Technical Data
CCK4 (Colon Carcinoma Kinase 4, CCK-4, Inactive Tyrosine-protein Kinase 7, Protein-tyrosine Kinase 7, PTK7, Pseudo Tyrosine Kinase Receptor 7, Tyrosine-protein Kinase-like 7)
CCK4 (colon carcinoma kinase 4, also known as PTK7) is a receptor tyrosine kinase (RTK) involved in colon carcinoma development and/or proliferation. Similar to the RTK HER3, CCK4 contains a catalytically inactive tyrosine kinase domain, suggesting a potential tumor-characteristic role as a signal amplifier or modulator for an as yet unidentified kinase-competent partner.

Suitable for use in Western Blot. Other applications have not been tested.
