Summary: Predicted to enable identical protein binding activity; kinesin binding activity; and mRNA binding activity. Predicted to be involved in deadenylation-dependent decapping of nuclear-transcribed mRNA; deadenylation-independent decapping of nuclear-transcribed mRNA; and protein localization to cytoplasmic stress granule. Predicted to act upstream of or within positive regulation of transcription, DNA-templated and transforming growth factor beta receptor signaling pathway. Located in P-body. Is expressed in several structures, including genitourinary system; limb; liver; muscle tissue; and spleen. Orthologous to human DCP1A (decapping mRNA 1A).

Recruitment of DCP1A and DCP2 increases the mRNA degradation capacity of the maturing oocyte so that by the 2-cell stage, most of the maternal mRNA is degraded.
Title: Losing mom's message: requirement for DCP1A and DCP2 in the degradation of maternal transcripts during oocyte maturation.
The results showed that DCP1A and DCP2 are critical in the transition from mRNA stability to instability during meiotic maturation and that mRNA degradation must be successful to execute the oocyte-to-zygote transition.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
