Fanconi anemia, complementation group E protein is a protein that in humans is encoded by the FANCE gene. [5] [6] [7] The Fanconi anemia complementation group (FANC) currently includes FANCA, FANCB, FANCC, FANCD1 (also called BRCA2), FANCD2, FANCE, FANCF, FANCG, and FANCL. Fanconi anemia is a genetically heterogeneous recessive disorder characterized by cytogenetic instability, hypersensitivity to DNA cross-linking agents, increased chromosomal breakage, and defective DNA repair. The members of the Fanconi anemia complementation group do not share sequence similarity; they are related by their assembly into a common nuclear protein complex. This gene encodes the protein for complementation groufcrp E. [7]
A nuclear complex containing FANCE protein (as well as FANCC, FANCF and FANCG) is essential for the activation of the FANCD2 protein to the mono-ubiquitinated isoform. [8] In normal, non-mutant cells, FANCD2 is mono-ubiquinated in response to DNA damage. FANCE together with FANCC acts as the substrate adapter for this reaction [9] Activated FANCD2 protein co-localizes with BRCA1 (breast cancer susceptibility protein) at ionizing radiation-induced foci and in synaptonemal complexes of meiotic chromosomes. Activated FANCD2 protein may function prior to the initiation of meiotic recombination, perhaps to prepare chromosomes for synapses, or to regulate subsequent recombination events. [8]
FANCE is stated to have been expressed in 151 organs with the highest level in female gonads. [10]
The location of the gene is in 6p21.31, where p is the short arm of chromosome 6 at position 21.31 [11]
The location at molecular level is in base pairs 35,452,339 to 35,467,106 on chromosome 6 (Homo sapiens Annotation Release 109, GRCh38.p12) [11]
The main complex of FA contains a nuclear multi-subunit complex of notably 8 FA proteins. [12] This adds a single ubiquitin chain to the FANCD2 following DNA damage or duplicative pressure. [13]
For the collection of FANCC, FANCE is important in the nucleus and gathering of the core complex. Some characteristics of FANCE are that it can set itself up with ubiquitinated FANCD2, BRCA2 and constructed nuclear foci. Also, as it is the only member showing direct union with FANCD2 and gives the needed links between FA core complex and FANCD2. [14]
The structure of FANCE has an epitope on its surface that is found to be important for its binding with FANCD2. The existence of recurrent helical motif was not clear when analysis of amino acids was done.
It consists of 13 α-helices, 1 310-helix and no β-strand. Long shaped, non-globular shape and 70 Å n size. Width of 30 Å and thickness 20 Å. The protein folds continuously in right-handed manner from N- to C- terminal. Identifying it is easy because of its helices at the end of C-end. [14]
It restores DNA cross-links and is needed for nuclear accumulation of FANCC, delivering a critical bridge between FA complex and FANCD2. [15]
FANCE-deficient mice exhibit a reduced number of oocytes and disruption of prophase I of meiosis [16] indicating that FANCE has an essential role in meiosis.
FANCE has been shown to interact with:
Fanconi anemia (FA) is a rare, autosomal recessive, genetic disease resulting in impaired response to DNA damage in the FA/BRCA pathway. Although it is a very rare disorder, study of this and other bone marrow failure syndromes has improved scientific understanding of the mechanisms of normal bone marrow function and development of cancer. Among those affected, the majority develop cancer, most often acute myelogenous leukemia (AML), MDS, and liver tumors. 90% develop aplastic anemia by age 40. About 60–75% have congenital defects, commonly short stature, abnormalities of the skin, arms, head, eyes, kidneys, and ears, and developmental disabilities. Around 75% have some form of endocrine problem, with varying degrees of severity. 60% of FA is FANC-A, 16q24.3, which has later onset bone marrow failure.
BRCA2 and BRCA2 are human genes and their protein products, respectively. The official symbol and the official name are maintained by the HUGO Gene Nomenclature Committee. One alternative symbol, FANCD1, recognizes its association with the FANC protein complex. Orthologs, styled Brca2 and Brca2, are common in other vertebrate species. BRCA2 is a human tumor suppressor gene, found in all humans; its protein, also called by the synonym breast cancer type 2 susceptibility protein, is responsible for repairing DNA.
Glutathione S-transferase P is an enzyme that in humans is encoded by the GSTP1 gene.
Fanconi anemia group C protein is a protein that in humans is encoded by the FANCC gene. This protein delays the onset of apoptosis and promotes homologous recombination repair of damaged DNA. Mutations in this gene result in Fanconi anemia, a human rare disorder characterized by cancer susceptibility and cellular sensitivity to DNA crosslinks and other damages.
Fanconi anaemia, complementation group A, also known as FAA, FACA and FANCA, is a protein which in humans is encoded by the FANCA gene. It belongs to the Fanconi anaemia complementation group (FANC) family of genes of which 12 complementation groups are currently recognized and is hypothesised to operate as a post-replication repair or a cell cycle checkpoint. FANCA proteins are involved in inter-strand DNA cross-link repair and in the maintenance of normal chromosome stability that regulates the differentiation of haematopoietic stem cells into mature blood cells.
Fanconi anemia group D2 protein is a protein that in humans is encoded by the FANCD2 gene. The Fanconi anemia complementation group (FANC) currently includes FANCA, FANCB, FANCC, FANCD1, FANCD2, FANCE, FANCF, FANCG, FANCI, FANCJ, FANCL, FANCM, FANCN and FANCO.
Fanconi anemia group G protein is a protein that in humans is encoded by the FANCG gene.
DNA repair protein XRCC2 is a protein that in humans is encoded by the XRCC2 gene.
Fanconi anemia group F protein is a protein that in humans is encoded by the FANCF gene.
E3 ubiquitin-protein ligase FANCL is an enzyme that in humans is encoded by the FANCL gene.
Fanconi anemia group B protein is a protein that in humans is encoded by the FANCB gene.
Fanconi anemia, complementation group I (FANCI) also known as KIAA1794, is a protein which in humans is encoded by the FANCI gene. Mutations in the FANCI gene are known to cause Fanconi anemia.
T-complex protein 1 subunit gamma is a protein that in humans is encoded by the CCT3 gene.
Zinc finger protein 24 is a protein that in humans is encoded by the ZNF24 gene.
Partner and localizer of BRCA2, also known as PALB2 or FANCN, is a protein which in humans is encoded by the PALB2 gene.
Zinc finger and BTB domain-containing protein 32 is a protein that in humans is encoded by the 1960 bp ZBTB32 gene. The 52 kDa protein is a transcriptional repressor and the gene is expressed in T and B cells upon activation, but also significantly in testis cells. It is a member of the Poxviruses and Zinc-finger (POZ) and Krüppel (POK) family of proteins, and was identified in multiple screens involving either immune cell tumorigenesis or immune cell development.
Ubiquitin-specific protease 14 is an enzyme that in humans is encoded by the USP14 gene.
Fanconi anemia, complementation group M, also known as FANCM is a human gene. It is an emerging target in cancer therapy, in particular cancers with specific genetic deficiencies.
FANC proteins are a network of at least 15 proteins that are associated with a cell process known as the Fanconi anemia.
