*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).
