The protein encoded by this gene belongs to a small group of evolutionarily conserved proteins with three transmembrane domains. It is a potential target for ubiquitination by the Nedd4 family of proteins. This protein is thought to be part of a family of integral Golgi membrane proteins. [provided by RefSeq, Jul 2008],

Function:
developmental stage:Expressed in fetal brain, kidney and lung.,Domain:The WW-binding motifs mediate interaction with NEDD4.,Function:May play a role in Golgi structure maintenance.,PTM:Ubiquitinated by NEDD4; mono-, di- and polyubiquitinated forms are detected. Ubiquitination regulates its degradation.,subunit:Interacts with NEDD4. Interacts in vitro with NEDD4L, SR140, WWP2 and ITCH.,tissue specificity:Widely expressed. Higher levels are detected in cerebellum, pituitary, thalamus, kidney, liver, testis, salivary glands and placenta.,
