Background: SLITRK3

SLITRK3 (Slit and Trk-like family member 3) is an approximately 120 kDa type I transmembrane member of the SLITRK family of proteins which contain a Slit-like extracellular region and a Trk-like cytoplasmic region (1). The extracellular domain (ECD) of mature mouse SLITRK3 contains 6 leucine rich repeats (LRR), a C‑terminal LRR domain, and 6 more LRR flanked by a pair of N- and C‑terminal LRR domains (2, 3). Within the ECD, mouse SLITRK3 shares 98% and 99.5% amino acid sequence identity with human and rat SLITRK3, respectively. SLITRK3 is expressed in multiple regions of the brain, particularly the cerebral cortex and hippocampus (4). SLITRK3 can suppress neurite outgrowth and promote the formation of inhibitory presynaptic structures (3-6). It localizes post-synaptically and binds to PTP-delta and PTP-sigma on pre-synaptic inhibitory terminals (4, 5). SLITRK3 is up-regulated during the development of gastrointestinal stromal tumors (7).
