FAN1 is a a structure-selective DNA repair nuclease with 5' flap endonuclease activity, involved in the repair of interstrand DNA crosslinks [2,3]. FAN1 is the only eukaryotic protein with a VRR-NUC domain. This domain is also found in TseVs antibacterial effectors secreted by the type VI secretion system (T6SS). TseVs are evolutionary related to Holliday junction resolvases and enzymes involved in DNA interstrand crosslink repair [4].

Fan1 is involved in the processing of DNA interstrand crosslinks (ICLs) and therefore in the maintenance of genomic stability and prevention of tissue decline in multiple organs. FAN1 consists of an SAP-containing N-terminal domain, a middle tetratricopeptide repeat domain (TPR) and a C-terminal viral replication and repair nuclease domain (VRR_nuc domain, Pfam:PF08774). This entry represents the SAP subdomain, part of the N-terminal domain. It consists of four alpha-helices [1-3].

FAN1 is a DNA structure-specific nuclease involved in processing DNA interstrand crosslinks. FAN1 maintains genomic stability and prevents tissue decline in multiple organs [1-3]. It mediates cancer drug resistance in several cancer subtypes.

It maintains genomic stability and prevents tissue decline in several organs. This protein possesses preferential endonuclease activity toward 5' flap structures [1-5]. FAN1 is present in most eukaryotes and some bacterial sequences. It consists of four characterised domains: UBZ, SAP, TPR and VRR nuclease (Pfam:PF08774). However, monocellular eukaryote and bacterial homologues lack the UBZ domain [1]. The N-terminal helical domain of FAN1 can be subdivided in a winged-helix (WH) DNA-binding domain, represented in this entry, and a SAP domain (bacterial Pfam:PF18081 and eukaryotic Pfam:PF21169) [1-5].
