In version V55, topics with new or revised pathways include: Developmental biology (Activation of anterior HOX genes in hindbrain development during early embryogenesis), Disease (ABC transporter diseases), Gene expression (B-WICH complex positively regulates rRNA expression and tRNA processing), Hemostasis (updated Cell surface interaction at the vascular wall and GPVI-mediated activation cascade), Immune system (IL-6 family signaling and Regulation of BCR signaling by CD22), Metabolism (Response to metal ions, Selenoamino acid synthesis and metabolism as well as updates to Complex I biogenesis and Metabolism of fat-soluble vitamins). Metabolism of proteins has been updated to include Protein repair as well as revisions to Amyloid fiber formation and SUMOylation. Cellular responses to stress includes an update to Macroautophagy, Muscle contraction has been expanded to include Cardiac conduction. Signal transduction includes updates to the RHO GTPases Activate NADPH Oxidases pathway, and Vesicle-mediated transport now covers COPI-mediated anterograde traffic.
