Preparation and Storage

Background: FOLR4

FOLR4 (Folate receptor 4; also FR4 and folate receptor δ and folate binding protein 3) is a 34‑36 kDa member of the folate receptor family of molecules. Based on mouse, it appears to be a marker for subsets of T cells. In particular, and in conjunction with CD25, FR4^hiCD25^hi expression defines T reg cells, FR4^loCD25⁺ expression pattern identifies effector memory T cells, and a FR4^hiCD25^- combination characterizes central memory T cells. Mature human FOLR4 is 225 amino acids (aa) in length (aa 20‑244). It contains virtually no identifiable motifs. There is one potential splice variant that shows a five aa substitution for aa 111‑116. Over aa 134‑220, human FOLR4 shares 72% aa identity with mouse FOLR4.
