Description

The FOLR1 protein is a member of the folate receptor family. Folate receptors are cell surface proteins that bind folate (vitamin B9) and transport it into cells. FOLR1 Protein, Rat (HEK293, His) is the recombinant rat-derived FOLR1 protein, expressed by HEK293 , with C-His labeled tag.

Background

FOLR1 Protein is a member of the folate receptor family. Folate receptors are cell surface proteins that bind and transport folate (vitamin B9) into cells. FOLR1 is widely expressed in various tissues, including the placenta, kidney, lung, and intestine. It plays a crucial role in folate metabolism by mediating the cellular uptake of folate. FOLR1 is particularly important during pregnancy, as it facilitates the transport of folate across the placenta to support fetal development. In addition to its role in folate transport, FOLR1 has been implicated in other cellular processes, including cell adhesion, migration, and signaling. It is also being investigated as a potential target for cancer therapy, as FOLR1 expression is frequently upregulated in several types of cancer cells, making it a promising candidate for targeted drug delivery.
