QKI belongs to a family of RNA-binding proteins called STAR proteins for Signal Transduction and Activation of RNA.[7] They have an HNRNPK homology (KH) domain embedded in a 200-amino acid region called the GSG domain. Other members of this family include SAM68 (KHDRBS1) and SF1 .[8] Two more new members are KHDRBS3[9] and KHDRBS2.[10]

The QKI gene is implicated as being important in schizophrenia,[11][12] and QKI controls translation of many oligodendrocyte-related genes.
