鱼科鱼类色泽相关基因表达

The ubiquitous distribution, homology over three domains, and key role in the membrane formation of the enzymes of the CDP-alcohol phosphatidyltransferase family, as well as phylogenetic analyses of lipid synthesizing enzymes suggest that t...
The non-LTR retrotransposon R2 in termites (Insecta, Isoptera): characterization and dynamics [0.03%]
螱菌中非LTR端粒重复序列R2的特征及其动态变化规律(Insecta, Isoptera)
Silvia Ghesini,Andrea Luchetti,Mario Marini et al.
Silvia Ghesini et al.
The full-length element of the non-LTR retrotransposon R2 is here characterized in three European isopteran species: the more primitive Kalotermes flavicollis (Kalotermitidae), including two highly divergent mitochondrial lineages, and the ...
Monomer abundance distribution patterns as a universal biosignature: examples from terrestrial and digital life [0.03%]
单体丰度分布模式作为通用生物标志物的例子：来自地球和数字生命的形式

Organisms leave a distinctive chemical signature in their environment because they synthesize those molecules that maximize their fitness. As a result, the relative concentrations of related chemical monomers in life-bearing environmental s...
Isolation and characterization of the CYP2D6 gene in Felidae with comparison to other mammals [0.03%]
猫科动物CYP2D6基因的分离与鉴定及其与其他哺乳动物的比较
Tamara Schenekar,Kathrin A Winkler,Jennifer L Troyer et al.
Tamara Schenekar et al.
The highly polymorphic CYP2D6 protein metabolizes about 25% of commonly used drugs and underlies a broad spectrum of drug responses among individuals. In contrast to extensive knowledge on the human CYP2D6 gene, little is known about the ge...

We have recently shown that homologs of mammalian hair keratins are expressed in the claws of the green anole lizard, Anolis carolinensis. To test whether reptilian hair keratin homologs are functionally associated with claws, we investigat...
