Anti-RRP1B Antibody Picoband® Fluoro594 Conjugated

RRP1B (ribosomal RNA processing 1 homolog B), also known as KIAA0179, is a human gene which is located on Chromosome 21. Enables transcription coactivator activity. Involved in several processes, including cellular response to virus; positive regulation by host of viral transcription; and positive regulation of transcription by RNA polymerase II. Located in chromosome; granular component; and nucleoplasm.

Pre-mRNA processing factor involved in disassembly of spliceosomes after the release of mature mRNA. In cooperation with TFIP11 seem to be involved in the transition of the U2, U5 and U6 snRNP-containing IL complex to the snRNP-free IS complex leading to efficient debranching and turnover of excised introns.
