QKI HKQ

QKI

The protein encoded by this gene is an RNA-binding protein that regulates pre-mRNA splicing, export of mRNAs from the nucleus, protein translation, and mRNA stability. The encoded protein is involved in myelinization and oligodendrocyte differentiation and may play a role in schizophrenia. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2014],

Disease:Deletion of the QKI gene may play a role in astrocytic tumors.,Disease:May play a role in genetic susceptibility to schizophrenia. QKI levels of some isoforms such as isoform 6, are frequently down-regulated in schizophrenic patients.,Function:RNA-binding protein that plays a central role in myelinization. Binds to the 5'-NACUAAY-N(1,20)-UAAY-3' RNA core sequence. Acts by regulating pre-mRNA splicing, mRNA export, mRNA stability and protein translation. Required to protect and promote stability of mRNAs such as MBP and CDKN1B which promotes oligodendrocyte differentiation. Participates in mRNA transport by regulating the nuclear export of MBP mRNA. Also involved in regulation of mRNA splicing of MAG pre-mRNA. Acts as a translational repressor.,PTM:Methylated by PRMT1.,PTM:Tyrosine phosphorylated at its C-terminus, probably by FYN. Phosphorylation leads to decreased mRNA-binding affinity, affecting transport and/or stabilization of MBP mRNA.,sequence Caution:Chimeric cDNA.,similarity:Contains 1 KH domain.,subunit:Homodimer. Does not require RNA to homodimerize. Able to heterodimerize with BICC1.,tissue specificity:Expressed in the frontal cortex of brain.,

Nucleus . Cytoplasm .

Expressed in the frontal cortex of brain. Down-regulated in the brain of schizophrenic patients.
