Version 60 Released

New and Updated Pathways. In version V60, topics with new or revised pathways include: Cell cycle (Cyclin D associated events in G1), Cell-cell communication (SDK interactions), Cellular response to external stimuli (HSP90 chaperone cycle for steroid hormone receptors (SHR)), Disease (Diseases of Mismatch Repair), Gene Expression (TP53 Regulates Transcription of Genes Involved in G1 Cell Cycle Arrest and Transcriptional Regulation by the CBFB:RUNX3 complex), Immune System (Butyrophilins and Regulation of complement cascade), Metabolism (Synthesis of IP2, IP, and Ins in the cytosol, Synthesis of PIPs at the early endosome membrane, Synthesis of PIPs at the ER membrane, Synthesis of PIPs at the late endosome membrane, and Synthesis of PIPs at the plasma membrane), Metabolism of proteins (CREB3 factors activate genes, Neddylation, Protein ubiquitination, and SUMOylation of chromatin organizing proteins), Mitophagy (Receptor Mediated Mitophagy), Neuronal System (Receptor protein tyrosine phosphatases interactions), Organelle biogenesis and maintenance (Cristae formation), and Transport of small molecules (Mitochondrial calcium ion transport).

Annotation Statistics. Reactome comprises 10,754 human reactions organized into 2,132 pathways involving 10,907 proteins encoded by 10,658 different human genes, 1,763 small molecules, and 10,748 complexes. These annotations are supported by 26,384 literature references. We have projected these reactions onto 115,881 orthologous proteins, creating 20,701 orthologous pathways in 18 non-human species. Version 60 has annotations for 1,503 protein variants (mutated proteins) and their post-translationally modified forms, derived from 285 proteins. These have been used to annotate 506 disease-specific complexes and 906 disease-specific reactions organized into 453 pathways and subpathways, and tagged with 294 Disease Ontology terms.
