Summary

NAA80 (N-alpha-acetyltransferase 80, NatH catalytic subunit, HGNC:30252) is a protein-coding gene on chromosome 3p21.31, encoding N-alpha-acetyltransferase 80 (Q93015). N-alpha-acetyltransferase that specifically mediates the acetylation of the acidic amino terminus of processed forms of beta- and gamma-actin (ACTB and ACTG, respectively).

This gene encodes a member of the N-acetyltransferase family. N-acetyltransferases modify proteins by transferring acetyl groups from acetyl CoA to the N-termini of protein substrates. The encoded protein is a cytoplasmic N-acetyltransferase with a substrate specificity for proteins with an N-terminal methionine. This gene is located in the tumor suppressor gene region on chromosome 3p21.3 and the encoded protein may play a role in cancer. Alternatively spliced transcript variants encoding multiple isoforms have been observed. This gene overlaps and is on the same strand as hyaluronoglucosaminidase 3, and some transcripts of each gene share a portion of the first exon.

  • newly identified polymorphism leads to a non-conservative amino acid change (R222W) located between the acetyltransferase and the proline-rich domains; analysis suggests no likely association between nasopharyngeal cancer and the FUS2 gene polymorphism (PMID:15036368)
  • NAT6/FUS-2 is the N-alpha acetyltransferase 80 (NAA80/NatH) acting post-translationally and specifically on processed animal actins. This NAA80 mediated actin N-terminal acetylation is crucial for actin polymerization and depolymerization, and regulates the actin cytoskeleton and cell motility. (PMID:29581253)

  • NAA80/NatH is dedicated to the post-translational N-terminal acetylation of processed actins. The structure of NAA80 reveals features like a positively charged catalytic groove perfectly suited to bind the acidic actin N-terminus. A cellular factor restricting NAA80 to processed actins is NatB, which co-translationally acetylates all cellular Met-starting N-termini with acidic amino acids at the second position.

Function. N-alpha-acetyltransferase that specifically mediates the acetylation of the acidic amino terminus of processed forms of beta- and gamma-actin (ACTB and ACTG, respectively). N-terminal acetylation of processed beta- and gamma-actin regulates actin filament depolymerization and elongation. In vivo, preferentially displays N-terminal acetyltransferase activity towards acid N-terminal sequences starting with Asp-Asp-Asp and Glu-Glu-Glu. In vitro, shows high activity towards Met-Asp-Glu-Leu and Met-Asp-Asp-Asp. May act as a tumor suppressor.

Subcellular location. Cytoplasm. Cytosol.

Tissue specificity. Strongly expressed in heart and skeletal muscle, followed by brain and pancreas, with weak expression in kidney, liver, and lung and no expression in placenta.

Disease relevance. Auroneurodental syndrome (ANDS) [MIM:620830] An autosomal recessive syndrome characterized by progressive high-frequency sensorineural hearing loss, craniofacial dysmorphism, developmental delay and mild proximal and axial muscle weakness. The disease is caused by variants affecting the gene represented in this entry.

Similarity. Belongs to the acetyltransferase family.
