背景信息

**SPARCL1 (Secreted Protein Acidic and Rich in Cysteine-Like 1)** is a member of the SPARC family of matricellular proteins, which regulate cell-matrix interactions and modulate cellular processes such as adhesion, proliferation, and differentiation. Structurally, SPARCL1 contains conserved domains typical of SPARC proteins, including an acidic N-terminal region, a cysteine-rich follistatin-like domain, and a calcium-binding EF-hand motif. These domains enable SPARCL1 to interact with extracellular matrix (ECM) components, growth factors, and cell surface receptors, influencing tissue remodeling and signaling pathways.

SPARCL1 is broadly expressed in developing and adult tissues, particularly in vascular, neural, and epithelial systems. It plays roles in tissue repair, angiogenesis, and neuronal development. However, its dysregulation is implicated in pathologies, including cancer and neurodegenerative disorders. In tumors, SPARCL1 often acts as a tumor suppressor by inhibiting proliferation, migration, and metastasis, though its role can be context-dependent. In neurodegenerative conditions like Alzheimer’s disease, SPARCL1 may modulate amyloid-beta aggregation and neuroinflammation.

**Recombinant SPARCL1 protein** is engineered for research and therapeutic applications. Produced via mammalian or bacterial expression systems, it retains bioactivity for *in vitro* and *in vivo* studies. Researchers use it to investigate SPARCL1’s mechanisms in ECM organization, cell signaling, and disease models. Therapeutically, it holds potential for promoting tissue regeneration or targeting pathways in cancers and neurological disorders. Despite progress, challenges remain in understanding its context-specific functions and optimizing delivery strategies for clinical use.
