LTK (P29376) - Overview - Molecular Target Synopsis
LTK, Leukocyte tyrosine kinase receptor
Enzyme Classification 188.8.131.52
Also Known as LTK_HUMAN, LTK, TYK1
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. Homodimer when bound to ligand (Probable). Part of a complex including LTK, TNK2 and GRB2, in which GRB2 promotes LTK recruitment by TNK2.
