Alternate Names for Recombinant Human SLITRK4 Protein, CF

  • DKFZp547M2010
  • SLIT and NTRK-like family, member 4
  • SLIT and NTRK-like protein 4
  • slit and trk like gene 4


SLITRK4 (Slit and Trk-like family member 4) is an approximately 90 kDa type I transmembrane member of the SLITRK family of proteins which contain a slit-like extracellular region and (save for SLITRK1) a Trk-like cytoplasmic region (1). The extracellular domain (ECD) of mature human SLITRK4 contains 6 leucine rich repeats (LRR) followed by a C-terminal LRR domain, followed by 6 more LRR flanked by a pair of N- and C-terminal LRR domains (2, 3). Within the ECD, human SLITRK4 shares 98% amino acid sequence identity with mouse and rat SLITRK4. It is expressed in the testis and multiple regions of the brain, particularly the cerebral cortex, cerebellum, and hippocampus (4). SLITRK4 can suppress neurite outgrowth and promote the formation of excitatory presynaptic structures (3-5).
