Entrez ID 65109
Gene name UPF3B regulator of nonsense mediated mRNA decay
Gene symbol UPF3B
Synonyms (NCBI Gene)
HUPF3BMRX62MRX82MRXS14RENT3BUPF3BP1UPF3BP2UPF3BP3UPF3XUpf3p-X
Chromosome X
Chromosome location Xq24
Summary This gene encodes a protein that is part of a post-splicing multiprotein complex involved in both mRNA nuclear export and mRNA surveillance. The encoded protein is one of two functional homologs to yeast Upf3p. mRNA surveillance detects exported mRNAs wit
