General description

Upf1 is part of a post-splicing multiprotein complex involved in both mRNA nuclear export and mRNA surveillance. mRNA surveillance detects exported mRNAs with truncated open reading frames and initiates nonsense-mediated mRNA decay (NMD). When translation ends upstream from the last exon-exon junction, this triggers NMD to degrade mRNAs containing premature stop codons. Upf1 is located only in the cytoplasm. When translation ends, it interacts with the protein that is a functional homolog of yeast Upf2p to trigger mRNA decapping.


This antibody detects Upf1.


KLH-conjugated synthetic linear peptide corresponding to Upf1.


Anti-Upf1 Antibody is a rabbit polyclonal antibody for detection of Upf1 also known as ATP-dependent helicase RENT1 ,Nonsense mRNA reducing factor 1, Up-frameshift suppressor 1 homolog & has been validated in WB.
