Protein Family Models

Double cache domain 1 covers the last three strands from the membrane distal PAS-like domain, the first two strands of the membrane proximal domain, and the connecting elements between the two domains [2]. This domain when present in chemoreceptors recognise several signals such as proteinogenic amino acids, GABA, Histamine and polyamines, decanoic acid, Autoinducer-2, purine derivatives, quaternary amines, citrate and taurine, among others. When associated with histidine kinases, it recognises C3/C4-dicarboxylic acids, Spermine, guanosine and Autoinducer-2 (Mantilla et al., FEMS Microbiology Reviews, fuab043, 45, 2021, 1 https://doi.org/10.1093/femsre/fuab043).

This domain is thought to transduce the signal to CheA since it is highly conserved in very diverse MCPs. [1]. 1601874. Sequence and characterization of Bacillus subtilis CheW. Hanlon DW, Marquez-Magana LM, Carpenter PB, Chamberlin MJ, Ordal GW;. J Biol Chem 1992;267:12055-12060. (from Pfam)

methyl-accepting chemotaxis protein (MCP) is a bacterial receptor that mediates chemotaxis to diverse signals, responding to changes in the concentration of attractants and repellents in the environment by altering swimming behavior
