mRNA-decapping enzyme 1A is a protein that in humans is encoded by the DCP1A gene.^[1]

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.^[1]

Interactions

DCP1A has been shown to interact with DCP2^[2] and UPF1.^[2]
