What does the VMAT2 gene do?



 Let's imagine our brain is like a big playground, and there are messengers called neurotransmitters that help different parts of the playground communicate with each other. These messengers are like little notes that travel between friends to make sure everyone knows what's happening.

Now, think of the VMAT2 gene as a helper that puts these messenger notes into special backpacks, called vesicles, and then sends them to the right places on the playground.

These messengers, or neurotransmitters, are super important for things like making sure you feel happy, paying attention, and moving your muscles. If the helper (VMAT2 gene) doesn't do its job correctly, the messengers might not get to the right places at the right times, and that can sometimes cause problems with how we feel and act.

Scientists are like detectives trying to understand how this helper gene works and how it might be connected to some things that can make people feel not-so-great, like when they have trouble moving, paying attention, or feeling happy.

Remember, our bodies are like big, amazing puzzles, and scientists are always working to figure out how all the pieces fit together to keep us healthy and happy!


The VMAT2 gene, or vesicular monoamine transporter 2, is integral to the intracellular transport of monoamine neurotransmitters, including dopamine, norepinephrine, and serotonin. It facilitates the movement of these neurotransmitters from the cytoplasm of nerve cells into vesicles, which are small membrane-bound sacs within nerve cells responsible for storing and releasing neurotransmitters. This transportation process is vital for effective neurotransmission, the mechanism through which nerve cells communicate. Neurotransmitters act as chemical messengers, participating in diverse physiological functions such as mood regulation, motor control, and cognitive processes.

VMAT2 specifically plays a crucial role in packaging monoamine neurotransmitters into vesicles, ensuring their controlled release into the synapse, the junction between two nerve cells. This regulated release is essential for maintaining the precise balance and coordination of neural signaling in the brain. Genetic variations or mutations in the VMAT2 gene may impact the function of the vesicular monoamine transporter 2, influencing neurotransmitter storage and release. Such alterations have been linked to neurological and psychiatric conditions like Parkinson's disease, schizophrenia, bipolar disorder, and depression. However, it's crucial to recognize the complexity of these conditions, influenced by a combination of genetic and environmental factors. Ongoing research aims to elucidate the intricate mechanisms by which genetic variations in VMAT2

Complex layers of human social behavior. Could it be that these are subconscious echoes of ancestral encounters between us modern Humans- Homo_Sapiens ALIAS '' Homo diddyoil'' and Homo_Neanderthals?

  What if some of the traits we see in people from Europe, Africa, and Asia—particularly in India [ Dalits or their so called Black untouchables] —are in today's world of free education / much improved scientific chivalry and honesty from even European/ Arab/ Asian ETC scientists blatant manifestations of deeply embedded Neanderthal genetics, subconsciously influencing behavior even today? Does the intelligence of anyone who thinks this has no basis or who finds this deduction totally illogical need to be questioned, scrutinized before God, Man and Data.   One striking example is the town of Orania in South Africa, a place where racial segregation continues as you read, and Black residents are notably absent despite being in the heart of a predominantly Black continent.  Orania is in South Africa which is a country, a prominent country in Africa. While this isn't an attempt to cast blame solely on the so described and titled separately, the separatists called Oranian...

Elon Musk Is the Perfect FAKE White Man: The Epitome of FAKE White Mentality—This Is Why FAKE White People Hate Him (Beyond His Wealth). The Ancestors Sent Him to Expose the Nature They Have Killed Us for, ''FOR''... Merely Highlighting Since They Came From The Caves Of Planet Closet Nazis..

For centuries, white people have built a global myth —the idea that Black men are irresponsible fathers, abandoning their children, leaving broken homes. This lie has been used to justify every racist policy imaginable, from mass incarceration to economic disenfranchisement. It has been a psychological weapon to strip Black men of dignity while upholding whiteness as the moral standard. But now, in the year 202X, the perfect white man—the whitest of them all —has arrived to shatter their carefully constructed illusion. Elon Musk, the richest man in the world, a walking monument to white entitlement, is proving that white men have always been the blueprint for reckless reproduction, strategic neglect, and the abandonment of their own blood. He has fathered at least 11 children with multiple women, scattered them across the world like colonial outposts, and yet—where is the white outrage?  Where is the global condemnation that Black men face for merely existing?  Where are the...

Supercavitation: UAV's, Whatever's Zipping Through Our Skies, Time Dilation [ Travel ] Drag Cancellation And Jump Rooms/ Jump Points Technology

 Technology, Time, and Mystery: Are UFOs Hiding in Plain Physics? The world of cutting-edge technology and unexplained stuff often converge in  bat shit crazy ways, leading to provocative questions about the limits of our understanding.  Take, for instance, the principle of supercavitation, a technological grey-out used in high-speed underwater weaponry. This innovation creates a gas bubble around a projectile, drastically reducing drag and enabling astonishing speeds. Imagine applying this principle not to torpedoes slicing through water, but to unidentified flying objects (UFOs) zipping through our skies and beyond. Could similar mechanisms—on an entirely different scale—explain some of the irrational, nowadays unavoidable reported global cases of UFO sightings? Supercavitation: Redefining Speed Supercavitation technology, seen in devices like Russia’s VA-111 Shkval torpedo, shows how innovation can defy conventional limitations. By creating a "bubble" of air around an ...
