Gene type: protein coding
RefSeq status: VALIDATED
Organism: Mus musculus
Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Glires; Rodentia; Myomorpha; Muroidea; Muridae; Murinae; Mus; Mus
Also known as: NHA2; NHE10; nhaoc; Nhedc2; nha-oc
Summary: Predicted to enable identical protein binding activity; lithium:proton antiporter activity; and sodium:proton antiporter activity. Involved in several processes, including flagellated sperm motility; regulation of insulin secretion involved in cellular response to glucose stimulus; and sodium ion homeostasis. Acts upstream of or within positive regulation of osteoclast development. Located in several cellular components, including basolateral plasma membrane; cytoplasmic vesicle; and sperm principal piece. Is expressed in alimentary system; brain; femur; male reproductive gland or organ; and mesenteric adipose tissue. Orthologous to human SLC9B2 (solute carrier family 9 member B2).

What's a GeneRIF?

Data suggest that dietary salt elevates NHA2 expression in the nephron; NHA2 expression is localized apically to distal convoluted tubules and connecting tubules in the nephron; NHA2 expression in the nephron partially overlaps in distribution with V-type ATPase.
Title: NHA2 is expressed in distal nephron and regulated by dietary sodium.
data revealed that NHA1 and NHA2 function as a key sodium-hydrogen exchanger responsible for sperm motility after leaving the cauda epididymidis.
Title: Sodium-hydrogen exchanger NHA1 and NHA2 control sperm motility and male fertility.
Data indicate a critical role of the endosomal sodium/hydrogen exchanger NHA2 for clathrin-mediated endocytosis and insulin secretion in beta-cells.
Title: Sodium/hydrogen exchanger NHA2 is critical for insulin secretion in β-cells.
Data show evidence that NHEDC2 regulates osteoclastogenesis, an exhaustive analysis shows that Nhedc2GT/GT mice have no defect in osteoclast formation or function in vitro or in vivo.
Title: The collection of NFATc1-dependent transcripts in the osteoclast includes numerous genes non-essential to physiologic bone resorption.
These data from NHA2-deficient mice suggest that NHA2 is dispensable for osteoclast differentiation and bone resorption both in vitro and in vivo.
Title: Sodium/hydrogen exchanger NHA2 in osteoclasts: subcellular localization and role in vitro and in vivo.
NHA-oc/NHA2 displays the expected activities of a bona fide cation-proton antiporter and plays a key role(s) in normal osteoclast differentiation and function

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.
