domain:The FYVE-type zinc finger domain mediates interactions with phosphatidylinositol 3-phosphate.,function:Binds phospholipid vesicles containing phosphatidylinositol 3-phosphate and participates in early endosomal trafficking.,PTM:Phosphorylated upon DNA damage, probably by ATM or ATR.,PTM:Phosphorylation on Tyr-389 and/or Tyr-400 is required for interaction with BMX and endosomal targeting.,similarity:Contains 1 FYVE-type zinc finger.,similarity:Contains 1 RUN domain.,subunit:Interacts with BMX. May interact with SSB. Interacts with RAB4 and RAB5 that have been activated by GTP-binding.,tissue specificity:Broadly expressed, with highest levels in lung, testis, kidney and brain.,
Cytoplasm. Early endosome membrane; Peripheral membrane protein.
