Background Information

SIPA1 (Signal-induced proliferation-associated protein 1) is also named as SPA1, p130 SPA-1 and GTPase-activating protein Spa-1. SIPA1, a GTPase activating protein, was discovered in proliferating lymphocytes as mitogen-induced nuclear protein. SIPA1 promotes catalyzation of hydrolyze Rap1GTP/GDP and is known to be a negative regulator of Ras-related protein, which transduces the signals for various cellular functions, including development, cellular proliferation, and cellular adhesion (PMID:28237246). Transcription of fibronectin 1, which is crucial for cell junction and migration of triple-negative breast cancer (TNBC) cells, was regulated by SIPA1 in a DBR-dependent manner. SIPA1 was highly expressed in metastatic TNBC. SIPA1 served as a TF, promoting TNBC migration, invasion, and metastasis (PMID: 37500797).
