    text
  • localized in mitotic cells, radial glial cells and radial processes
  • the kinase fragment of DCLK1 is translocated into the nucleus upon hyperosmotic stresses and the kinase efficiently phosphorylates JDP2, a possible target in the nucleus, with the aid of histones
  • in human intestinal epithelium, DLCK1-positive cells form a subpopulation of non-proliferating neuroendocrine cells with apical brush border similar to that in enterocytes
  • basic FUNCTION
  • participating in functions of the mature nervous system
  • involved in a calcium-signaling pathway controlling neuronal migration in the developing brain
  • acting as a protein serine/threonine kinase
  • acting as a receptor signaling protein
  • may have a role in migrating neurons
  • critically involved in dynamic rearrangement of the cytoskeletal machinery that allow migration
  • playing a unique role in mitotic spindle integrity during early neurogenesis in radial glial cell proliferation and their radial process stability
  • is a functionally pertinent gene involved in human memory and cognitive functions
  • unique roles for DCLK1 in adult neurogenesis
  • role for DCX and DCLK1 in enabling microtubules to overcome retrograde actin-based forces, thereby facilitating the ability of the growth cone to carry out its crucial path-finding functions
  • is a physiologically relevant regulator of anabolic bone formation
  • CDH13, GRM8, ANK2, SLC16A6, ARSG, RIMBP2 and DCLK1 having role in hearing function
  • importance of DCLK1 function in tumorigenesis and cancer (PMIDC:
  • functions in multiple stages of neural development including radial migration and axon growth of cortical neurons
  • DCLK1 kinase activity negatively regulates microtubule polymerization
  • is a microtubule-associated kinase
  • tuft cells, via DCLK1, are important responders to bacterial-induced colitis by enhancing epithelial repair responses, which in turn limits bacterial infiltration into the mucosa
  • DCLK1 autophosphorylates a residue within its C-terminal tail to restrict its kinase activity and prevent aberrant hyperphosphorylation within its microtubule-binding domain
  • DCLK1 modulates likely its kinase activity to tune its microtubule-binding affinity
  • roles of DCLK1 in augmenting SARS-CoV-2 viremia, inflammatory cytokine expression, and dysregulation of immune cells involved in innate immunity
  • DCLK1 regulates tumorigenesis and epithelial&
