A threonyl-tRNA synthetase-like protein has tRNA aminoacylation and editing activities

TARS and TARS2 encode cytoplasmic and mitochondrial threonyl-tRNA synthetases (ThrRSs) in mammals, respectively. Interestingly, in higher eukaryotes, a third gene, TARSL2, encodes a ThrRS-like protein (ThrRS-L), which is highly homologous to cytoplasmic ThrRS but with a different N-terminal extension (N-extension). Whether ThrRS-L has canonical functions is unknown. In this work...

Up-regulated microRNA-299 corrected with poor prognosis of glioblastoma multiforme patients by targeting ELL2

An increasing understanding of the genes and molecular pathways of glioblastoma multiforme (GBM) can provide us a useful insight for the development of more effective targeted therapeutic.

Translational fidelity maintenance preventing Ser mis-incorporation at Thr codon in protein from eukaryote

Aminoacyl-tRNA synthetase (aaRS) catalyzes the first step of protein synthesis, producing aminoacyl-tRNAs as building blocks. Eukaryotic aaRS differs from its prokaryotic counterpart in terminal extension or insertion. Moreover, the editing function of aaRSs is an indispensable checkpoint excluding non-cognate amino acids at a given codon and ensuring overall translational...

The GH18 family of chitinases: Their domain architectures, functions and evolutions

The glycoside hydrolase 18 (GH18) family of chitinases is a multigene family that plays various roles, such as ecdysis, embryonic development, allergic inflammation and so on. Efforts are still needed to reveal their functional diversification in an evolutionary and systematic manner. We collected 85 GH18 genes from eukaryotic representatives. The domain architectures of GH18...

Initial Stages of Tumor Cell-Induced Angiogenesis: Evaluation Via Skin Window Chambers in Rodent Models

BACKGROUND: There is a paucity of information about events that follow immediately after tumor cells are triggered to initiate the process of angiogenesis (the formation of new blood vessels). Such information is relevant to the issue of when micrometastases vascularize and has implications for the accessibility of micrometastases to various treatments. In this study, we...
