Lysozymes are membrane-bound organelles that occur in the cytoplasm of animal cells. These organelles contain an array of hydrolytic enzymes required for the degradation of various macromolecules. There are two types of lysozymes: Primary lysozymecontaining hydrolytic enzymes like lipases, amylases, pro...

We found that, although the presence of the second stalk subunit is conserved throughout the eukaryotic tree of life for Pol II, in the case of Pol I, it is found only in some species from a division of fungi, ascomycota (Extended Data Fig. 3a). Consequently, previous studies using S....
For example, hyphae in some Basidiomycota are heterokaryotic and become dikaryotic only in the cells basal to the basidium. Basidiospores are sometimes binucleate and germinate directly to form the dikaryotic stage (Raper, 1978). Occasionally, the homokaryon is self-fertile and clamp connections...
elegans, we found that pix-1 is required for the assembly of integrin adhesion complexes (IACs) at borders between muscle cells, and is required for locomotion of the animal. A pix-1 null mutant has a reduced level of activated Rac in muscle. PIX-1 localizes to IACs at muscle cell ...
Guanine-rich sequences are able to form complex RNA structures termed RNA G-quadruplexes in vitro. Because of their high stability, RNA G-quadruplexes are proposed to exist in vivo and are suggested to be associated with important biological relevance. H
Functions of C-type lectins in signalling Many C-type lectins found on cells in the immune system have been reported to initiate intracellular signalling, but this remains the least well understood function of these receptors. The different arrangements of these receptors in the plasma membrane refle...
However, these enzymes show high specificity to their target sugar units, which consequently results in only a limited number of carbohydrates in the feed that can be digested by the animal [2]. Non-digestible carbohydrates that reach the large intestine may be digested by microbial enzymes ...
mucous suspension, spinal fluid, and amniotic fluid. These extracellular DNA molecules are found in humans and both the animal and plant kingdoms. In addition, extracellular DNA molecules are found and released in cell culture supernatants either from cell lines, primary cells, organoids, or embryo...
