KCNN2 codes for an integral membrane protein that forms a part of a voltage-independent calcium-activated channel. KCNN2 deletions have been implicated in behavioural defects. Rabbit Anti-KCNN2 antibody recognizes human, mouse, rat, bovine, pig, chicken, canine, and zebrafish KCNN2.
Immunogen
Synthetic peptide directed towards the C terminal region of human KCNN2
Application
Rabbit Anti-KCNN2 antibody is suitable for western blot applications at a concentration of 1.25 μg/ml.
Biochem/physiol Actions
Action potentials in vertebrate neurons are followed by an afterhyperpolarization (AHP) that may persist for several seconds and may have profound consequences for the firing pattern of the neuron. Each component of the AHP is kinetically distinct and is mediated by different calcium-activated potassium channels. The protein encoded by KCNN2 is activated before membrane hyperpolarization and is thought to regulate neuronal excitability by contributing to the slow component of synaptic AHP. The encoded protein is an integral membrane protein that forms a voltage-independent calcium-activated channel with three other calmodulin-binding subunits. KCNN2 is a member of the KCNN family of potassium channel genes.

Enhanced intrinsic neuronal excitability of hippocampal pyramidal neurons via reductions in the postburst afterhyperpolarization (AHP) has been hypothesized to be a biomarker of successful learning. This is supported by considerable evidence that pharmacologic enhancement of neuronal excitability facilitates learning. However
Small-conductance Ca(2+)-activated potassium (SK) channels are heteromeric complexes of SK alpha-subunits and calmodulin that modulate membrane excitability, are responsible for part of the after-hyperpolarization (AHP) following action potentials, and thus control the firing patterns and excitability of most central neurons.
