Summary: Predicted to enable iron ion binding activity. Predicted to be involved in several processes, including negative regulation of substrate adhesion-dependent cell spreading; positive regulation of extracellular matrix disassembly; and positive regulation of plasminogen activation. Predicted to be located in cell surface. Predicted to be active in endosome; extracellular space; and plasma membrane. Is expressed in several structures, including genitourinary system; gut; hemolymphoid system gland; integumental system; and sensory organ. Orthologous to human MELTF (melanotransferrin).

What's a GeneRIF?

melanotransferrin has a role in cell proliferation and tumorigenesis
Title: The function of melanotransferrin: a role in melanoma cell proliferation and tumorigenesis.
Iron indices, tissue levels, hematology, and serum chemistry parameters demonstrated no differences between metallototransferrin deficient and wild-type mice, suggesting MTf was not essential for iron metabolism.
Title: Role of melanotransferrin in iron metabolism: studies using targeted gene disruption in vivo.
MTf represents the first identification of a plant lectin receptor involved in cell-shape changes and the differentiation of animal cells
Title: Anti-membrane-bound transferrin-like protein antibodies induce cell-shape change and chondrocyte differentiation in the presence or absence of concanavalin A.
The distribution of MTf and its splice variants may provide clues to their possible biological roles in melanoma and other tumors.
Title: Examination of the distribution of the transferrin homologue, melanotransferrin (tumour antigen p97), in mouse and human.

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.
