General annotation (Comments)

Function	Negative regulator of PAK1. It has been suggested that the lost of CRIPAK in breast tumors might contribute to hormonal independence. Ref.2
Subunit structure	Interacts with PAK1. Ref.2
Subcellular location	Cytoplasm. Membrane. Nucleus. Note: Translocated to the nuclear compartment upon hormonal treatment by estrogen. Ref.2
Tissue specificity	Widely expressed with a highest espression observed in trachea, prostate and adrenal glands. Expressed in many cancer cell lines including breast cancer cells. Ref.2
Induction	Up-regulated by estrogen. Ref.2
