About DCP2

Cytogenetic location: 5q22.2 Genomic coordinates (GRCh38): 5:112,976,798-113,022,195 (from NCBI)

This gene has 9 transcripts (splice variants) and 203 orthologues. Ubiquitous expression in lymph node (RPKM 7.7), placenta (RPKM 6.8) and 24 other tissues.

Summary

The protein encoded by this gene is a key component of an mRNA-decapping complex required for degradation of mRNAs, both in normal mRNA turnover, and in nonsense-mediated mRNA decay (NMD). It removes the 7-methyl guanine cap structure from mRNA, prior to its degradation from the 5' end. Alternatively spliced transcript variants encoding different isoforms have been noted for this gene.[provided by RefSeq, Jun 2011]
