Also known as

Summary
NAT5 is a component of N-acetyltransferase complex B (NatB). Human NatB performs cotranslational N(alpha)-terminal acetylation of methionine residues when they are followed by asparagine (Starheim et al., 2008 [PubMed 18570629]).[supplied by OMIM, Apr 2009]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

    See identical proteins and their annotated locations for NP_852669.1

    Status: VALIDATED

    Description
    Transcript Variant: This variant (3) lacks an alternate exon compared to variant 1, which causes a frameshift. The exon combination for the transcript is supported by full-length ESTs (BG548527.1 and CD641402.1). The resulting isoform (c) is shorter and has a distinct C-terminus compared to isoform a.
