FANCD2

FANCD2

A gene on chromosome 3p26 that encodes a protein of the Fanconi anaemia complementation group (here, complementation group D2), which co-locates with other proteins—e.g., BRCA1 and BRCA2—and is involved in homology-directed DNA repair.

The researchers used a mouse model of FA that lacks Fancd2, a key protein in the FA pathway.

Most FA patients harbour homozygous or double heterozygous mutations in the FANCA (60-65%), FANCC (10-15%), FANCG (~10%) or FANCD2 (3-6%) genes, while the minority of FA patients are characterised by mutations distributed in the remaining 12 FANC genes (3).

The milestone of DNA strand exchange is RAD51 protein which is closely related to other tumour suppressor genes such as TP53, ATM, BRCA1, BLM, and FANCD2. Preclinical studies showed that BRCA2 disruptions sensitize mice embryos to ionising radiation [30], which was previously observed in RAD51 knockout mice embryos [31].
Similar studies have confirmed the activation of NBN [16] and added observations showing activation of three other proteins involved in DNA repair, RPA2 [16], FANCD2, and FANCI [20].
The FA pathway is regulated by ubiquitin, in a cycle of monoubiquitination and deubiquitination of FANCD2. Despite considerable advances in our understanding of the genetics of the pathway, there is strikingly little known on a mechanistic and chemical level concerning how the ubiquitin signal is assembled, recognised and disassembled.

HCC with recurrence exhibited enrichment of upregulated genes mapping to signaling or disease pathways associated with cell cycle regulators (CDKN2B, E2F2, E2F5, GNL3, HDAC2, MDM2, MYC, and PA2G4), including the genes that encode the proteins that control molecular mechanisms of cancer (FANCD2, FZD3, PLCB1, and PMAIP1).
ATM-dependent phosphorylation of BRCA1, NBS1 and two additional players in the NBS1 branch of the pathway the SMC1, a chromosomal structural maintenance protein and FANCD2, a Fanconi anemia complementation group D2 protein, both are needed for an intact intra-S phase checkpoint (Shiloh et al., 2003; Andrea et al., 2003).
Scientists had shown previously that DNA repair was much less efficient when FANCI and FANCD2 lack the single ubiquitin.
