UIMC1
BRCA1-A complex subunit RAP80 is a protein that in humans is encoded by the ''UIMC1'' gene. Repair of DNA damage RAP80, the protein product of the UIMC1 gene, is a core component of the deubiquitin complex BRCA1-A.Rabl J.

PMID: 33142801; PMCID: PMC7692841 Other core components of the BRCA1-A complex are the BRCC36 protein (BRCC3 gene), BRE protein (BRE (gene)), and MERIT40 protein (BABAM1 gene).

BRE (gene)
BRCA1-A complex subunit BRE is a protein that in humans is encoded by the ''BRE'' gene. Repair of DNA damage BRE, the protein product of the BRE (gene), is a core component of the deubiquitin complex BRCA1-A. Other core components of the BRCA1-A complex are the BRCC36 protein (BRCC3 gene), MERIT40 protein (BABAM1 gene), and RAP80 protein ( UIMC1 gene). BRCA1, as distinct from BRCA1-A, is employed in the repair of chromosomal damage with an important role in the error-free homologous recombinational (HR) repair of DNA double-strand breaks. Sequestration of BRCA1 away from the DNA damage site suppresses homologous recombination and redirects the cell in the direction of repair by the process of non-homologous end joining (NHEJ). The role of BRCA1-A appears to be to bind BRCA1 with high affinity and withdraw it away from the site of DNA damage to the periphery where it remains sequestered, thus promoting NHEJ in preference to HR. Protein-protein interactions BRE (gene) has b ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

BRCA1-A complex subunit MERIT40 is a protein that in humans is encoded by the ''BABAM1'' gene. Interactions BABAM1 has been shown to Protein-protein interaction, interact with BRE (gene), BRE. Repair of DNA damage MERIT40, the protein product of the BABAM1 gene, is a core component of the deubiquitin complex BRCA1-A.

Protein
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, responding to stimuli, providing structure to cells and organisms, and transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the nucleotide sequence of their genes, and which usually results in protein folding into a specific 3D structure that determines its activity. A linear chain of amino acid residues is called a polypeptide. A protein contains at least one long polypeptide. Short polypeptides, containing less than 20–30 residues, are rarely considered to be proteins and are commonly called peptides. The individual amino acid residues are bonded together by peptide bonds and adjacent amino acid residues. The sequence of amino acid residue ...

Gene
In biology, the word gene (from , ; "...Wilhelm Johannsen coined the word gene to describe the Mendelian units of heredity..." meaning ''generation'' or ''birth'' or ''gender'') can have several different meanings. The Mendelian gene is a basic unit of heredity and the molecular gene is a sequence of nucleotides in DNA that is transcribed to produce a functional RNA. There are two types of molecular genes: protein-coding genes and noncoding genes. During gene expression, the DNA is first copied into RNA. The RNA can be directly functional or be the intermediate template for a protein that performs a function. The transmission of genes to an organism's offspring is the basis of the inheritance of phenotypic traits. These genes make up different DNA sequences called genotypes. Genotypes along with environmental and developmental factors determine what the phenotypes will be. Most biological traits are under the influence of polygenes (many different genes) as well as gen ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

BRCC3
Lys-63-specific deubiquitinase BRCC36 is an enzyme that in humans is encoded by the ''BRCC3'' gene. Function This gene encodes a subunit of the BRCA1-BRCA2-containing complex (BRCC), which is an E3 ubiquitin ligase. This protein is also thought to be involved in the cellular response to ionizing radiation and progression through the G2/M checkpoint. Alternative splicing results in multiple transcript variants. Repair of DNA damage BRCC36, the protein product of the ''BRCC3'' gene, is a deubiquitinating enzyme and a core component of the deubiquitin complex BRCA1-A.Rabl J. BRCA1-A and BRISC: Multifunctional Molecular Machines for Ubiquitin Signaling. Biomolecules. 2020 Oct 31;10(11):1503. doi: 10.3390/biom10111503.

BRCA1
Breast cancer type 1 susceptibility protein is a protein that in humans is encoded by the ''BRCA1'' () gene. Orthologs are common in other vertebrate species, whereas invertebrate genomes may encode a more distantly related gene. ''BRCA1'' is a human tumor suppressor gene (also known as a caretaker gene) and is responsible for repairing DNA. ''BRCA1'' and '' BRCA2'' are unrelated proteins, but both are normally expressed in the cells of breast and other tissue, where they help repair damaged DNA, or destroy cells if DNA cannot be repaired. They are involved in the repair of chromosomal damage with an important role in the error-free repair of DNA double-strand breaks. If ''BRCA1'' or ''BRCA2'' itself is damaged by a BRCA mutation, damaged DNA is not repaired properly, and this increases the risk for breast cancer. ''BRCA1'' and ''BRCA2'' have been described as "breast cancer susceptibility genes" and "breast cancer susceptibility proteins". The predominant allele has a normal, ...

Homologous Recombination
Homologous recombination is a type of genetic recombination in which genetic information is exchanged between two similar or identical molecules of double-stranded or single-stranded nucleic acids (usually DNA as in cellular organisms but may be also RNA in viruses). Homologous recombination is widely used by cells to accurately DNA repair harmful breaks that occur on both strands of DNA, known as double-strand breaks (DSB), in a process called homologous recombinational repair (HRR). Homologous recombination also produces new combinations of DNA sequences during meiosis, the process by which eukaryotes make gamete cells, like sperm and egg cells in animals. These new combinations of DNA represent genetic variation in offspring, which in turn enables populations to adapt during the course of evolution. Homologous recombination is also used in horizontal gene transfer to exchange genetic material between different strains and species of bacteria and viruses. Horizontal ...

DNA Damage (naturally Occurring)
DNA damage is an alteration in the chemical structure of DNA, such as a break in a strand of DNA, a nucleobase missing from the backbone of DNA, or a chemically changed base such as 8-OHdG. DNA damage can occur naturally or via environmental factors, but is distinctly different from mutation, although both are types of error in DNA. DNA damage is an abnormal chemical structure in DNA, while a mutation is a change in the sequence of base pairs. DNA damages cause changes in the structure of the genetic material and prevents the replication mechanism from functioning and performing properly. The DNA damage response (DDR) is a complex signal transduction pathway which recognizes when DNA is damaged and initiates the cellular response to the damage. DNA damage and mutation have different biological consequences. While most DNA damages can undergo DNA repair, such repair is not 100% efficient. Un-repaired DNA damages accumulate in non-replicating cells, such as cells in the brains o ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
