binding capacity,   etc   ; RNA; mammals; temperature;     Show all 4 Subjects
Abstract:
... How plants sense temperature is an important question. Here, we highlight recent achievements in identifying plant thermosensors, including RNA switch and protein–DNA binding ability. Finally, we borrow an idea from one recent mammalian study and propose a putative temperature-sensitive kinase as a thermosensory mechanism. ...

Abstract:
... We investigated the physicochemical and functional properties of rice flour modified by partial protein hydrolysis and the further effects of pH. Protease treatment changed the molecular composition, surface hydrophobicity, and protein solubility, thereby altering the surface charge, water absorption capacity, and solubility of rice flour. The pasting viscosity of rice flour at neutral or basic pH ...

Abstract:
... Alternative splicing (AS) is a key process to expand the diversity of mRNA and protein from the genome and it is crucial for fate determination of embryonic stem cells (ESCs) by encoding isoforms with different functions to regulate the balance between pluripotency maintenance and differentiation. Since the role of the Hippo pathway in ESCs is controversial, there may be novel isoforms of Taz, a k ...

Our understanding of the mechanisms governing aptamer-ligand recognition and binding is however lagging, stymieing the progress in the rational design of new aptamers and optimization of the known ones. Here we demonstrate the capab ...
