Overview
Mermaid diagram (expand to render)
PAX6 is a transcription factor containing a paired domain and a homeodomain. It is a master regulatory gene essential for embryonic development, particularly of the eye, brain, olfactory system, and pancreas. PAX6 regulates gene expression by binding to specific DNA sequences through its DNA-binding domains.
Structure
PAX6 contains multiple functional domains:
Paired Domain (PD): N-terminal 128 aa that binds specific DNA sequences (P6 and P6' sites)
Homeodomain (HD): C-terminal helix-turn-helix motif for DNA binding
Linker Region: Connects the two DNA-binding domains
Transactivation Domain: C-terminal region that interacts with transcriptional co-activators
Proline-Serine-Threonine (PST) Rich Region: Involved in protein-protein interactions
Alternative splicing generates multiple isoforms with different DNA-binding specificities.
Small Molecule Modulators: Targeting PAX6 expression
Cell Replacement Therapy: Using PAX6 to generate [neurons](/entities/neurons)
