Protein Family Models

CHASE3 is an extracellular sensory domain, which is present in various classes of transmembrane receptors that are parts of signal transduction pathways in bacteria. Specifically, CHASE3 domains are found in histidine kinases, adenylate cyclases, methyl-accepting chemotaxis proteins and predicted diguanylate cyclases/phosphodiesterases [1]. This domain recognises pyrene (Matilla et al., FEMS Microbiology Reviews, fuab043, 45, 2021, 1. https://doi.org/10.1093/femsre/fuab043). [1]. 12486065.

sensor histidine kinase, part of a two-component regulatory system, functions as a protein kinase that phosphorylates a target protein in response to various signals; similar to phytochrome, a class of photoreceptor found in plants, bacteria and fungi, which are used to detect light.
