Facts about Activated CDC42 kinase 1.
Binds to both poly- and mono-ubiquitin and modulates ligand-induced degradation of EGFR, thereby leading to the accumulation of EGFR at the limiting membrane of early endosomes. Downstream effector of CDC42 that mediates CDC42-dependent cell migration via phosphorylation of BCAR1.

The Tyr-284 phosphorylated form shows a significant increase in expression in breast cancers during the progressive stages i.e. normal to hyperplasia (ADH), ductal carcinoma in situ (DCIS), invasive ductal carcinoma (IDC) and lymph node metastatic (LNMM) stages. It also shows a significant increase in expression in prostate cancers during the progressive stages.
Cell membrane. Nucleus. Endosome. Cell junction, adherens junction. Cytoplasmic vesicle membrane; Peripheral membrane protein; Cytoplasmic side. Cytoplasmic vesicle, clathrin-coated vesicle. Membrane, clathrin-coated pit. Cytoplasm, perinuclear region. The Tyr-284 phosphorylated form is found both in the membrane and nucleus. Colocalizes with EGFR on endosomes. Nuclear translocation is CDC42-dependent.
