ATP6V1G2 is a subunit of a protein that has been identified in cell membranes, including intracellular membranes. These include lysosome, vacuole, and vesicle membranes within the cell.

ATP6V1G2 is made of 118 amino acids. ATP6V1G2 can make the pH of certain areas lower.

The biochemistry ATP6V1G2 is required for biological function.

ATP6V1G2 is mostly found in the brain, and a smaller amount is found in the adrenals. The enzyme is coded for by 4 exons. The enzyme serves three main functions within the cell. First, ATP is hydrolyzed by this enzyme. This means that ATP is broken down with water into ADP and a Hydrogen ion. This Hydrogen ion serves as energy to drive other processes. ATP6V1G2 also allows other proteins to bind within the cell. ATP6V1G2 also allows ATPase to work by bringing Hydrogen ions into the cell.

The biochemical abilities of ATP6V1G2 are involved in two other processes. The first one includes managing autophagy within the cell. The second is the decrease in pH of vesicles in the synapse.

ATP6V1G2 is the specific part of the enzyme that hydrolyses ATP as a peripheral protein.

Dysfunction of ATP6V1G2 leads to various disorders. These can include "Noonan Syndrome 9," "Distal Renal Tubular Acidosis," and "Noonan Syndrome 3." .

ATP6V1G2 has significant functions regarding the function of nerve signals. . The acidification of the interior of vesicles by ATP6V1G2 creates a difference in pH that is required for the neurotransmitters to enter the vesicle. . In this way, ATP6V1G2 allows for the preparation of neurotransmitters in the nerve vesicle.

The decrease in pH by ATP6V1G2 in the vesicle is important in the function of vesicle binding to the SNARE protein and endocytosis. .

Activation of a nerve causes lower pH in the vesicles, and a larger pH in the cell.

Calcium and hydrogen antiporters are required for ATP6V1G2 to acidify the inside of the vesicle. The calcium is required to exit the cell in order to increase the number of hydrogens. ATP6V1G2 lowers the proton concentration in the cell by the vesicle binding to the plasma membrane and lowering the concentration of the protons.

The ATP6V1G2 functions to prepare the vesicle for neurotransmitters to enter the vesicle, the binding of the vesicle to the plasma membrane, and the endocytosis of the vesicle.

There are approximately 45,000 ATP6V1G2 proteins in the membrane, with "150 proton pumps per" micrometers squared.

ATP6V1G2 is a subunit of a protein. It is in eukaryotic cells. It pumps protons. It is usually in internal plasma membranes. The V1 portion of the protein "is an ATPase" and is outside of the plasma membrane. ATP is required for hydrogens to enter the vesicle. . The V0 part of the protein is in the plasma membrane and the "a subunit" is used to determine the isoform of the protein. Different isoforms are found in different tissues in mammals. The release of V1 from V0 after protons have entered the vesicle and neurotransmitters, allows the V0 domain to travel with the vesicle to bind to another V0 domain and transfer the neurotransmitters.

There is a set amount of G2 and G1 subunits of the protein.

vATPase helps in the process of neurotransmitters being brought into the vesicle and in the binding of the vesicle to the synapse. . The ATP6V1G2 part of the vATPase offers catalytic ability. ATP6V1G2 is needed for function, however, no abnormalities were seen in its absence in the experiment of turning off the gene in mice. ATP6V1G1 was increased when ATP6V1G2 was not present. There was not more mRNA with the absence of ATP6V1G2. More ATP6V1G1 was made without increased transcription.

ATP6V1G2 completes processes involved with moving substances within the cell, as well as membranes, and the digestion of food.

The functioning of vATPase is required for life. The processes of vATPase allows for the immune cells to remove microorganisms, by the macrophage. The vATPase also allows for T-cells and antigens to function. The vATPase is also involved in acidifying the extracellular area of "bone resorbing osteoclasts," and "epithelial cells in the kidney."

The ATP6V1G2 is the part of the protein that connects the V1 and V0 components of the protein together. The ATP6V1G2 is required for the "energy coupling" between V1 and V0, allowing V1 and V0 to attach or unattach. The G component of vATPase weighs 13 kDa. . ATP6V1G2 is found in the brain. The experiment of creating a nonfunctional ATP6V1G2 gene in mice created no effects for offspring. ATP6V1G2 is involved in ATP hydrolysis. ATP6V1G2 was not able to substitute for Vma10 decrease, while ATP6V1G1 was.

ATP6V1G2 may be involved in autoimmune diseases. Activated macrophages created more ATP6V1G2. The ATP6V1G2 gene is found in a 122kb group in the "TNF locus." The increased ATP6V1G2 was independent of TNF. The mRNA determines how much ATP6V1G2 is made because of an activated macrophage. ATP6V1G2 may be a result of the inflammatory response. ATP6V1G2 is involved with "protein sorting and degradation," "generation of secretory granules and endocytosis, and is known to be important for inflammatory and immune cell differentiation and function." Factors like increased salt can increase vATPase. Neutrophils, "degranulation," and "phagocytosis" from protein kinase C increases vATPase. vATPase activity creates immune response against pathogens by macrophage activation. Dendritic cells require vATPase to mature.
