Mouse models for the study of clustered protocadherins

Area of Science:

• Neuroscience
• Molecular Biology
• Genetics

Background:

• Clustered protocadherins (cPcdhs) are cell-surface molecules with diverse recognition cues.
• They are widely expressed throughout the nervous system.
• cPcdhs play significant roles in neural development.

Purpose of the Study:

• To review mouse models that illuminate the regulation and function of cPcdhs.
• To understand the molecular mechanisms governing cPcdh expression and activity.

Main Methods:

• Utilizing various mouse models targeting the cPcdh locus.
• Investigating the interplay of epigenetic marks, DNA looping, and transcription factor binding in cPcdh regulation.

Main Results:

• cPcdhs are essential for neuronal survival, dendritic and axonal branching, self-avoidance, targeting, and synapse formation.
• Expression of cPcdhs is tightly controlled by complex regulatory mechanisms.
• Mouse models have been instrumental in dissecting these regulatory networks and functional roles.

Conclusions:

• cPcdhs are critical for establishing functional neural circuits.
• Understanding cPcdh regulation provides insights into neural development and potential therapeutic targets.
• Continued study using mouse models will further unravel the complexities of cPcdh function.
