  • IHC image of CSB-PA012013LA01HU diluted at 1:200 and staining in paraffin-embedded human pancreatic cancer performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a biotinylated secondary antibody and visualized using an HRP conjugated SP system.

  • Immunofluorescence staining of HepG2 cells with CSB-PA012013LA01HU at 1:66, counter-stained with DAPI. The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4°C. The secondary antibody was Alexa Fluor 488-congugated AffiniPure Goat Anti-Rabbit IgG(H+L).

Target Background

Function
Cytoplasmic potassium channel subunit that modulates the characteristics of the channel-forming alpha-subunits. Modulates action potentials via its effect on the pore-forming alpha subunits. Promotes expression of the pore-forming alpha subunits at the cell membrane, and thereby increases channel activity. Mediates closure of delayed rectifier potassium channels by physically obstructing the pore via its N-terminal domain and increases the speed of channel closure for other family members. Promotes the closure of KCNA1, KCNA2 and KCNA5 channels. Accelerates KCNA4 channel closure. Accelerates the closure of heteromeric channels formed by KCNA1 and KCNA4. Accelerates the closure of heteromeric channels formed by KCNA2, KCNA5 and KCNA6. Isoform KvB1.2 has no effect on KCNA1, KCNA2 or KCNB1. Enhances KCNB1 and KCNB2 channel activity. Binds NADPH; this is required for efficient down-regulation of potassium channel activity. Has NADPH-dependent aldoketoreductase activity. Oxidation of the bound NADPH strongly decreases N-type inactivation of potassium channel activity.
Gene References into Functions
  1. Genetic variations of KCNAB1 and CRYAA are associated with age-related nuclear cataract. PMID: 24951543
  2. Protein kinase C inhibition results in a Kv 1.5 and Kv beta 1.3 pharmacology closer to Kv 1.5 channels PMID: 24946104
  3. These results support KCNAB1 as a susceptibility gene for lateral temporal epilepsy , in agreement with previous studies showing that this gene may alter susceptibility to focal epilepsy. PMID: 21333500
  4. Double-mutant cycle analysis indicates that R5 of Kvbeta1.3 interacts with A501 and T480 of Kv1.5, residues located deep within the pore of the channel. PMID: 18987637
