LHX6
LIM/homeobox protein Lhx6 is a protein that in humans is encoded by the ''LHX6'' gene. This gene encodes a member of a large protein family that contains the LIM domain LIM domains are protein structural domains, composed of two contiguous zinc fingers, separated by a two-amino acid residue hydrophobic linker. The domain name is an acronym of the three genes in which it was first identified (LIN-11, Isl-1 and M ..., a unique cysteine-rich zinc-binding domain. The encoded protein may function as a transcriptional regulator and may be involved in the control of differentiation and development of neural and lymphoid cells. Two alternatively spliced transcript variants encoding distinct isoforms have been described for this gene. Alternatively spliced transcript variants have been identified, but their biological validity has not been determined.

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] |
LIM Domain
LIM domains are protein structural domains, composed of two contiguous zinc fingers, separated by a two-amino acid residue hydrophobic linker. The domain name is an acronym of the three genes in which it was first identified (LIN-11, Isl-1 and MEC-3). LIM is a protein interaction domain that is involved in binding to many structurally and functionally diverse partners. The LIM domain appeared in eukaryotes sometime prior to the most recent common ancestor of plants, fungi, amoeba and animals. In animal cells, LIM domain-containing proteins often shuttle between the cell nucleus where they can regulate gene expression, and the cytoplasm where they are usually associated with actin cytoskeletal structures involved in connecting cells together and to the surrounding matrix, such as stress fibers, focal adhesions and adherens junctions. Discovery LIM domains are named after their initial discovery in the three homeobox proteins that have the following functions: * Lin-11 – as ...

Cysteine-rich Protein
Cysteine-rich proteins (CRP, cysteine-rich peptide or disulphide-rich peptide) are small proteins that contain a large number of cysteines. These cysteines either cross-link to form disulphide bonds, or bind metal ions by chelation, stabilising the protein's tertiary structure. CRPs include a highly conserved secretion peptide signal at the N-terminus and a cysteine-rich region at the C-terminus. Structure Disulphides In an oxidising environment cysteines cross-link to form disulphide bonds. CRPs that form these typically have an even number of cysteines. Metal binding Cysteines can coordinate one or more metal ions by forming a chelation complex around them. Functions in plants CRPs are numerous in plants, with 756 CRP-encoding genes in the ''Arabidopsis thaliana'' genome. Several CRPs bind known receptors, but most CRP signaling mechanisms and protein interactions are uncharacterized. Characterized CRPs function as short-range intercellular signals during processes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
