Summary: Predicted to enable metal ion binding activity. Acts upstream of or within hemoglobin biosynthetic process; iron ion transport; and response to bacterium. Predicted to be located in extracellular region. Predicted to be active in endosome; extracellular space; and plasma membrane. Is expressed in several structures, including ball; liver; ovary; renal system; and yolk syncytial layer. Human ortholog(s) of this gene implicated in several diseases, including anemia (multiple); atransferrinemia; carcinoma (multiple); glucose metabolism disease (multiple); and restless legs syndrome. Orthologous to human LTF (lactotransferrin) and TF (transferrin). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

The zebrafish hypochromic anemia mutant, gavi, exhibits transferrin deficiency due to mutations in transferrin-a.Transferrin-a plays a critical role both in iron transport & in regulating hepcidin expression in zebrafish embryos.
Title: Transferrin-a modulates hepcidin expression in zebrafish embryos.
transferrin mRNAs in zebrafish were first expressed at approximately 7 hours postfertilization (hpf) in the yolk syncytial layer and later in the liver rudiment (48 hpf) and in the esophagus transiently (72-96 hpf)
Title: Expression analyses of zebrafish transferrin, ifabp, and elastaseB mRNAs as differentiation markers for the three major endodermal organs: liver, intestine, and exocrine pancreas.

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.
