Product Specifications

Background

Sodium channel β-subunit 4, also known as SCN4B or Naβ4, is a protein that in humans is encoded by the SCN4B gene. The protein encoded by this gene is one of several sodium channel beta subunits. These subunits interact with voltage-gated alpha subunits to change sodium channel kinetics. The encoded transmembrane protein forms interchain disulfide bonds with SCN2A. Defects in this gene are a cause of long QT syndrome type 10 (LQT10) . Three protein-coding and one non-coding transcript variant have been found for this gene.

Synonyms

Sodium channel subunit beta-4; SCN4B

Gene Name

SCN4B

Gene ID

6330

UniProt

Q8IWT1

Host

Rabbit

Reactivity

Human, Mouse, Rat

Cross Reactivity

No cross-reactivity with other proteins.

Immunogen

A synthetic peptide corresponding to a sequence in the middle region of human SCN4B, which shares 72.7% amino acid (aa) sequence identity with both mouse and rat SCN4B.

Clonality

Polyclonal

Tissue Specificity

Expressed at a high level in dorsal root ganglia, at a lower level in brain, spinal cord, skeletal muscle and heart. Expressed in the atrium.

Applications

Flow Cytometry, IHC, IHC-F, ICC, WB

Field of Research

Neural Signal Transduction, Neurology Process, Neuroscience

Purification

Immunogen affinity purified.

Concentration

Adding 0.2 ml of distilled water will yield a concentration of 500 μg/ml.

Form

Lyophilized

Reconstitution

Add 0.2ml of distilled water will yield a concentration of 500ug/ml.

Function

Modulates channel gating kinetics. Causes negative shifts in the voltage dependence of activation of certain alpha sodium channels, but does not affect the voltage dependence of inactivation. Modulates the susceptibility of the sodium channel to inhibition by toxic peptides from spider, scorpion, wasp and sea anemone venom.
