Protein Function (UniProtKB)
Essential for development. May have a critical role in splicing or in controlling alternative splice site use of at least some pre-mRNA in vivo. Not required for all splicing. May play a general role in the condensation or decondensation of chromatin.

Additional Descriptive Data
Antibodies against B52 protein show that it is associated with regions of transcriptionally active chromatin in unstressed and heat shocked animals. It colocalizes with RNA polymerase II but its region of staining brackets the RNA polymerase II signal symmetrically. UV crosslinking studies show that B52 protein is also associated with boundaries of transcriptionally active chromatin on nonpolytene chromosomes.

    Expression is enriched in embryonic gonads.
    B52 has a role in pre-mRNA splicing.
    B52 is referred to as E(Dfd) in FBrf0068180, the motivation behind E(Dfd) was that it was a bit more interesting than B52 and made reference to a phenotype. In subsequent publications B52 is used in favor of consistent nomenclature.
    Both RNA recognition motifs of B52 are required for RNA binding, while the arginine-serine rich domain is not involved in this interaction.
    The distribution of B52 protein at heat-shock loci depends on transcription levels.
    In many cell types increasing the concentration of B52 adversely affects the development of the organism.
    B52 is widely expressed throughout development. B52 accumulates in ovaries where it is packaged into the developing egg and is localised to nuclei by the late blastoderm stage of embryonic development.
    A sequence comparison and numerical analysis of the RRM-containing (RNA recognition motif) proteins suggests that functionally related RRM-containing proteins have significant sequence similarities in their RRMs.
    Identified in an in vitro system as a splicing factor present at low levels in the dsx female-specific splicing complex.
    Encodes a nuclear phosphoprotein, the protein contains an RS domain common to several proteins known to be involved in RNA splicing.
    Involved in pre-mRNA splicing.
    Immunofluorescence of polytene chromosomes reveals the chromatin distribution of the B52 product.
    Isolated in an EMS screen as a dominant modifier of wa.
    An B52 cDNA clone is isolated and sequenced.
