  • perinuclear area and to the trans-Golgi network
  • on the plasma membrane, probably at focals adhesions
  • GAK localizes in both cytoplasm and nucleus
  • translocated from the centrosome to chromatin at the end of telophase
  • basic FUNCTION
  • may be acting as an auxilin homolog that is involved in the uncoating of clathrin- coated vesicles by hsc70 in non-neuronal cell
  • regulates clathrin-mediated membrane trafficking in the cytoplasm
  • important function of GAK in the nucleus
  • two novel functions of GAK: maintenance of proper centrosome maturation and of mitotic chromosome congression
  • GAK and CLTC function cooperatively not only in endocytosis, but also in mitotic progression
  • is a novel regulator of microtubule generation at kinetochores/chromatin
  • role for GAK and clathrin in microtubule outgrowth from kinetochores/chromosomes, suggesting that GAK acts through clathrin to control microtubule outgrowth around chromosomes
  • acting as a protein serine/threonine kinase
  • is a key regulator of clathrin-coated vesicle trafficking and plays a central role during development
  • CELLULAR PROCESS cell cycle
  • regulation of cell cycle
    a component
    small molecule nucleotide,
  • binding to cyclin G and CDK5
  • is an essential cofactor for HSPA8-dependent uncoating of clathrin-coated vesicles
  • interaction of GAK with adaptor protein 1 (JUN) regulates lysosomal enzyme sorting
  • GAK and SNCA interact in a pathway involved in Parkinson disease pathogenesis
  • interacting with CREBBP, in embryonic orofacial tissue
  • GAK modifies SNCA expression levels and affects susceptibility to Parkinson disease
