A synthetic peptide for use as a blocking control in assays to test for specificity of UPF3 B antibody, Alternative Names: UPF3B control peptide, UPF3B antibody Blocking Peptide, Anti-UPF3B Blocking Peptide, Upf3 Regulator Of Nonsense Transcripts Homolog B Blocking Peptide, HUPF3B Blocking Peptide, MRXS14 Blocking Peptide, RENT3B Blocking Peptide, UPF3X Blocking Peptide, UPF3B, UPFB-3, UPFB 3, UPFB-3 Blocking Peptide, UPFB 3 Blocking Peptide
UPF3B is part of a post-splicing multiprotein complex involved in both mRNA nuclear export and mRNA surveillance. The protein is one of two functional homologs to yeast Upf3p. This protein binds to the mRNA and remains bound after nuclear export, acting as a nucleocytoplasmic shuttling protein. It forms with Y14 a complex that binds specifically 20 nt upstream of exon-exon junctions.
