Calretinin neurons express the calcium-binding protein calretinin (CR, encoded by CALB2), which serves as a cytoplasmic calcium buffer. These neurons are distributed throughout the brain and are particularly abundant in specific interneuron populations, where they play important roles in network oscillation and information processing.

Overview
Mermaid diagram (expand to render)
Calretinin (CR, 29 kDa) is a cytosolic calcium-binding protein belonging to the EF-hand protein family. It is expressed in specific neuronal populations throughout the brain, particularly in diverse interneuron subtypes. Calretinin neurons represent a major class of inhibitory neurons that contribute to gamma oscillations, sensory processing, and cortical circuit function [1](https://pubmed.ncbi.nlm.nih.gov/10521556/).
Molecular Biology
Calretinin Structure
Gene: CALB2 (calretinin 2)
Protein: 271 amino acids, 6 EF-hand domains
Calcium binding: High affinity (KD ~10^-7 M), slow kinetics
The study of Calretinin Neurons has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
