RASAL3 (RAS Protein Activator Like 3) is a member of the RAS GTPase-activating protein (RASAL) family, which plays a regulatory role in RAS signaling pathways. As a GTPase-activating protein (GAP), RASAL3 accelerates the hydrolysis of active RAS-GTP to inactive RAS-GDP, thereby suppressing RAS-mediated signal transduction. This activity positions RASAL3 as a potential tumor suppressor, given the oncogenic consequences of RAS hyperactivation in cell proliferation, differentiation, and survival. Structurally, RASAL3 contains conserved domains critical for its function, including a pleckstrin homology (PH) domain for membrane targeting and a catalytic GAP domain.
Recent studies suggest RASAL3's involvement in diverse physiological and pathological processes. It regulates immune cell functions, such as T-cell activation and macrophage polarization, and is implicated in autoimmune disorders. In cancer, reduced RASAL3 expression has been linked to tumor progression in certain contexts, though its role appears context-dependent, with pro-tumorigenic effects reported in specific malignancies. Additionally, RASAL3 may influence neurological processes, including synaptic plasticity. The recombinant human RASAL3 protein, produced via heterologous expression systems, serves as a key tool for studying RAS pathway dynamics, protein interactions, and therapeutic targeting. Ongoing research aims to clarify its dual roles in tumor suppression and oncogenesis, as well as its potential as a biomarker or therapeutic target in RAS-driven diseases.
