KCNS3 and fetal growth restriction: Although expression of Kv1.2, Kv2.1, Kv3.1, and Kv9.3 p-Tyr increased in IUGR-hypoxia groups compared to control-hypoxia groups, only Kv1.5 α-protein levels decreased more significantly than the mRNA decreased, indicating that the Kv1.5 channel is more sensitive than other Kv channels to the role of tyrosine phosphorylation.
