In the neuroblastoma cells SH-SY5Y, co-IP of endogenous ANKK1 and FARP1 demonstrated their interaction under proliferative (neuroblast-like) or serum-starved conditions (0% fetal bovine serum, FBS) that induce neural differentiation (neuronal-like) (Figure 1B). Here, ANKK1 is linked to neuroblastoma.
