Associates with cyclin G and CDK5. Seems to act as an auxilin homolog that is involved in the uncoating of clathrin-coated vesicles by Hsc70 in non-neuronal cells. Expression oscillates slightly during the cell cycle, peaking at G1.
Subcellular locations: Cytoplasm, Perinuclear region, Golgi apparatus, Trans-Golgi network, Cell junction, Focal adhesion
Localizes to the perinuclear area and to the trans-Golgi network. Also seen on the plasma membrane, probably at focal adhesions.
Ubiquitous. Highest in testis.
