Expressed in tail. Human ortholog(s) of this gene implicated in type 2 diabetes mellitus. Is an ortholog of human IGF2BP1 (insulin like growth factor 2 mRNA binding protein 1); IGF2BP2 (insulin like growth factor 2 mRNA binding protein 2); and IGF2BP3 (insulin like growth factor 2 mRNA binding protein 3).
