LIM2 recombinant protein, also known as Lens Intrinsic Membrane Protein 2 or LIM2. is a structural protein primarily expressed in the eye lens. Encoded by the *LIM2* gene in humans, it belongs to the LIM family of proteins characterized by cysteine-rich zinc-binding domains. LIM2 is a transmembrane protein critical for maintaining lens transparency and fiber cell organization. It plays a vital role in lens development and homeostasis by facilitating cell-cell adhesion, regulating ion transport, and ensuring proper differentiation of lens epithelial cells into elongated fiber cells.
Mutations in the *LIM2* gene are linked to autosomal recessive congenital cataracts, highlighting its importance in lens integrity. Recombinant LIM2 protein is engineered using heterologous expression systems (e.g., *E. coli* or mammalian cells) to study its molecular interactions, structural properties, and pathological mechanisms in vitro. Researchers utilize purified LIM2 to investigate its role in cataract formation, screen potential therapeutic compounds, or develop antibodies for diagnostic applications. Its recombinant form retains functional domains, enabling studies on protein-protein interactions with cytoskeletal components (e.g., filensin) or signaling molecules involved in lens opacity. Current research also explores its potential as a biomarker for lens disorders and its utility in tissue engineering for lens regeneration strategies.
