Summary: Enables phosphotransferase activity, for other substituted phosphate groups. Acts upstream of or within several processes, including basement membrane organization; brain development; and skeletal muscle fiber differentiation. Located in Golgi membrane. Is expressed in several structures, including central nervous system; future brain; genitourinary system; sensory organ; and spinal ganglion. Used to study Fukuyama congenital muscular dystrophy and muscular dystrophy-dystroglycanopathy type B1. Human ortholog(s) of this gene implicated in dilated cardiomyopathy (multiple) and muscular dystrophy (multiple). Orthologous to human FKTN (fukutin).

Mitochondrial dysfunction in skeletal muscle of fukutin-deficient mice is resistant to exercise- and 5-aminoimidazole-4-carboxamide ribonucleotide-induced rescue.

Study shows molecular pathogenesis of muscular dystrophy-associated cardiomyopathy in mice lacking the Fktn gene. Although cardiac Fktn elimination markedly reduced alpha-dystroglycan glycosylation and dystrophin-glycoprotein complex proteins in sarcolemma at all developmental stages, cardiac dysfunction was observed only in later adulthood, suggesting that membrane fragility is not the sole etiology of cardiac dysfunc...

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.
