SPRED3
Sprouty-related, EVH1 domain-containing protein 3 also known as Spread-3 is a protein that in humans is encoded by the ''SPRED3'' gene. Spread-3 is a member of the Sprouty (see SPRY1/SPRED) family of proteins that regulate growth factor A growth factor is a naturally occurring substance capable of stimulating cell proliferation, wound healing, and occasionally cellular differentiation. Usually it is a secreted protein or a steroid hormone. Growth factors are important for ...-induced activation of the MAP kinase cascade.

EVH1 Domain
WH1 domains, also known as EVH1 domains, are evolutionary conserved protein domain, protein domains found on WASP (VASP) proteins, which are often involved in actin polymerization. Function WH1 domains are important for all cellular processes involving actin, this includes cell motility, cell trafficking, cell division and cytokinesis, cell signalling, and the establishment and maintenance of cell junctions and cell shape. Structure Protein tertiary structure, Tertiary structure of the WH1 domain of the ENAH (gene), Mena protein revealed cis-regulatory element, structure similarities with the pleckstrin homology domain, pleckstrin (PH) domain. The overall protein folding, fold consists of a compact parallel beta-sandwich, closed along one edge by a long alpha helix. A highly conservation (genetics), conserved cluster of three surface-exposed aromatic Side chain, side-chains forms the recognition site for the molecule's target ligand (biochemistry), ligands.

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Growth Factor
A growth factor is a naturally occurring substance capable of stimulating cell proliferation, wound healing, and occasionally cellular differentiation. Usually it is a secreted protein or a steroid hormone. Growth factors are important for regulating a variety of cellular processes. Growth factors typically act as signaling molecules between cells. Examples are cytokines and hormones that bind to specific receptors on the surface of their target cells. They often promote cell differentiation and maturation, which varies between growth factors. For example, epidermal growth factor (EGF) enhances osteogenic differentiation ( osteogenesis or bone formation), while fibroblast growth factors and vascular endothelial growth factors stimulate blood vessel differentiation ( angiogenesis). Comparison to cytokines ''Growth factor'' is sometimes used interchangeably among scientists with the term '' cytokine.'' Historically, cytokines were associated with hematopoietic (b ...

MAPK/ERK Pathway
The MAPK/ERK pathway (also known as the Ras-Raf-MEK-ERK pathway) is a chain of proteins in the cell (biology), cell that communicates a signal from a Receptor (biochemistry), receptor on the surface of the cell to the DNA in the nucleus of the cell. The signal starts when a signaling molecule binds to the receptor on the cell surface and ends when the DNA in the nucleus expresses a protein and produces some change in the cell, such as cell division. The pathway includes many proteins, such as mitogen-activated protein kinases (MAPKs), originally called extracellular signal-regulated kinases (ERKs), which communicate by adding phosphate groups to a neighboring protein (Phosphorylation, phosphorylating it), thereby acting as an "on" or "off" switch. When one of the proteins in the pathway is mutated, it can become stuck in the "on" or "off" position, a necessary step in the development of many cancers. In fact, components of the MAPK/ERK pathway were first discovered in cancer cells ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
