motifs/domains
  • two N-terminal membrane-spanning domains
  • a long C terminus, which harbors a dual-specificity serine/threonine/tyrosine kinase domain, and a di-acidic ER export motif, used by LMTK2 for its efficient export from the ER
  • HOMOLOGY
    interspecies homolog to murine apoptosis associated tyrosine kinase
    Homologene
    FAMILY

    text
  • integral to membrane
  • localizes to cytoplasmic membrane vesicles and to perinuclear recycling endosomes
  • serine/threonine kinase predominantly localized to endosomal compartments
  • basic FUNCTION
  • apoptosis associated tyrosine kinase
  • involved in neural development and functions during the early postnatal period
  • playing important roles in NGF-TrkA signaling
  • functioning as a myosin VI-interacting protein, involved in endosomal membrane trafficking
  • critical for the transition of endocytosed membrane vesicles from early endosomes to recycling endosomes, suggesting an involvement of myosin VI in this pathway
  • LMTK2 may regulate the activity of kinesin-1 motor function and SMAD2 signalling
  • transmembrane protein with serine and threonine but not tyrosine kinase activity
  • involved in the trafficking of the CFTR ion channel, the androgen receptor, as well as modulating neurodegeneration
  • CELLULAR PROCESS cell life, cell death/apoptosis

    small molecule
  • ATP
  • protein
  • interaction of myosin VI with LMTK2
  • regulates a known pathway that controls phosphorylation of kinesin-1 light chain-2 (KLC2) by glycogen synthase kinase-3&
  • 946; (GSK3B)
  • CFTR is a substrate of LMTK2, and phosphorylates CFTR-Ser(737) in human airway epithelial cells
  • cell & other
