Summary: Enables peptidase activity. Predicted to be involved in several processes, including defense response to other organism; negative regulation of hydrolase activity; and regulation of signal transduction. Predicted to act upstream of or within several processes, including iron ion homeostasis; ossification; and proteolysis. Located in cytoplasm. Is expressed in several structures, including early conceptus; epithelium; genitourinary system; immune system; and liver. Human ortholog(s) of this gene implicated in candidiasis; lung non-small cell carcinoma; and renal cell carcinoma. Orthologous to human LTF (lactotransferrin).

Lactoferrin can induce MDSCs differentiation and apoptosis, as well as upregulate TLR9 expression. TLR9 agonist or lactoferrin treatment can rescue this phenotype in the tumor metastasis mouse model. Our results suggest a protective role of lactoferrin in cancer metastasis, along with a deficiency in certain components of the innate immune system, may lead to a pro-metastatic tumor microenvironment.

LTF mRNA was undetectable in the mouse brain, even after ICH. Unlike mRNA, LTF protein increased in ICH-affected hemispheres by 6 hours, peaked at 24 to 72 hours, and remained elevated for at least a week after ICH. At the single cell level, LTF was detected in PMNs in the hematoma-affected brain at all time points after ICH. We also found elevated LTF in the plasma after ICH.

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.
