JAK #

  • Consists of JAK1-3 and Tyk2.
  • Its ligands are typically Cytokines.
  • JAK-STAT is involved in immunity, proliferation, apoptosis, oncogenesis (regulating/inhibiting), etc.
  • Non-receptor tyrosine kinase, however, they still localize(/attach I assume) to the C-terminus of… receptors. But they are not a receptor themselves and are found in the cytosol.
  • pSTAT then activates PI3K, Ras pathway, and the proteasome @ ISRE and GAS.
    • Increases p21 expression.
  • JAK2 has no Src domains.
