STX8
Syntaxin-8 is a protein that in humans is encoded by the ''STX8'' gene. Syntaxin 8 directly interacts with HECTd3 and has similar subcellular localization. The protein has been shown to form the SNARE complex with syntaxin 7, vti1b and endobrevin. These function as the machinery for the homotypic fusion of late endosomes. Model organisms Model organisms have been used in the study of STX8 function. A conditional knockout mouse line, called ''Stx8tm2a(EUCOMM)Wtsi'' was generated as part of the International Knockout Mouse Consortium program—a high-throughput mutagenesis project to generate and distribute animal models of disease to interested scientists—at the Wellcome Trust Sanger Institute. Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion. Twenty four tests were carried out on homozygous mutant adult mice, however no significant abnormalities were observed. Interactions STX8 has been shown to interact with ...

VPS18
Vacuolar protein sorting-associated protein 18 homolog is a protein that in humans is encoded by the ''VPS18'' gene. Function Vesicle mediated protein sorting plays an important role in segregation of intracellular molecules into distinct organelles. Genetic studies in yeast have identified more than 40 vacuolar protein sorting (VPS) genes involved in vesicle transport to vacuoles. This gene encodes the human homolog of yeast class C Vps18 protein. The mammalian class C Vps proteins are predominantly associated with late endosomes/lysosomes, and like their yeast counterparts, may mediate vesicle trafficking steps in the endosome/lysosome pathway. Interactions VPS18 has been shown to interact with VPS11 and STX7 Syntaxin-7 is a protein that in humans is encoded by the ''STX7'' gene. In melanocytic cells STX7 gene expression may be regulated by MITF. Interactions STX7 has been shown to interact with STX8, VPS18, Vesicle-associated membrane protein 8 .... References ...

Vesicle-associated Membrane Protein 8
Vesicle-associated membrane protein 8 is a protein that in humans is encoded by the ''VAMP8'' gene. 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. It is associated with the perinuclear vesicular structures of the early endocytic compartment. It has been found that VAMP8 interacts specifically with the soluble NSF-attachment protein (alpha-SNAP), most likely through an VAMP8-containing SNARE complex. Phosphorylation of VAMP8 inside the conserved SNARE-domain can suppress vesicle fusion. Interactions Vesicle-associated membrane protein 8 has been shown to interact with STX4, SNAP23, STX1A, STX8 and STX7 Syntaxin-7 is a protein that in humans is encoded by the ''STX7'' gene.

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] |
Microphthalmia-associated Transcription Factor
Microphthalmia-associated transcription factor also known as class E basic helix-loop-helix protein 32 or bHLHe32 is a protein that in humans is encoded by the ''MITF'' gene. MITF is a basic helix-loop-helix leucine zipper transcription factor involved in lineage-specific pathway regulation of many types of cells including melanocytes, osteoclasts, and mast cells. The term "lineage-specific", since it relates to MITF, means genes or traits that are only found in a certain cell type. Therefore, MITF may be involved in the rewiring of signaling cascades that are specifically required for the survival and physiological function of their normal cell precursors. MITF, together with transcription factor EB (TFEB), TFE3 and TFEC, belong to a subfamily of related bHLHZip proteins, termed the MiT-TFE family of transcription factors. The factors are able to form stable DNA-binding homo- and heterodimers. The gene that encodes for MITF resides at the ''mi'' locus in mice, and its protumor ...
