FOLR4 (Folate receptor 4; also FR4 and folate receptor dH2O and folate binding protein 3) is a 34-36kD 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, FR4hiCD25hi expression defines Treg cells, FR4loCD25+ expression pattern identifies effector memory T cells, and a FR4hiCD25- combination characterizes central memory T cells.
Mature human FOLR4 is 225aa in length (aa20-244).
It contains virtually no identifiable motifs.
There is one potential splice variant that shows a five aa substitution for (aa111-116).
Over (aa134-220) human FOLR4 shares 72% aa identity with mouse FOLR4.
