Summary: Ubiquitination, similar to phosphorylation and acetylation, plays a crucial role in regulating various cell processes. Understanding how pathogens manipulate host ubiquitination processes is important for vaccine development and disease treatment. Pathogenic bacteria encode effector proteins targeting the host ubiquitin machinery to disrupt host defense processes.

Summary: Adhesion and colonization of host cells by pathogenic bacteria rely on protein-protein interactions (PPIs). This study developed a filtering process to obtain a reliable list of domains and motifs participating in PPIs between bacteria and human cells. Structural analysis revealed that human proteins involved in these interactions are rich in alpha helix and disordered regions. The most significant domain-domain interactions were validated, but verifying domain-motif interactions was more challenging. Post-translational modifications, especially phosphorylation, also play a role in these interactions.

Summary: The liver is a non-immunological organ involved in metabolic activities, nutrient storage, and detoxification. Resident immune cells in the liver drive immunological reactions and certain microRNAs are associated with the immune response to pathogens, although the exact mechanism of miRNA interference in these interactions remains unclear.

Summary: The COVID-19 pandemic has revealed the limitations of medical and research institutions in managing emerging infectious diseases. Predicting virus-host interactions through host range prediction and protein-protein interaction prediction can enhance our understanding of infectious diseases. Although multiple algorithms have been developed for this purpose, there are still challenges that need to be addressed. Despite the difficulties, bioinformatics can play a significant role in advancing research on infectious diseases and human health.

Summary: Protein-protein interactions play important roles in cellular processes. To address the limited knowledge of host-pathogen interactomes, we developed HPIPred, a numerical encoding-based host-pathogen PPI prediction tool. Through screening the entire proteomes of Homo sapiens and Pseudomonas aeruginosa PAO1, we generated a highly connected network topology of host-pathogen interactome using HPIPred.

Summary: Interactions between MEK1, B-Raf, and KSR1 are crucial for Ras/Raf/MEK/ERK signaling. Molecular dynamics simulations reveal that the proline-rich loop of MEK1 is essential for the phosphorylation of MEK1 activation loop. In the inactive B-Raf/MEK1 complex, the collapsed A-loop of B-Raf interacts with the P-rich loop and A-loop of MEK1, preventing phosphorylation. In the active B-Raf/MEK1 complex, the P-rich loop moves with the extended A-loop of B-Raf, leading to increased A-loop fluctuation and phosphorylation. KSR1/MEK1 complex has fewer interactions between KSR1 alpha G-helix and MEK1 A-loop, resulting in a more flexible A-loop.

Summary: This article discusses the principles and applications of allosteric activating mutations and drugs, using examples from the Ras signaling network. Specifically, it focuses on Abl kinase mutations that shift the conformation towards an active state, leading to competition between high affinity ATP and drug binding. Recent pharmacological innovation includes allosteric inhibitors and allosteric heterobifunctional degraders that can destroy targets. The design of chemical linkers in bifunctional degraders allows precise coordination between the target protein and the E3 ubiquitin ligase, enabling innovative drug discovery.

Summary: Immunity plays a crucial role in both neurodevelopmental disorders and cancer, as the immune and nervous systems coevolve during embryonic development. Dysregulated signaling caused by germline or embryonic mutations can lead to changes in chromatin organization and gene accessibility, affecting the expression of essential genes in neurodevelopment. Similarly, dysregulated signaling resulting from somatic mutations contributes to cancer development. Both conditions involve small GTPases and their pathways, as well as dysregulation of TLRs, IL-1, GIT1, and FGFR signaling pathways. However, key differentiating factors are the timing and level of perturbation in specific cell types, indicating chromatin reorganization.

Summary: Bcr-Abl, a nonreceptor tyrosine kinase, plays a crucial role in leukemias, particularly chronic myeloid leukemia (CML). The fusion of Bcr and Abl leads to constitutive activation of Bcr-Abl. Oligomerization of Bcr-Abl is critical for its membrane clustering, MAPK signaling, and cell proliferation. Understanding the structural basis of Bcr-Abl oligomerization can guide the development of novel drugs targeting this process.

Summary: Neurodevelopmental disorders (NDDs) and cancer have similarities in terms of proteins, pathways, and mutations, but have different clinical symptoms. However, individuals with NDDs have a higher likelihood of developing cancer later on. This review explores how shared features can result in different medical conditions and why having an NDD first can increase the chances of malignancy.

Summary: Epidemiological studies show that individuals with neurodevelopmental disorders are more likely to develop certain types of cancer. While these disorders and cancer share proteins, pathways, and mutations, they differ in clinical outcomes. The key factor determining clinical outcome is signaling strength, with strong signaling promoting cell proliferation in cancer and moderate signaling affecting differentiation in neurodevelopmental disorders.

Summary: Researchers have used extensive molecular dynamics simulations to decipher the activation and autoinhibition mechanism of c-Abl. The myristoyl group serves as a switch for c-Abl inhibition/activation, and precise SH2/N-lobe interaction is required for full activation. Bcr-Abl allosteric drugs mimic the endogenous myristoyl-mediated autoinhibition state and alter the active-site conformation, affecting the action of ATP-competitive drugs.

Summary: In this study, it was found that the DNA damage response in Mycobacterium tuberculosis differs from well-studied model bacteria. The DNA repair helicase UvrD1 in Mtb is activated through a redox-dependent process and is closely associated with the homo-dimeric Ku protein. Additionally, Ku protein is shown to stimulate the helicase activity of UvrD1.
