Type Comment Proteins
HEN2_ARATH developmental stage Expressed in specific patterns in the inflorescence meristem and developing flowers. Present throughout the inflorescence meristem and in young floral meristems through stage 4. Around stage 5, present within the developing organs of the inner three whorls but absent from sepals. At later stage of floral development, present at a low level in the gynoecium but accumulate strongly in developing ovules.
HEN2_ARATH function ATP-dependent RNA helicase that associates with the RNA exosome complex, with the cap binding complex (CBC) and with the NEXT-like complex. Involved in the degradation of a large number of non-coding nuclear exosome substrates such as snoRNA and miRNA precursors, incompletely spliced mRNAs, and spurious transcripts produced from pseudogenes and intergenic regions (PubMed:25144737). Involved in the maintenance of homeotic B and C gene expression in the reproductive whorls. Regulates floral organ spacing and identity, probably through the regulation of protein synthesis or mRNA degradation (PubMed:11923195).
HEN2_ARATH similarity Belongs to the DExH box helicase family. SKI2 subfamily.
HEN2_ARATH tissue specificity Expressed in inflorescences, leaves, stems, and roots.
