DEK (gene)
The human ''DEK'' gene encodes the DEK protein. Function This gene encodes a protein with one SAP domain. The protein binds to cruciform and superhelical DNA and induces positive supercoils into closed circular DNA. It is also involved in splice site selection during mRNA processing. Chromosomal aberrations involving this region increased expression of this gene and the presence of antibodies against this protein are all associated with various diseases. Interactions ''DEK'' interacts with TFAP2A Transcription factor AP-2 alpha (Activating enhancer binding Protein 2 alpha), also known as TFAP2A, is a protein that in humans is encoded by the ''TFAP2A'' gene. Function Transcription factor AP-2 alpha is a 52-kD sequence-specific DNA-bindi ....

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 ...

Messenger RNA
In molecular biology, messenger ribonucleic acid (mRNA) is a single-stranded molecule of RNA that corresponds to the genetic sequence of a gene, and is read by a ribosome in the process of synthesizing a protein. mRNA is created during the process of transcription, where an enzyme (RNA polymerase) converts the gene into primary transcript mRNA (also known as pre-mRNA). This pre-mRNA usually still contains introns, regions that will not go on to code for the final amino acid sequence. These are removed in the process of RNA splicing, leaving only exons, regions that will encode the protein. This exon sequence constitutes mature mRNA. Mature mRNA is then read by the ribosome, and, utilising amino acids carried by transfer RNA (tRNA), the ribosome creates the protein. This process is known as translation. All of these processes form part of the central dogma of molecular biology, which describes the flow of genetic information in a biological system. As in DNA, genetic inf ...

TFAP2A
Transcription factor AP-2 alpha (Activating enhancer binding Protein 2 alpha), also known as TFAP2A, is a protein that in humans is encoded by the ''TFAP2A'' gene. Function Transcription factor AP-2 alpha is a 52-kD sequence-specific DNA-binding protein that enhances transcription of specific genes by binding to a GC-rich DNA sequence first identified in the cis-regulatory region of SV40 virus DNA and in cis-regulatory regions of a variety of cellular genes. The TFAP2-alpha gene was isolated and found to be retinoic acid-inducible in NT2 teratocarcinoma cells suggesting a potential role for AP-2 alpha in cellular differentiation. During embryonic development, AP-2 alpha is expressed in neural crest cells migrating from the cranial neural folds during neural tube closure, and is also expressed in ectoderm, parts of the central nervous system, limb buds, and mesonephric system suggesting that AP-2 alpha plays an important role in the determination and development of these ti ...
