  • In the case of classical MAP kinases, the activation loop contains a characteristic TxY (threonine-x-tyrosine) motif (TEY in mammalian ERK1 and ERK2, TDY in ERK5, TPY in JNKs, TGY in p38 kinases) that needs to be phosphorylated on both the threonine and the tyrosine residues in order to lock the kinase domain in a catalytically competent conformation.

  • Pectinase, an enzyme responsible for degrading pectin present in the cell wall releases WAKs, this became the primary suggestion that WAKs are bound to pectin within the cell wall. (wikipedia.org)
  • However, since WAKs are also required for cell growth by binding to long pectin polymers for plant development and also pectin fragments for wounding response, no means has been found as to how WAKs differentiates between the two types of pectins to either initiate cell elongation or protection. (wikipedia.org)
  • A dominant WAKs allele that requires a pectin binding domain and kinase activity was shown to induce a stress response, however, this allele was suppressed with a null allele of pectin methyl-esterase (pme) which prevented the removal of the methyl groups that polymerize pectin to a de-esterified polymer hence resulting in an esterified pectin. (wikipedia.org)
  • WAKs are found in various plants and crops like rice, and maize. (wikipedia.org)
  • WAKs' association with cell wall is very strong (having covalent link to pectin), such that its release from the cell wall requires enzymatic digestion. (wikipedia.org)

(wikipedia.org)
  • The interaction of pectin polyanion with the cell wall or plasmalemma could induce conformational changes in the pectin polymers that affect their gelling and swelling behavior in the presence of the calcium and the binding of pectins to WAK1 in the presence of calcium could result in muro disturbances of the pectin network that could generate signals within the cell wall.
