The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 1 µg/ml. Predicted molecular weight: 97 kDa. Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
Probably important in the regulation of neuronal excitability. Associates with KCNQ2 or KCNQ5 to form a potassium channel with essentially identical properties to the channel underlying the native M-current, a slowly activating and deactivating potassium conductance which plays a critical role in determining the subthreshold electrical excitability of neurons as well as the responsiveness to synaptic inputs.
Predominantly expressed in brain.
Involvement in disease
Defects in KCNQ3 are the cause of benign neonatal epilepsy type 2 (EBN2) [MIM:121201]. Benign neonatal epilepsy is characterized by clusters of seizures occurring in the first days of life. Most patients have spontaneous remission by 12 months of age and show normal psychomotor development. The disorder is distinguished from benign familial infantile seizures by an earlier age at onset.
Belongs to the potassium channel family. KQT (TC 1.A.1.15) subfamily. Kv7.3/KCNQ3 sub-subfamily.
The segment S4 is probably the voltage-sensor and is characterized by a series of positively charged amino acids at every third position.
