N-alpha-acetyltransferase 20 (NAA20)

Catalytic subunit of the NatB complex which catalyzes acetylation of the N-terminal methionine residues of peptides starting with Met-Asp, Met-Glu, Met-Asn and Met-Gln. Proteins with cell cycle functions are overrepresented at the pool of NatB substrates.

Required for maintaining the structure and function of actomyosin fibers and for proper cellular migration. .
