Protein attributes

Sequence length	178 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	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. 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. Ref.7 Ref.10
Catalytic activity	Acetyl-CoA + peptide = N(alpha)-acetylpeptide + CoA.
Subunit structure	Component of the N-terminal acetyltransferase B (NatB) complex which is composed of NAA20 and NAA25.
Subcellular location	Cytoplasm. Nucleus Ref.7.
Sequence similarities	Belongs to the acetyltransferase family. ARD1 subfamily. Contains 1 N-acetyltransferase domain.
Sequence caution	The sequence BG548527 differs from that shown. Reason: Frameshift at position 111.
