Protein chemical shift assignments of the unbound and RNA-bound forms of the alternative splicing factor SUP-12 from C. elegans

Protein chemical shift assignments of the unbound and RNA-bound forms of the alternative splicing... The splicing factor SUP-12 from Caenorhabditis elegans binds to regulatory RNA elements in pre-mRNA in order to generate tissue-specific alternative splicing for genes such as the fibroblast growth factor receptor egl-15. In nematode muscle cells, SUP-12 promotes the use of a mutually exclusive exon to impart variant binding specificity to the EGL-15 extracellular protein domain. Here we report the side chain and backbone 1H, 13C and 15N chemical shift assignments for the bacterially expressed RNA recognition motif domain from SUP-12, both in isolation as well as bound to a short RNA derived from the intron sequence between exon 4 and exon 5B of egl-15. Comparison of protein chemical shift values for both the backbone and side chain nuclei, coupled with secondary chemical shift analysis, reveal initial details of the RNA recognition. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Biomolecular NMR Assignments Springer Journals

Abstract

The splicing factor SUP-12 from Caenorhabditis elegans binds to regulatory RNA elements in pre-mRNA in order to generate tissue-specific alternative splicing for genes such as the fibroblast growth factor receptor egl-15. In nematode muscle cells, SUP-12 promotes the use of a mutually exclusive exon to impart variant binding specificity to the EGL-15 extracellular protein domain. Here we report the side chain and backbone 1H, 13C and 15N chemical shift assignments for the bacterially expressed RNA recognition motif domain from SUP-12, both in isolation as well as bound to a short RNA derived from the intron sequence between exon 4 and exon 5B of egl-15. Comparison of protein chemical shift values for both the backbone and side chain nuclei, coupled with secondary chemical shift analysis, reveal initial details of the RNA recognition.
