FYVE Domains
In molecular biology the FYVE zinc finger domain is named after the four cysteine-rich proteins: Fab 1 (yeast orthologue of PIKfyve), YOTB, Vac 1 (vesicle transport protein), and EEA1, in which it has been found. FYVE domains bind phosphatidylinositol 3-phosphate, in a way dependent on its metal ion coordination and basic amino acids. The FYVE domain inserts into cell membranes in a pH-dependent manner. The FYVE domain has been connected to vacuolar protein sorting and endosome function. Structure The FYVE domain is composed of two small beta hairpins (or zinc knuckles) followed by an alpha helix. The FYVE finger binds two zinc ions. The FYVE finger has eight potential zinc coordinating cysteine positions and is characterized by having basic amino acids around the cysteines. Many members of this family also include two histidines in a sequence motif: The FYVE finger is structurally similar to the RING domain and the PHD finger.

EEA1
The gene EEA1 encodes for the 1400 amino acid protein, Early Endosome Antigen 1. EEA1 localizes exclusively to early endosomes and has an important role in endosomal trafficking. EEA1 binds directly to the phospholipid phosphatidylinositol 3-phosphate through its C-terminal FYVE domain and forms a homodimer through a coiled coil. EEA1 acts as a tethering molecule that couples vesicle docking with SNARE (protein), SNAREs such as N-ethylmaleimide sensitive fusion protein, bringing the endosomes physically closer and ultimately resulting in the fusion and delivery of endosomal cargo. Function EEA1 is a RAB5A effector protein which binds via an N-terminal zinc finger domain and is required for fusion of early and late endosomes and for sorting at the early endosome level. EEA1 plays a role in endocytosis and is recruited by Rab5-GTP to endosomal membranes. EEA1 may be regulated through monoubiquination, affecting endosome fusion and trafficking.

RUFY2
RUN and FYVE domain containing 2 (RUFY2) is a protein that in humans is encoded by the ''RUFY2'' gene. The RUFY2 gene is named for two of its domains, the RUN domain and FYVE domains. RUFY2 is a member of the RUFY family of proteins that include RUFY1, RUFY2, RUFY3, and RUFY4. RUFY2 protein has a dynamic role in endosomal membrane trafficking. Gene The human ''RUFY2'' gene is located on the long (q) arm of chromosome 10 (human), chromosome 10 at region 21 band 3, from base pair 70,100,864 to base pair 70,167,051 on the reverse strand (Build GRCh37/hg19(map) The gene produces a 2,080 base pair mRNA. There are 18 predicted exons in the human gene with 13 alternative transcripts. Gene neighborhood 8,180 base pairs upstream of RUFY2 is the protein-coding gene for phenazine biosynthesis-like protein domain containing (PBLD). While 6,770 base pairs downstream from RUFY2 is a DNA2 conserved helicase/nuclease involved in the maintenance of mitochondrial and nuclear DNA stability. ...

This gene encodes a member of the myotubularin dual specificity protein phosphatase gene family. The encoded protein is structurally similar to myotubularin but in addition contains a FYVE domain and an N-terminal PH-GRAM domain. The protein can self-associate and also form heteromers with another myotubularin related protein. The protein binds to phosphoinositide lipids through the PH-GRAM domain, and can hydrolyze phosphatidylinositol(3)-phosphate and phosphatidylinositol(3,5)-biphosphate in vitro. The encoded protein has been observed to have a perinuclear, possibly membrane-bound, distribution in cells, but it has also been found free in ...
