The SLIT and NTRK-like protein (SLITRK) family consists of six brain-specific transmembrane proteins (SLITRK1–6) that possess extracellular LRR domains homologous to the axon guidance molecule Slit and intracellular C-terminal tyrosine residues with surrounding sequences homologous to the Trk family (Aruga & Mikoshiba 2003). SLITRKs have been implicated in the modulation of neuronal process outgrowth promoting neuronal survival and in synapse formation (Linhoff et al. 2009). They exhibit synaptogenic activities through their interactions with specific LAR-RPTP members. All SLITRKs can interact with Receptor-type tyrosine-protein phosphatase delta (PTPRD), and SLIK1-3 at least can also interact with PTPRS (Meyer et al. 2004). SLITRK3 can induce inhibitory, but not excitatory, presynaptic differentiation whereas other family members induce both excitatory and inhibitory presynapses (Takahashi et al. 2012).
SLITRK1 variants are associated with Tourette’s syndrome (Abelson et al. 2005) and Trichotillomania (Zuchner et al. 2006) and obsessive compulsive disorders (OCDs). SLITRK2 is a candidate gene for schizophrenia (Piton et al. 2011) and bipolar disorder.
