[edit] Physiological function

At2g01031.1/Function NADK3 (At1g78590) is a NAD(H) kinase with a strong preference for NADH over NAD+. NAD(H) kinases phosphorylate NAD(H) with ATP (other phosphoryl donors are not used preferentially) to form NADP(H). Phosphorylation of NAD(H) is the sole known means of generating NADP(H) de novo.

[edit] Subcellular localization

At2g01031.1/Localization

NADK3-GFP has been shown by in vivo transient expression to be localized to the cytosol, confirmed by immunoblotting.

[edit] Biophysical properties

The gene model At2g01031.1 has 249 amino-acid residues and a molecular weight Mw = 29.133 kDa.

The protein is relatively neutral; at the physiological pH 7.4, its net charge is -0.11, or -0.000 per residue. NADK3-GFP has been shown by in vivo transient expression to be localized to the cytosol, confirmed by immunoblotting.

[edit] Protein interactions

At2g01031.1/Interactions This protein does not interact with calmodulin in the presence or absence of calcium or EGTA. NADK3 has been reported to be phosphorylated in vitro by AtMAPK4. NADK3 forms a homodimer.

[edit] Domain structure

The gene model At2g01031.1 has no known domains. NADK3 contains the conserved NAD(H) kinase domain, GSTAAMQSAGG for binding NAD and the upstream GGDGT ATP-binding domain.
