Subcellular location [CC]Cytoplasm. Cytoplasm, perinuclear region. Cell membrane;
Peripheral membrane protein;
Cytoplasmic side. Cell junction, focal adhesion. Cell projection, lamellipodium. Cytoplasm, cell cortex. Nucleus. Note=Interaction with NPHP1 induces the membrane-association of the kinase. Colocalizes with integrins at the cell periphery.
