NCBI Protein Information
radical SAM domain-containing protein / GCN5-related N-acetyltransferase (GNAT) family protein
NCBI Summary
A subunit of Elongator, a histone acetyl transferase complex, consisting of six subunits (ELP1#AeiELP6), that copurifies with the elongating RNAPII in yeast and humans. Three Arabidopsis thaliana genes, encoding homologs of the yeast Elongator subunits ELP1, ELP3 (histone acetyl transferase), and ELP4 are responsible for the narrow leaf phenotype in elongata mutants and for reduced root growth that results from a decreased cell division rate. Two lines with RNAi constructs directed against HAG3 grow normally and can produce root calli, but have defects in agrobacterium-mediated transformation.

UniProt Comments
Histone acetyltransferase component of the large multiprotein complex Elongator that is involved in the regulation of transcription initiation and elongation (PubMed:20080602). May also have a methyltransferase activity (PubMed:20080602). Promotes organs development by modulating cell division rate (PubMed:20080602). Required for auxin distribution or signaling (PubMed:20080602). Required for meristem cell cycle activation at the time of germination (PubMed:23969312). Probably required for DNA replication-coupled histone acetylation (PubMed:22026817). Involved in tRNA wobble uridine modification (PubMed:20398216). Mediates the establishment of leaf polarity independently of AS2 and the ta-siRNA-related pathway (PubMed:21700721). Potential a-tubulin acetyltransferase (PubMed:22404109). Negatively regulates the expression of genes that participate in UV-B responses, such as DNA repair enzymes and enzymes that participate in sunscreen pigment biosynthesis (PubMed:25907565).
