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: 62 kDa. Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
FunctionPotassium channel subunit. Modulates channel activity by shifting the threshold and the half-maximal activation to more negative values.
Tissue specificityDetected in lung, liver, kidney, pancreas, spleen, thymus, prostate, testis, ovary and colon.
Involvement in diseaseDefects in KCNV2 are the cause of cone dystrophy retinal type 3B (RCD3B) [MIM:610356]; also called cone dystrophy with night blindness and supernormal rod responses KCNV2-related. RCD3B is a rare form of cone dystrophy associated with supernormal rod responses. The disorder is characterized by reduced visual acuity, photoaversion, night blindness, and abnormal color vision. At an early age, the retina shows subtle depigmentation at the macula and, later, more obvious areas of atrophy.
Sequence similaritiesBelongs to the potassium channel family. V (TC 1.A.1.2) subfamily. Kv8.2/KCNV2 sub-subfamily.
DomainThe segment S4 is probably the voltage-sensor and is characterized by a series of positively charged amino acids at every third position.
Cellular localizationCell membrane. Has to be associated with KCNB1 or possibly another partner to get inserted in the plasma membrane. Remains intracellular in the absence of KCNB1.
