Preparation and Storage

Background: SLITRK1

SLITRK1 (Slit and Trk-like family member 1) is a charter member of the SLITRK family of proteins (1, 2). This family includes six members, all of which contain a slit-like extracellular region, and all of which (save for SLITRK1) contain a Trk-like cytoplasmic region (3). Human SLITRK1 is a type I transmembrane protein 696 amino acids (aa) in length. It contains a 17 aa signal sequence, a 605 aa extracellular domain (ECD), a 21 aa transmembrane segment, and a 53 aa cytoplasmic region. The ECD is characterized by the presence of two leucine-rich domains (LRD) that resemble those found in slit. Each LRD (aa 57‑200; aa 374‑517) contains six leucine-rich repeats (LRRs), followed by a Cys-rich, C-terminal LRR (aa 212‑262; aa 529‑579). The exact function of the LRRs is not known. Based on other LRRs, it might be assumed that they mediate protein-protein-interaction (4). There are multiple, single aa mutations in the ECD. Their significance is unclear (5). One truncating frameshift mutation is known that shows a unique 27 aa substitution after Arg 421 (6). This 448 aa form is associated with Tourette’s Syndrome. As noted, the cytoplasmic region is unique among SLITRK family members. It contains no known signaling motifs, which is in contrast to SLITRK2‑6 which show TrkA-like tyrosine phosphorylation sites. This difference is reflected in their function. SLITRK1 is found in adult neurons of the cerebrum, thalamus and hippocampus. It induces neurite outgrowth whereas SLITRK2‑6 block neurite extension (3). Human SLITRK1 shares 99%, 98% and 99% aa sequence identity with canine, mouse and bovine SLITRK1, respectively.
