Protein
RNA cytidine acetyltransferase
Gene
l(1)G0020
Organism
Drosophila melanogaster (Fruit fly)
Status
Functioni
RNA cytidine acetyltransferase with specificity toward both 18S rRNA and tRNAs. Catalyzes the formation of N4-acetylcytidine (ac4C) in 18S rRNA. Required for early nucleolar cleavages of precursor rRNA at sites A0, A1 and A2 during 18S rRNA synthesis. Catalyzes the formation of ac4C in serine and leucine tRNAs. Requires a tRNA-binding adapter protein for full tRNA acetyltransferase activity but not for 18S rRNA acetylation (Probable). Polycomb group (PcG) protein. PcG proteins act by forming multiprotein complexes, which are required to maintain the transcriptionally repressive state of homeotic genes throughout development. PcG proteins are not required to initiate repression, but to maintain it during later stages of development. They probably act via the methylation of histones, rendering chromatin heritably changed in its expressibility (PubMed:11493925).UniRule annotation1 Publication

Interactioni
Subunit structurei
Component of the PRC1 complex (PSC, PC, PH and dRING1) in 0-12 hours Drosophila embryos. This complex is distinct from the Esc/E(z) complex, which contains many other PcG proteins like Esc, E(z), Su(z)12, Rpd3, Caf1-55 and probably Pho. The two complexes however cooperate and interact together during the first 3 hours of development to establish PcG silencing.
