Summary: The protein encoded by this gene belongs to the family of P-type cation transport ATPases, and to the subfamily of Na+/K+ -ATPases. Na+/K+ -ATPase is an integral membrane protein responsible for establishing and maintaining the electrochemical gradients of Na and K ions across the plasma membrane. These gradients are essential for osmoregulation, for sodium-coupled transport of a variety of organic and inorganic molecules, and for electrical excitability of nerve and muscle. This enzyme is composed of two subunits, a large catalytic subunit (alpha) and a smaller glycoprotein subunit (beta). The catalytic subunit of Na+/K+ -ATPase is encoded by multiple genes. This gene encodes an alpha 4 subunit. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2008]

Human ATP1A4 enhances mouse sperm motility and hyperactivity during capacitation.
Title: Role of human Na,K-ATPase alpha 4 in sperm function, derived from studies in transgenic mice.
Human Na,K-ATPase alpha 4 isoform is a sperm-specific protein localized to the flagellum, suggesting a role for human Na,K-ATPase alpha 4 isoform in human sperm physiology.
Title: The human Na,K-ATPase alpha 4 isoform is a ouabain-sensitive alpha isoform that is expressed in sperm.
These results constitute the first demonstration of the transcriptional control of ATP1A4 gene expression by cAMP and by CREMtau, a transcription factor essential for male germ cell gene expression.
Title: The transcription factor CREMtau and cAMP regulate promoter activity of the Na,K-ATPase alpha4 isoform.

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.
