N-terminal His-tagged/Tag-Free

Buffer

Lyophilized from Tris/PBS-based buffer, 6% Trehalose, pH 8.0

Storage

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.

Target Background

Function

N-alpha-acetyltransferase that specifically mediates the acetylation of N-terminal residues of the transmembrane proteins, with a strong preference for N-termini facing the cytosol. Displays N-terminal acetyltransferase activity towards a range of N-terminal sequences including those starting with Met-Lys, Met-Val, Met-Ala and Met-Met. Required for normal chromosomal segregation during anaphase. May also show histone acetyltransferase activity; such results are however unclear in vivo and would require additional experimental evidences.

Gene References into Functions

Results from a study on gene expression variability markers in early-stage human embryos shows that NAA60 (NAT15) is a putative expression variability marker for the 3-day, 8-cell embryo stage. PMID:26288249
The hNaa60 protein contains an amphipathic helix following its GNAT domain that may contribute to Golgi localization of hNaa60, and the beta7-beta8 hairpin adopted different conformations in the hNaa60(1-242) and hNaa60(1-199) crystal structures. PMID:27550639

Knockdown of the N-terminal acetyltransferase Naa60 compromises Golgi ribbon integrity. PMID:26164078
The first crystal structure of the N-terminal acetyltransferase Naa60 reveals two elongated loops important for substrate-specific binding not found in other NAT structures. PMID:27320834
Naa60 is necessary for maintenance of the Golgi ribbon through its Nt-acetylation of substrate protein(s) that is/are involved in Golgi ribbon structural and/or functional organization. PMID:25732826
Naa60 is an N-terminal acetyltransferase defined as NatF. Human and Drosophila melanogaster Naa60 acetylate Met-Lys- and other Met-starting N-termini. In Drosophila cells, NAA60 knockdown induced chromosomal segregation defects. PMID:21750686
