Summary: Acts upstream of or within muscle cell development; regulation of protein glycosylation; and vasculogenesis. Predicted to be active in Golgi membrane. Is expressed in several structures, including brain; cloacal chamber; fin bud; myotome; and shield. Human ortholog(s) of this gene implicated in dilated cardiomyopathy (multiple) and muscular dystrophy (multiple). Orthologous to human FKTN (fukutin).

What's a GeneRIF?

Fukutin and FKRP have functions that affect ocular development in zebrafish independently of dystroglycan.
Title: Abnormal vascular development in zebrafish models for fukutin and FKRP deficiency.
Muscle pathology in embryos lacking Fukutin or FKRP is different from loss of dystroglycan; knockdown of Fukutin or FKRP leads to a notochord defect and a perturbation of laminin expression before muscle degeneration.
Title: Zebrafish Fukutin family proteins link the unfolded protein response with dystroglycanopathies.

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.
