Protein
Smu-2 suppressor of mec-8 and unc-52 protein
Organism
Caenorhabditis elegans
Function
Auxiliary spliceosomal protein that regulates selection of alternative splice sites in a small set of target pre-mRNA species (Probable). Selectively regulates alternative splicing of unc-52 exon 17. Thus, smu-2 mutants selectively suppress the effects of unc-52 nonsense mutations in exon 17 by promoting the accumulation of unc-52 isoforms that lack exon 17. In contrast, smu-2 mutants do not suppress the effects of an unc-52 mutation that affects the 5' splice site of exon 16. Required for normal accumulation of smu-1 (PubMed:15254247).
Similarity
Belongs to the RED family.
