Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Kappa Opioid Receptor antibody (AB113533)

IHC image of Kappa Opioid Receptor staining in Human normal placenta formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab113533, 5μg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

ab113533 stained SKNSH cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody ab113533 at 5μg/ml overnight at +4°C. The secondary antibody (green) was DyLight® 488 goat anti- rabbit (ab96899) IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43μM.

Western blot - Anti-Kappa Opioid Receptor antibody (AB113533)

This blot was produced using a 4-12% Bis-tris gel under the MOPS buffer system. The gel was run at 200V for 50 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 2% Bovine Serum Albumin before being incubated with ab113533 overnight at 4°C. Antibody binding was detected using an anti-rabbit antibody conjugated to HRP, and visualised using ECL development solution ab133406.

The Kappa Opioid Receptor also known as KOR or kappa receptors is a type of opioid receptor that plays an important role in the nervous system. It is a protein with an approximate mass of 43 kDa. This receptor mainly expresses in the human brain especially in regions involved in pain and stress responses such as the hypothalamus and thalamus. Kappa receptors are involved in modulating neurotransmitter release and can affect synaptic transmission.
Biological function summary

Kappa opioid receptors mediate pain perception mood regulation and stress response. They form part of a larger receptor family the G-protein coupled receptors (GPCRs) which are critical in cellular signaling. Activation of these receptors can produce analgesic effects differing from other opioid receptors due to their unique mechanism of action. Kappa receptors interact with endogenous ligands called dynorphins which are peptide neurotransmitters involved in natural pain relief processes.

Pathways

Kappa opioid receptors are integral to the dopaminergic and serotonergic pathways. In the dopaminergic pathway kappa receptors reduce dopamine release influencing the reward system and potentially affecting addiction behaviors. In the serotonergic pathway they modulate serotonin levels connecting to mood and anxiety regulation. These pathways also involve proteins like the mu-opioid receptor and delta-opioid receptor which along with kappa receptors form a complex regulatory network.

Kappa opioid receptors have been linked to depression and drug addiction. In depression dysfunctional kappa receptor activity may disrupt mood regulation contributing to depressive symptoms. The associated protein dynorphin plays a role in this condition by interacting with kappa receptors. In drug addiction these receptors influence the brain's reward circuits impacting addiction severity through altered dopamine signaling. Understanding kappa receptors can offer insights into new therapeutic approaches for these conditions.

Target data

G-protein coupled opioid receptor that functions as a receptor for endogenous alpha-neoendorphins and dynorphins, but has low affinity for beta-endorphins. Also functions as a receptor for various synthetic opioids and for the psychoactive diterpene salvinorin A. Ligand binding causes a conformation change that triggers signaling via guanine nucleotide-binding proteins (G proteins) and modulates the activity of down-stream effectors, such as adenylate cyclase. Signaling leads to the inhibition of adenylate cyclase activity. Inhibits neurotransmitter release by reducing calcium ion currents and increasing potassium ion conductance. Plays a role in the perception of pain. Plays a role in mediating reduced physical activity upon treatment with synthetic opioids. Plays a role in the regulation of salivation in response to synthetic opioids. May play a role in arousal and regulation of autonomic and neuroendocrine functions.
