Deciphering Spatial Protein–Protein Interactions in Brain Using Proximity Labeling
In Brief PL has emerged as a powerful tool to identify proteomes in distinct cell types in brain as well as proteomes and protein–protein interaction networks in structures difficult to isolate, such as the synaptic cleft, axonal projections, or astrocyte–neuron junctions. Here, we review recent advances in PL methods and their application to neurobiology.An Expanding Repertoire of Protein Acylations
In Brief In this work, we give a general overview of the 12 main protein acylations, also including novel acylations, such as benzoylation and 2-hydroxyisobutyrylation. We summarize the recent advances in protein acylation, mainly focus on their substrates, enzymes, biological functions, and novel detecting methods and related diseases, especially in cancer. We believe that the review will provide an unprecedented and comprehensive view of protein acylations and bring important reference significance for future research.Subcellular Transcriptomics and Proteomics: A Comparative Methods Review
In Brief The interior of the cell is molecularly crowded. Its compartmentalization within organelles enables the regulation of biochemical processes and allows multifunctionality of proteins and RNAs. Subcellular information can thus give insights into the function of these biomolecules. Multiple techniques to measure such information have been established, with ever-increasing throughput and sensitivity. These techniques are covered in this review, and demonstrating their application is providing valuable insights into cellular biology, such as aiding our understanding of single-cell heterogeneity and posttranslational modifications.
