Fan1 Protein is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
FAN1 Protein (FANCD2 Associated Nuclease 1) is a structure-specific nuclease involved in DNA interstrand crosslink repair and genome stability maintenance. This protein plays a critical role in maintaining genomic integrity through its participation in the Fanconi anemia (FA) pathway and related DNA repair mechanisms.

FAN1 contains several functional domains that mediate its DNA repair functions:
The structure allows FAN1 to specifically recognize and cleave branched DNA structures including fork-like and HJ-like DNA intermediates generated during DNA repair processes.
FAN1 is a key player in the FA-BRCA network of DNA damage response:
The molecular function of FAN1 involves:
FAN1 has emerged as an important genetic modifier of Huntington's disease:
