WD repeat domain phosphoinositide-interacting protein 1 (WIPI-1), also known as Atg18 protein homolog (ATG18) and WD40 repeat protein interacting with phosphoinositides of 49 kDa (WIPI 49 kDa), is a protein that in humans is encoded by the WIPI1 gene.[4][5][6]

Structure and function

WD40 repeat proteins are key components of many essential biologic functions. They regulate the assembly of multiprotein complexes by presenting a beta-propeller platform for simultaneous and reversible protein–protein interactions. Members of the WIPI subfamily of WD40 repeat proteins, such as WIPI1, have a 7-bladed propeller structure and contain a conserved motif for interaction with phospholipids.[4][6]

gollark: What?

gollark: "Kura Technologies" apparently managed some very impressive things with accursed physicsy optics, but I don't think they're widely available now or have had proper external reviews.

gollark: I'm mostly interested in AR, since a better interface for looking at internet things on the go than my phone would be very convenient.

gollark: Yet most people in developed countries apparently have smartphones now.

gollark: Presumably if they get particularly popular, they'll be available on the technically-worse-but-better-looking-than-buying-it-outright phone-style contracts.
