靶點詳情

  • 功能：
    RNA-binding protein that plays a central role in myelinization. Also required for visceral endoderm function and blood vessel development. 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, as well as cellular processes including apoptosis, cell cycle, glial cell fate and development. 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. May also play a role in smooth muscle development.; Isoform 1 is involved in regulation of mRNA splicing of MAG pre-mRNA by acting as a negative regulator of MAG exon 12 alternative splicing.; Isoform 3 can induce apoptosis, while heterodimerization with other isoforms results in nuclear translocation of isoform 3 and suppression of apoptosis.; Isoform 4 acts as a translational repressor for GLI1.

    1. These data collectively indicate that Qki5 regulates communication between neural stem cells by mediating numerous RNA processing events and suggest new links between splicing regulation and neural stem cell states. PMID: 29021239
    2. this study explores how levels of two isoforms, nuclear Quaking-5 (Qk5) and cytoplasmic Qk6, are regulated in mouse myoblasts. Qk5 and Qk6 proteins have distinct functions in splicing and translation, respectively, enforced through differential subcellular localization. PMID: 29021242

    12. The study provides evidence that cytoplasmic quaking I-6 acts upstream of hnRNP F/H, which forms a novel pathway to control alternative splicing in myelinating glia. PMID: 24792162

    Defects in Qki are the cause of quakingviable (qkv). Qkv is a spontaneous mutation resulting in hypomyelinization of the central and peripheral nervous systems. Mutant mice develop normally until postnatal day 10 when they display rapid tremors or 'quaking' that is especially pronounced in hindlimbs and experience convulsive tonic-clonic seizures as they mature (PubMed:8589716). Mice with qkv specifically lack isoform 3 and isoform 4 in myelin-forming cells, while isoform 1 is lacking in oligodendrocytes of severely affected tracts (PubMed:12888522). Mice with qkv also lack the PRKN gene product, suggesting that the absence of PRKN may also affect the phenotype (PubMed:15014970).

It shuttles between the cytoplasm and the nucleus.; [Isoform 3]: Cytoplasm. Nucleus. Note=Isoform 3 localizes predominantly in the cytoplasm and at much lower levels in nucleus.; [Isoform 4]: Cytoplasm. Nucleus. Note=Isoform 4 localizes both in the cytoplasm and nucleus.
