WebJan 29, 2024 · RLCKs likely function as a direct link between activated receptors and intracellular MAPK cascades, as indicated by the recently identified chitin signaling pathway (Yamada et al., 2016). However, the RLCKs upstream of MAPK cascades in many other receptor signaling pathways still need to be identified. The structure of chitin was determined by Albert Hofmann in 1929. Hofmann hydrolyzed chitin using a crude preparation of the enzyme chitinase, which he obtained from the snail Helix pomatia.
