Folate binding receptor, FRα (Jones et al. 2017).

FRα of Homo sapiens (P15328)
9.B.92.1.2









IZUMO1R, FolR4, JUNO of 250 aas.  Receptor for IZUMO1 present at the cell surface of oocytes (oolemma), which is essential for gamete recognition and fertilization. The IZUMO1:IZUMO1R/JUNO interaction is a necessary adhesion event between sperm and egg that is required for fertilization but is not sufficient for cell fusion. The ligand-receptor interaction probably does not act as a membrane 'fusogen' (Sabetian et al. 2014). Does not bind folate.

Riboflavin binding protein, RBP, of 242 aas and 1 N-terminal TMS.  It is believed to play a role in riboflavin transport (White and Merrill 1988; Foraker et al. 2003).

Retbindin of 229 aas and 1 N-terminal TMS. Riboflavin-binding protein that may play a role in retinal flavin transport. It is an extracellular riboflavin binding protein found in the photoreceptor/retinal pigment epithelium interface (Kelley et al. 2015).
