Decapping is a key step in general and regulated mRNA decay. The protein encoded by this gene is a decapping enzyme. This protein and another decapping enzyme form a decapping complex, which interacts with the nonsense-mediated decay factor hUpf1 and may be recruited to mRNAs containing premature termination codons. This protein also participates in the TGF-beta signaling pathway.[5]

Interactions

edit

DCP1A has been shown to interact with DCP2[6] and UPF1.[6] It has also been shown to colocalize with GW182, and other markers of P-body.[7] Human DCP1A is heterotrimeric,[8] and makes contacts with the scaffold EDC3/4.[9] The Arabidopsis thaliana homolog interacts with the plant specific type XI myosin motor protein.[10]
