CASS4 (Cas Scaffolding Protein Family Member 4): CASS4 is a gene that encodes a scaffolding protein involved in integrin signaling and cell migration. It plays a key role in cytoskeleton reorganization, supporting cell movement and invasion. CASS4’s function in signaling pathways related to migration and its connection to the extracellular matrix make it important in cancer metastasis and immune cell activity.
