WB Use a concentration of 0.5 - 2 µg/ml. Detects a band of approximately 95 kDa (predicted molecular weight: 91 kDa).


  • FunctionOrphan receptor with a tyrosine-protein kinase activity. The exact function of this protein is not known. Studies with chimeric proteins (replacing its extracellular region with that of several known growth factor receptors, such as EGFR and CSFIR) demonstrate its ability to promote growth and specifically neurite outgrowth, and cell survival. Signaling appears to involve the PI3 kinase pathway. Involved in regulation of the secretory pathway involving endoplasmic reticulum (ER) export sites (ERESs) and ER to Golgi transport.
  • Tissue specificityExpressed in non-hematopoietic cell lines and T- and B-cell lines.
  • Involvement in diseaseNote=Genetic variations in LTK that cause up-regulation of the PI3K pathway may possibly contribute to susceptibility to abnormal proliferation of self-reactive B cells and, therefore, to systemic lupus erythematosus (SLE). SLE is a chronic, inflammatory and often febrile multisystemic disorder of connective tissue, thought to represent a failure of the regulatory mechanisms of the autoimmune system.
  • Sequence similaritiesBelongs to the protein kinase superfamily. Tyr protein kinase family. Insulin receptor subfamily.
    Contains 1 protein kinase domain.

    Predicted band size : 91 kDa
    Observed band size : 95 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 120 kDa,33 kDa,40 kDa,50 kDa,63 kDa. We are unsure as to the identity of these extra bands.
