BRD9
Bromodomain-containing protein 9 is a protein that in humans is encoded by the ''BRD9'' gene. Structure and interaction BRD9 contains a bromodomain. It is closely related to BRD7. BRD9 is present in some SWI/SNF ATPase remodeling complexes. Role in cancer The BRD9 gene is frequently present in variable copy number in lung cancer. Small molecule inhibition Small molecules capable of binding to the bromodomain of BRD9 have been developed.

Bromodomain
A bromodomain is an approximately 110 amino acid protein domain that recognizes acetylated lysine residues, such as those on the ''N''-terminal tails of histones. Bromodomains, as the "readers" of lysine acetylation, are responsible in transducing the signal carried by acetylated lysine residues and translating it into various normal or abnormal phenotypes. Their affinity is higher for regions where multiple acetylation sites exist in proximity. This recognition is often a prerequisite for protein-histone association and chromatin remodeling. The domain itself adopts an all-α protein fold, a bundle of four alpha helices each separated by loop regions of variable lengths that form a hydrophobic pocket that recognizes the acetyl lysine. Discovery The bromodomain was identified as a novel structural motif by John W. Tamkun and colleagues studying the Drosophila gene ''Brahma''/''brm'', and showed sequence similarity to genes involved in transcriptional activation. The name "bromo ...

SWI/SNF
In molecular biology, SWI/SNF (SWItch/Sucrose Non-Fermentable), is a subfamily of ATP-dependent chromatin remodeling complexes, which is found in eukaryotes. In other words, it is a group of proteins that associate to remodel the way DNA is packaged. This complex is composed of several proteins – products of the SWI and SNF genes (, /, , , ), as well as other polypeptides. It possesses a DNA-stimulated ATPase activity that can destabilize histone-DNA interactions in reconstituted nucleosomes in an Adenosine triphosphate, ATP-dependent manner, though the exact nature of this structural change is unknown. The SWI/SNF subfamily provides crucial nucleosome rearrangement, which is seen as ejection and/or sliding. The movement of nucleosomes provides easier access to the chromatin, enabling binding of specific transcription factors, and allowing genes to be activated or repressed. The human analogs of SWI/SNF are "SMARCA4, BRG1- or SMARCA2, BRM-associated factors", or BAF (SWI/SNF-A) ...

Protein
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residue (biochemistry), residues. Proteins perform a vast array of functions within organisms, including Enzyme catalysis, catalysing metabolic reactions, DNA replication, Cell signaling, responding to stimuli, providing Cytoskeleton, structure to cells and Fibrous protein, organisms, and Intracellular transport, transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the Nucleic acid sequence, nucleotide sequence of their genes, and which usually results in protein folding into a specific Protein structure, 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 pep ...

Gene
In biology, the word gene has two meanings. The Mendelian gene is a basic unit of heredity. 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 non-coding genes. During gene expression (the synthesis of Gene product, RNA or protein from a gene), DNA is first transcription (biology), copied into RNA. RNA can be non-coding RNA, directly functional or be the intermediate protein biosynthesis, template for the synthesis of a protein. The transmission of genes to an organism's offspring, is the basis of the inheritance of phenotypic traits from one generation to the next. These genes make up different DNA sequences, together called a genotype, that is specific to every given individual, within the gene pool of the population (biology), population of a given species. The genotype, along with environmental and developmental factors, ultimately determines the phenotype ...

BRD7
Bromodomain-containing protein 7 is a protein that in humans is encoded by the ''BRD7'' gene. Interactions BRD7 has been shown to interact with IRF2 and HNRPUL1. Azoospermia BRD7 protein is a transcription regulator that is normally highly expressed in the testis, particularly in meiotic pachytene and diplotene spermatocytes and in round spermatids. However, in the testes of patients exhibiting spermatogenesis arrest and azoospermia, BRD7 protein expression is observed to be absent or reduced. Homozygous knockout mice RD7(-/-)are infertile and have increased DNA damage and apoptosis in their germline In biology and genetics, the germline is the population of a multicellular organism's cells that develop into germ cells. In other words, they are the cells that form gametes ( eggs and sperm), which can come together to form a zygote. They dif ....
