CC -!- FUNCTION: As a component of the decapping complex, involved in the
CC degradation of mRNAs. Essential for postembryonic development.
CC {ECO:0000269|PubMed:17158604, ECO:0000269|PubMed:17485080}.
CC -!- SUBUNIT: Homodimer. Component of the decapping complex. Interacts with
CC DCP2 and DCP5 (PubMed:17158604, PubMed:19855049). Interacts with BCHA1
CC (PubMed:26133670). {ECO:0000269|PubMed:17158604,

CC ECO:0000269|PubMed:26133670}.
CC -!- TISSUE SPECIFICITY: Expressed in seedlings, mostly in root tips, root
CC hairs, and the vascular system. Also present in roots, leaves, stems,
CC and flowers. {ECO:0000269|PubMed:17158604}.
CC -!- DEVELOPMENTAL STAGE: Gradually accumulates during seed maturation to
CC reached maximum levels in dry seeds. Fades progressively upon
CC germination. {ECO:0000269|PubMed:19855049}.
CC -!- DISRUPTION PHENOTYPE: Lethal phenotype at the seedling cotyledon stage,
CC with disorganized veins, swollen root hairs, and altered epidermal cell
CC morphology. {ECO:0000269|PubMed:17158604}.
CC -!- SIMILARITY: Belongs to the DCP1 family. {ECO:0000305}.
