Disease

NAA20_HUMAN Autosomal recessive non-syndromic intellectual disability. The disease is caused by variants affecting the gene represented in this entry.

Function

NAA20_HUMAN Catalytic subunit of the NatB complex which catalyzes acetylation of the N-terminal methionine residues of peptides beginning with Met-Asp, Met-Glu, Met-Asn and Met-Gln (PubMed:34230638). Proteins with cell cycle functions are overrepresented in the pool of NatB substrates. Required for maintaining the structure and function of actomyosin fibers and for proper cellular migration.^[1] ^[2]
