RAB5A
Ras-related protein Rab-5A is a protein that in humans is encoded by the ''RAB5A'' gene. Function RAB5A localizes to early endosomes where it is involved in the recruitment of RAB7A and the maturation of these compartments to late endosomes. It drives the maturation of endosomes by transporting vacuolar (H+)-ATPases (V-ATPases) from trans-Golgi network to endocytic vesicles. Interactions RAB5A has been shown to interact with: * CHML, * RABEP1, * SDCBP, and * ZFYVE20 Rabenosyn-5 is a protein that in humans is encoded by the ''ZFYVE20'' gene.

Endosome
Endosomes are a collection of intracellular sorting organelles in eukaryotic cells. They are parts of endocytic membrane transport pathway originating from the trans Golgi network. Molecules or ligands internalized from the plasma membrane can follow this pathway all the way to lysosomes for degradation or can be recycled back to the cell membrane in the endocytic cycle. Molecules are also transported to endosomes from the trans Golgi network and either continue to lysosomes or recycle back to the Golgi apparatus. Endosomes can be classified as early, sorting, or late depending on their stage post internalization. Endosomes represent a major sorting compartment of the endomembrane system in cells. Function Endosomes provide an environment for material to be sorted before it reaches the degradative lysosome. For example, low-density lipoprotein (LDL) is taken into the cell by binding to the LDL receptor at the cell surface. Upon reaching early endosomes, the LDL dissociates ...

CHML (gene)
Rab proteins geranylgeranyltransferase component A 2 is an enzyme that in humans is encoded by the ''CHML'' gene. The product of the CHML gene supports geranylgeranylation of most Rab proteins and may substitute for REP-1 in tissues other than retina. CHML is localized close to the gene for Usher syndrome type II. Interactions CHML (gene) has been shown to interact with RAB1A and RAB5A Ras-related protein Rab-5A is a protein that in humans is encoded by the ''RAB5A'' gene.

RABEP1
Rab GTPase-binding effector protein 1 is an enzyme that in humans is encoded by the ''RABEP1'' gene. It belongs to rabaptin protein family.

SDCBP
Syntenin-1 is a protein that in humans is encoded by the ''SDCBP'' gene. Function The protein encoded by this gene was initially identified as a molecule linking syndecan-mediated signaling to the cytoskeleton. The syntenin protein contains tandemly repeated PDZ domains that bind the cytoplasmic, C-terminal domains of a variety of transmembrane proteins. This protein may also affect cytoskeletal-membrane organization, cell adhesion, protein trafficking, and the activation of transcription factors. The protein is primarily localized to membrane-associated adherens junctions and focal adhesions but is also found at the endoplasmic reticulum and nucleus. Alternative splicing results in multiple transcript variants encoding different isoforms. Interactions SDCBP has been shown to interact with: * EFNB1, * GRIK1, * GRIK2, * Interleukin 5 receptor alpha subunit, * Merlin, * RAB5A, * SOX4, * TRAF6, * ULK1 ULK1 is an enzyme that in humans is encoded by the ''ULK1'' 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] |
RAB7A
Ras-related protein Rab-7a is a protein that in humans is encoded by the ''RAB7A'' gene. Ras-related protein Rab-7a is involved in endocytosis, which is a process that brings substances into a cell. The process of endocytosis works by folding the cell membrane around a substance outside of the cell (for example a protein) and then forms a vesicle. The vesicle is then brought into the cell and cleaved from the cell membrane. RAB7A plays an important role in the movement of vesicles into the cell as well as with vesicle trafficking. Various mutations of RAB7A are associated with Hereditary sensory neuropathy type 1C (HSN IC), also known as Charcot-Marie-Tooth syndrome type 2B (CMT2B). Function Members of the RAB family of RAS-related GTP-binding proteins are important regulators of vesicular transport and are located in specific intracellular compartments. RAB7 has been localized to late endosomes and shown to be important in the late endocytic pathway. In addition, it has b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
V-ATPase
Vacuolar-type ATPase (V-ATPase) is a highly conserved evolutionarily ancient enzyme with remarkably diverse functions in eukaryotic organisms. V-ATPases acidify a wide array of intracellular organelles and pumps protons across the plasma membranes of numerous cell types. V-ATPases couple the energy of ATP hydrolysis to proton transport across intracellular and plasma membranes of eukaryotic cells. It is generally seen as the polar opposite of ATP synthase because ATP synthase is a proton channel that uses the energy from a proton gradient to produce ATP. V-ATPase however, is a proton pump that uses the energy from ATP hydrolysis to produce a proton gradient. The Archaea-type ATPase (A-ATPase) is a related group of ATPases found in archaea that often work as an ATP synthase. It forms a clade V/A-ATPase with V-ATPase. Most members of either group shuttle protons (), but a few members have evolved to use sodium ions () instead. Roles played by V-ATPases V-ATPases are foun ...
