  • 功能：
    RNA-binding protein involved in the histone pre-mRNA processing. Binds the stem-loop structure of replication-dependent histone pre-mRNAs and contributes to efficient 3'-end processing by stabilizing the complex between histone pre-mRNA and U7 small nuclear ribonucleoprotein (snRNP), via the histone downstream element (HDE). Plays an important role in targeting mature histone mRNA from the nucleus to the cytoplasm and to the translation machinery. Stabilizes mature histone mRNA and could be involved in cell-cycle regulation of histone gene expression. Involved in the mechanism by which growing oocytes accumulate histone proteins that support early embryogenesis. Binds to the 5' side of the stem-loop structure of histone pre-mRNAs.

CRL4(WDR23) binds and ubiquitylates SLBP in vitro and in vivo, and this modification activates SLBP function in histone mRNA 3' end processing without affecting its protein levels. PMID: 27203182

    11. C-terminal extension of Lsm4 interacts directly with the histone mRNP, contacting both SLBP and 3'hExo. PMID: 24255165
    12. Data suggest that oligomerization and SLBP phosphorylation regulate SLBP-SLIP1-histone-mRNA complex formation/disassociation; sequential and ordered assembly is required. PMID: 23286197
    13. Using yeast two-hybrid screening, the s identify CT initiation factor-interacting protein (CTIF) as a protein that binds directly to SLBP. SLBP preferentially associates with the CT complex of histone mRNAs consisting of CBP80/CBP20, but not with the eIF4E/eIF4G (ET) complex, as has been proposed. Rapid degradation of histone mRNA on the inhibition of DNA replication requires association of SLBP with CTIF. PMID: 23234701
    14. This paper shows that SLBP is a substrate for the prolyl isomerase Pin1. Pin1, along with PP2A, facilitates dissociation of the SLBP-histone mRNA complex at the end of S-phase, thereby promoting histone mRNA decay and SLBP ubiquitination. PMID: 22907757
    15. This paper describes the biophysical characterization of human SLBP and the SLBP-SLIP1 complex. Human SLBP is an intrinsically disordered protein that is phosphorylated at 23 Ser/Thr sites when expressed in a eukaryotic expression system such as baculovirus. Unphosphorylated human SLBP forms a high affinity heterotetramer with SLIP1 and the SLBP-SLIP1 complex is regulated by SLBP phosphorylation. PMID: 23286197
