Pricing Availability   Qty
Cat.No. 2207 - PDZ1 Domain inhibitor peptide | Tyr-Lys-cyclo(-Lys-Thr-Glu-β-Ala-)-Val | CAS No. 1315378-73-4
Description: Disrupts interaction between GluK2 and PSD-95 PDZ1 domain
Literature (8)

Biological Activity

Novel cyclic peptide that disrupts interaction between GluK2 (formerlyy GluR6) and the postsynaptic density protein 95 (PSD-95). Competes with the C-terminus of GluK2 for binding to the PDZ1 domain of PSD-95. Inhibits clustering of kainate receptors.

Addiction Poster

The key feature of drug addiction is the inability to stop using a drug despite clear evidence of harm. This poster describes the brain circuits associated with addiction, and provides an overview of the main classes of addictive drugs and the neurotransmitter systems that they target.


Epilepsy Poster

Epilepsy is a brain disease that affects 60 million people globally. More than 20 anti-seizure drugs are currently available, but these do not address the underlying causes of the condition. This poster summarizes current knowledge about the development of the condition and highlights some approaches that have disease-modifying effects in proof-of-concept studies.

Learning & Memory

Learning & Memory Poster

Recognition memory enables us to make judgements about whether or not we have encountered a particular stimulus before. This poster outlines the cellular mechanisms underlying recognition memory and its links to long-term depression, as well as the use of pharmacological intervention to assess the role of neurotransmitters in recognition memory.


Pain Poster

Peripheral sensitization is the reduction in the threshold of excitability of sensory neurons that results in an augmented response to a given external stimulus. This poster outlines the excitatory and inhibitory signaling pathways involved in modulation of peripheral sensitization. The role of ion channels, GPCRs, neurotrophins, and cytokines in sensory neurons are also described.


Parkinson's Poster

Parkinson's disease (PD) causes chronic disability and is the second most common neurodegenerative condition. This poster outlines the neurobiology of the disease, as well as highlighting current therapeutic treatments for symptomatic PD, and emerging therapeutic strategies to delay PD onset and progression.


Schizophrenia Poster

Schizophrenia is a debilitating psychiatric disorder that affects 1% of the worldwide population. This poster describes the neurobiology of Schizophrenia, as well as highlighting the genetic and environmental factors that play a fundamental role in the etiology of the disease. The current and emerging drug targets are also discussed.
