Human PCNA Structure, Function and Interactions [PDF]
Biomolecules, 2020 Proliferating cell nuclear antigen (PCNA) is an essential factor in DNA replication and repair. It forms a homotrimeric ring that embraces the DNA and slides along it, anchoring DNA polymerases and other DNA editing enzymes. It also interacts with regulatory proteins through a sequence motif known as PCNA Interacting Protein box (PIP-box).

Integrin Structure, Activation, and Interactions [PDF]
Cold Spring Harbor Perspectives in Biology, 2011 Integrins are large, membrane-spanning, heterodimeric proteins that are essential for a metazoan existence. All members of the integrin family adopt a shape that resembles a large "head" on two "legs," with the head containing the sites for ligand binding and subunit association.

Structures and interactions of syndecans [PDF]
The FEBS Journal, 2019 The four syndecans identified in mammals are membrane proteoglycans that play major roles in regulating cell behavior, cell signaling, and cell‐matrix interactions. The membrane forms of these syndecans function as receptors and co‐receptors. Their ectodomains, which are proteolytically released in the extracellular matrix by shedding, also regulate ...

PSAIA – Protein Structure and Interaction Analyzer [PDF]
BMC Structural Biology, 2008 Abstract Background PSAIA (Protein Structure and Interaction Analyzer) was developed to compute geometric parameters for large sets of protein structures in order to predict and investigate protein-protein interaction sites. Results In addition to most relevant established

PCNA: structure, functions and interactions [PDF]
Oncogene, 1997 Proliferating cell nuclear antigen (PCNA) plays an essential role in nucleic acid metabolism as a component of the replication and repair machinery. This toroidal-shaped protein encircles DNA and can slide bidirectionally along the duplex. One of the well-established functions for PCNA is its role as the processivity factor for DNA polymerase delta and

SUMO Interacting Motifs: Structure and Function [PDF]
Cells, 2021 Small ubiquitin-related modifier (SUMO) is a member of the ubiquitin-related protein family. SUMO modulates protein function through covalent conjugation to lysine residues in a large number of proteins. Once covalently conjugated to a protein, SUMO often regulates that protein’s function by recruiting other cellular proteins.

NMR of RNA - Structure and interactions
Current Opinion in Structural Biology, 2023 RNA was shown to have a more substantial role in the regulation of diverse cellular processes than anticipated until recently. Answers to questions what is the structure of specific RNAs, how structure changes to accommodate different functional roles, and how RNA senses other biomolecules and changes its fold upon interaction create a complete ...

Remark on the vectorlike nature of the electromagnetism and the electric charge quantization
, 1999 In this work we study the structure of the electromagnetic interactions and the electric charge quantization in gauge theories of electroweak interactions based on semi-simple groups. We show that in the standard model of the electroweak interactions the

J/ψ production within a jet in high-energy proton-proton and nucleus-nucleus collisions [PDF]
EPJ Web of ConferencesWe report a systematic study of J/ψ production within a jet in pp and its modification in heavy-ion collisions. Within the framework of leading power factorization formalism of nonrelativistic QCD, we calculate the jet fragmentation function for high-pT ...
