Quaking homolog, KH domain RNA binding (mouse), also known as QKI, is a protein which in humans is encoded by the QKI gene.^[5]^[6]

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.
