Diverse functions of perineuronal nets.
Perineuronal nets represent well-organised components of the extracellular matrix, which are surrounding cell bodies, dendrites, and axon segments of a particular class of neurones as well as forming lattice-like structures. The role of perineuronal nets is not fully elucidated yet. Perineuronal nets may play a beneficial role by stabilizing the extracellular milieu assuring the characteristic ...
متن کاملProtein diverse functions and locations
organismal, ecological and evolutionary levels continue to develop rapidly. Increasingly, biologists need to confront organised complexity, of which living systems are the paramount example. Both spontaneous emergence of order and the maintenance of stability in complex systems in the face of highly variable environments need to be researched further. Complex structures are generated and mainta...
متن کاملFunctions for diverse metabolic activities in heterochromatin.
Growing evidence demonstrates that metabolism and chromatin dynamics are not separate processes but that they functionally intersect in many ways. For example, the lysine biosynthetic enzyme homocitrate synthase was recently shown to have unexpected functions in DNA damage repair, raising the question of whether other amino acid metabolic enzymes participate in chromatin regulation. Using an in...
متن کاملProtein monoubiquitylation: targets and diverse functions.
Ubiquitin is a 76-amino acid protein whose conjugation to protein targets is a form of post-translational modification. Protein ubiquitylation is characterized by the covalent attachment of the COOH-terminal carboxyl group of ubiquitin to an amino group of the substrate protein. Given that the NH2 -terminal amino group is usually masked, internal lysine residues are most often targeted for ubiq...
متن کاملDiverse Yet Efficient Retrieval using Hash Functions
Typical retrieval systems have three requirements: a) Accurate retrieval i.e., the method should have high precision, b) Diverse retrieval, i.e., the obtained set of points should be diverse, c) Retrieval time should be small. However, most of the existing methods address only one or two of the above mentioned requirements. In this work, we present a method based on randomized locality sensitiv...
