ZFYVE1

The FYVE domain mediates the recruitment of proteins involved in membrane trafficking and cell signaling to phosphatidylinositol 3-phosphate-containing membranes. This protein contains two zinc-binding FYVE domains in tandem and is reported to localize to the Golgi apparatus. Alternative splicing results in multiple transcript variants.

Full Name

Zinc Finger FYVE-Type Containing 1

Function

Plays a role in the formation of lipid droplets (LDs) which are storage organelles at the center of lipid and energy homeostasis (PubMed:30970241).
Regulates the morphology, size and distribution of LDs (PubMed:31293035, PubMed:30970241).
Mediates the formation of endoplasmic reticulum-lipid droplets (ER-LD) contacts by forming a complex with RAB18 and ZW10 (PubMed:30970241).
Binds to phosphatidylinositol 3-phosphate (PtdIns3P) through FYVE-type zinc finger (PubMed:11739631, PubMed:11256955).

Resides predominantly in the cisternal stacks of the Golgi (PubMed:11256955).
Colocalizes with TRIM13 on the perinuclear endoplasmic reticulum (PubMed:22178386).
During starvation conditions, localizes to omegasomes which are endoplasmic reticulum connected strutures at the origin of preautophagosomal structures (PubMed:31293035, PubMed:25876663).
Localizes to lipid droplets in the presence of oleic acid (PubMed:31293035, PubMed:30970241).
