DescriptionDescriptionSpecificity This antibody recognizes human, mouse, and rat QKI-5. It cross-reacts with QKI-6,
QKI-7, and QKI-7b. Background QKI (also called Protein Quaking or HqkI) is an RNA binding protein that plays a central role in myelinization. QKI acts by regulating pre-mRNA splicing, mRNA export, mRNA stability, and protein translation and is itself regulated by alternative splicing. QKI is expressed in the frontal cortex of brain; it is shown to be downregulated in the brains of schizophrenic patients. Function RNA-binding protein that plays a central role in myelinization (PubMed:16641098). Binds to the 5'-NACUAAY-N(1,20)-UAAY-3' RNA core sequence. Regulates target mRNA stability (PubMed:23630077). In addition, acts by regulating pre-mRNA splicing, mRNA export and protein translation. Required to protect and promote stability of mRNAs such as MBP and CDKN1B. Regulator of oligodendrocyte differentiation and maturation in the brain that may play a role in myelin and oligodendrocyte dysfunction in schizophrenia (PubMed:16641098). 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 (By similarity). {UniProtKB:Q9QYS9, PubMed:16641098, PubMed:23630077}.
