MCOLN3
Mucolipin-3 also known as TRPML3 (transient receptor potential cation channel, mucolipin subfamily, member 3) is a protein that in humans is encoded by the MCOLN3 gene.[5] It is a member of the small family of the TRPML channels, a subgroup of the large protein family of TRP ion channels.[6]
Gene
In human, the MCOLN3 gene resides on the short arm of chromosome 1 at 1p22.3. The gene is split in 12 exons, which entail the open reading frame of 1659 nucleotides. The encoded protein, TRPML3, has 553 amino acid with a predicted molecular weight of ≈64 kDa. Computational analyses of the secondary structure predict the presence of six transmembrane domains, an ion transport motif (PF00520) and a transient receptor potential motif (PS50272). In the mouse, Mcoln3, is located on the distal end of chromosome 3 at cytogenetic band qH2. Human and mouse TRPML3 proteins share 91% sequence identity.[7] All vertebrate species, for which a genomic sequence is available, harbor the MCOLN3 gene. Homologs of MCOLN3 are also present in the genome of insects (Drosophila melanogaster), nematodes (Caenorhabditis elegans), sea urchin (Strongylocentrotus purpuratus) and lower organisms including Hydra and Dictyostelium.

Phenotypes
Mutations of the MCOLN3 gene in mice result in auditory hair cell death and deafness.[8]

gollark: "Features:- Fortunes/Dwarf Fortress output/Chuck Norris jokes on boot (wait, IS this a feature?)- (other) viruses (how do you get them in the first place? running random files like this?) cannot do anything particularly awful to your computer - uninterceptable (except by crashing the keyboard shortcut daemon, I guess) keyboard shortcuts allow easy wiping of the non-potatOS data so you can get back to whatever nonsense you do fast- Skynet (rednet-ish stuff over websocket to my server) and Lolcrypt (encoding data as lols and punctuation) built in for easy access!- Convenient OS-y APIs - add keyboard shortcuts, spawn background processes & do "multithreading"-ish stuff.- Great features for other idio- OS designers, like passwords and fake loading (est potatOS.stupidity.loading [time], est potatOS.stupidity.password [password]).- Digits of Tau available via a convenient command ("tau")- Potatoplex and Loading built in ("potatoplex"/"loading") (potatoplex has many undocumented options)!- Stack traces (yes, I did steal them from MBS)- Backdoors- er, remote debugging access (it's secured, via ECC signing on disks and websocket-only access requiring a key for the other one)- All this useless random junk can autoupdate (this is probably a backdoor)!- EZCopy allows you to easily install potatOS on another device, just by sticking it in the disk drive of any potatOS device!- fs.load and fs.dump - probably helpful somehow.- Blocks bad programs (like the "Webicity" browser).- Fully-featured process manager.- Can run in "hidden mode" where it's at least not obvious at a glance that potatOS is installed.- Convenient, simple uninstall with the "uninstall" command.- Turns on any networked potatOS computers!- Edits connected signs to use as ad displays.- A recycle bin.- An exorcise command, which is like delete but better.- Support for a wide variety of Lorem Ipsum."
gollark: You would need to get rid of the autoupdate capabilities of potatOS itself, or swap them to your own pastebins/github stuff, and then keep everything in line with the current versions.
gollark: Anyway, <@151391317740486657>, what you can do is fork potatOS and get rid of the bits you don't like, but that's also hard (less, though) and would be very difficult to keep updated.
