Summary: Enables calcium, potassium:sodium antiporter activity; calcium-dependent protein binding activity; and calmodulin binding activity. Involved in several processes, including calcium ion transmembrane transport; cellular response to high light intensity; and cone photoresponse recovery. Acts upstream of or within positive regulation of gene expression. Located in several cellular components, including cone photoreceptor outer segment; plasma membrane; and vesicle. Is active in apical plasma membrane. Is expressed in several structures, including central nervous system; eye; stomach; testis; and thymus. Human ortholog(s) of this gene implicated in amelogenesis imperfecta hypomaturation type 2A5 and pigmentation disease. Orthologous to human SLC24A4 (solute carrier family 24 member 4).

Odor sampling strategies in mice with genetically altered olfactory responses.
Title: Odor sampling strategies in mice with genetically altered olfactory responses.
Thus, despite its relative abundance in the lens, Nckx4 does not appear to have an indispensable role in the maintenance of lens clarity.
Title: Expression of potassium-dependent sodium-calcium exchanger in the murine lens.
The authors show that NCKX4 shapes the cone photoresponse together with the cone-specific NCKX2: NCKX4 acts early to limit response amplitude, while NCKX2 acts late to further accelerate response recovery. The regulation of Ca(2+) by NCKX4 in cones is a novel mechanism that supports their ability to function as daytime photoreceptors and promotes their survival.
Title: The Na(+)/Ca(2+), K(+) exchanger NCKX4 is required for efficient cone-mediated vision.
immunostaining of the apical plasma membranes of fluorotic ameloblasts was strongly reduced or absent suggesting that trafficking of NCKX4 to the apical membrane was strongly reduced
Title: Reduced Protein Expression of the Na(+)/Ca(2+)+K(+)-Exchanger (SLC24A4) in Apical Plasma Membranes of Maturation Ameloblasts of Fluorotic Mice.
olfactory sensory neurons in NCKX4(-/-);CNGB1(DeltaCaM) mice displayed markedly reduced electro-olfactogram amplitude accompanied by alterations in other response attributes
Title: Simultaneous Loss of NCKX4 and CNG Channel Desensitization Impairs Olfactory Sensitivity.
pigment cells express robust, functional NCKX4 activity
Title: Identification and Characterization of K(+)-Dependent Na(+)-Ca(2+) Exchange Transport in Pigmented MEB4 Cells Mediated by NCKX4.
These findings highlight an essential, and to our knowledge previously unknown, role for Ca(2+) signaling in the MC4R pathway that leads to satiety, and a novel non-redundant role for NCKX4-mediated Ca(2+) extrusion in controlling MC4R signaling
Title: An essential role for the K+-dependent Na+/Ca2+-exchanger, NCKX4, in melanocortin-4-receptor-dependent satiety.
NCKX4 activity is stimulated by ATP through activation of the P2Y receptor signalling pathway.
Title: Purinergic stimulation of K+-dependent Na+/Ca2+ exchanger isoform 4 requires dual activation by PKC and CaMKII.
NCKX4 might be an important regulator of Ca(2+) transport during amelogenesis.
Title: Expression of the sodium/calcium/potassium exchanger, NCKX4, in ameloblasts.
These findings support a key role for SLC24A4 in calcium transport during enamel formation.

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.
