    Source / Purification

    Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Arg160 of human SLBP protein. Antibodies are purified by protein A and peptide affinity chromatography.

    Background

    Stem-loop binding protein (SLBP) is the mammalian orthologue of Xenopus SLBP1, a post-transcriptional regulator of histone mRNA. SLBP binds the conserved stem-loop structure at the 3’ end of replication-dependent histone mRNAs. SLBP binding aids in the 3’ end processing of histone pre-mRNA in association with U7 snRNP and the zinc finger protein hZFP100 (1,2), as well as translation and transport of histone mRNA (3).

    The expression of replication-dependent histone genes peaks during S phase of the cell cycle. Mammalian SLBP is also cell cycle regulated in most somatic cells, but not in mouse oocytes or embryos, indicating a potential role for SLBP in chromatin organization and remodeling (4).

    Phosphorylation of SLBP at Thr61 by CDK1 regulates SLBP stability by targeting the protein for degradation upon completion of DNA synthesis (5). SLBP association with histone mRNA maintains its stability, and is regulated by the peptidyl-prolyl isomerase, Pin1, and PP2A phosphatase (6,7).

    Alternate Names

    hairpin binding protein, histone; HBP; histone binding protein; Histone RNA hairpin-binding protein; histone stem-loop binding protein; Histone stem-loop-binding protein; SLBP; stem-loop (histone) binding protein; stem-loop binding protein
