Summary: Predicted to enable protein-macromolecule adaptor activity. Acts upstream of or within several processes, including intracellular monoatomic cation homeostasis; regulation of axon diameter; and skeletal muscle fiber development. Is active in plasma membrane. Is expressed in genitourinary system; gonadal fat pad; gut; liver; and mammary gland. Human ortholog(s) of this gene implicated in McLeod syndrome and hematopoietic system disease. Orthologous to human XK (X-linked Kx blood group antigen, Kell and VPS13A binding protein). [provided by Alliance of Genome Resources, Dec 2024]
Expression: Broad expression in liver E14.5 (RPKM 13.7), liver E14 (RPKM 12.9) and 22 other tissues See more

What's a GeneRIF?

Impaired XK recycling for importing manganese underlies striatal vulnerability in Huntington's disease.
Title: Impaired XK recycling for importing manganese underlies striatal vulnerability in Huntington's disease.
A hemizygous single base-pair frameshift deletion at exon 1 in the XK gene was found in a patient with McLeod syndrome.
Title: Novel single base-pair deletion in exon 1 of XK gene leading to McLeod syndrome with chorea, muscle wasting, peripheral neuropathy, acanthocytosis and haemolysis.
Absence of Xk was accompanied by changes in erythrocyte K(+), Mg(2+), Na(+) & Ca(2+) transport associated with changes in mean cellular volume & corpuscular hemoglobin concentration mean. Xk deletion blocked Na/Mg exchanger activity.
Title: Ablation of the Kell/Xk complex alters erythrocyte divalent cation homeostasis.

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.
