VAMP4
Vesicle-associated membrane protein 4 is a protein that in humans is encoded by the ''VAMP4'' gene. Function Synaptobrevins/VAMPs, syntaxins, and the 25-kD synaptosomal-associated protein SNAP25 are the main components of a protein complex involved in the docking and/or fusion of synaptic vesicles with the presynaptic membrane. The protein encoded by this gene is a member of the vesicle-associated membrane protein (VAMP)/synaptobrevin family. This protein may play a role in trans-Golgi network-to-endosome transport. Interactions VAMP4 has been shown to interact with AP1M1, STX6 and STX16 Syntaxin-16 is a protein that in humans is encoded by the ''STX16'' gene. It has been associated with pseudohypoparathyroidism type Ib. Losing this gene causes loss of methylation at GNAS1 exon A/B. Interactions STX16 has been shown to inter ....

AP1M1
AP-1 complex subunit mu-1 is a protein that in humans is encoded by the ''AP1M1'' gene. Function The protein encoded by this gene is the medium chain of the trans-Golgi network clathrin-associated protein complex AP-1. The other components of this complex are beta-prime-adaptin, gamma-adaptin, and the small chain AP1S1. This complex is located at the Golgi vesicle and links clathrin to receptors in coated vesicles. These vesicles are involved in endocytosis and Golgi processing. Interactions AP1M1 has been shown to interact with VAMP4 and AP1G1 AP-1 complex subunit gamma-1 is a protein that in humans is encoded by the ''AP1G1'' gene. Function Adaptins are important components of clathrin-coated vesicles transporting ligand-receptor complexes from the plasma membrane or from the trans ....

STX6
Syntaxin-6 is a protein that in humans is encoded by the ''STX6'' gene. Interactions STX6 has been shown to interact with SNAP23, VAMP3 and VAMP4. N terminal protein domain The protein domain Syntaxin 6 N terminal protein domain is a soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) found in endosomal transport vesicles. It is part of the family, of target SNAREs (t-SNAREs). It is a vital aid to exporting and importing cell cargo through a process called cell trafficking. Its SNARE motif shows significant homology to both syntaxin 1a and S25C, indicating similarity through evolutionary conservation. The structure of the syntaxin 6 N-terminal domain shows strong structural similarity with the N-terminal domains of syntaxin 1a, Sso1p, and Vam3p; despite a very low level of sequence similarity. SNARE functions essentially as a tether to hold the vesicle. The cytoplasmic regions of SNARE found on transport vesicles and target membranes interact, then ...

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] |
