"Here, we report the interaction between RhoA and the delayed rectifier potassium channel Kv1.2."
sparser
"Since Kv1.2 is endogenously expressed in NG108-15 neuroblastoma cells ( Yokoyama et al. 1989 ), we asked whether we could detect interactions between RhoA and Kv1.2 in this native system."
sparser
"After verifying that RhoA interacts with Kv1.2, we next asked whether this interaction affects Kv1.2 physiology."

"To determine whether the interaction between Kv1.2 and RhoA is cytoplasmic or takes place at the membrane level, we performed coimmunoprecipitation experiments in a crude membrane preparation using 293 cells stably expressing Kv1.2."
sparser
"RhoA coimmunoprecipitates Kv1.2 in the membrane ( Figure 1 B), suggesting that RhoA associates with Kv1.2 in its membrane-associated, GTP-bound state."
