Protein Domain : Protein SODIUM POTASSIUM ROOT DEFECTIVE 1-3/ATX1 IPR044526

Type	Family
Description	This entry represents a group of heavy metal-associated plant proteins, including Protein SODIUM POTASSIUM ROOT DEFECTIVE 1/2/3 (NAKR1/2/3) from Arabidopsis. NAKR1, also known as NPCC6, is necessary for phloem function and root meristem maintenance [ ]. It also promotes flowering through mediating FT (FLOWERING LOCUS T) translocation from leaves to shoot apices []. It also plays an important role in the regulation of FT expression under long-day conditions []. NaKR3 is involved in the salt stress response [ ].This family also includes ATX1 (also known as copper chaperone CCH) from Arabidopsis, which shows low sequence similarities with NAKR3 [ ]. It plays an important role in copper homeostasis by conferring tolerance to excess of copper and subclinical copper deficiency during vegetative stage [].
