Alpha-mannosidase 2 is an enzyme that in humans is encoded by the MAN2A1 gene.[4][5][6]

Function

This gene encodes a protein which is a member of family 38 of the glycosyl hydrolases. The protein is located in the Golgi apparatus and catalyzes the final hydrolytic step in the asparagine-linked oligosaccharide (N-linked glycosylation) maturation pathway. Mutations in the mouse homolog of this gene have been shown to cause a systemic autoimmune disease similar to human systemic lupus erythematosus.[6]

gollark: You could just use the rednet_message event, no?

gollark: I have it open right now.

gollark: It does.

gollark: The server backups were apparently broken for a while due to a potatOS feature interacting oddly with tar.

gollark: <@!222424031368970240> From what they said elsewhere, SC is dead because "kaori", the dedicated server they run SC and other stuff on, failed in some way.
