Recombinant human LHX2 protein is a engineered version of the LIM-homeodomain transcription factor LHX2. produced using recombinant DNA technology in laboratory systems such as *E. coli* or mammalian cell lines. LHX2 belongs to the LIM-homeobox family of proteins, characterized by two N-terminal LIM domains (zinc-finger motifs mediating protein-protein interactions) and a C-terminal homeodomain for DNA binding. It plays critical roles in embryonic development, particularly in neural patterning, eye morphogenesis, cortical layer formation, and hematopoietic stem cell maintenance. Studies in mice show that LHX2 knockout leads to severe developmental defects, including abnormal brain structure, failed eye development, and hematopoietic failure.
The recombinant LHX2 protein enables researchers to study its molecular functions, such as DNA binding specificity, transcriptional regulation, and interactions with cofactors like LDB1. It is widely used in *in vitro* assays, cell culture studies, and animal models to explore its role in tissue-specific gene expression, stem cell self-renewal, and differentiation. Recently, LHX2 has garnered attention in regenerative medicine and oncology due to its dual role in maintaining stem cell pluripotency and its aberrant expression in certain cancers. Recombinant LHX2 also serves as a potential therapeutic candidate for neuroregeneration or hematological disorders. However, challenges remain in understanding its context-dependent regulatory networks and post-translational modifications that modulate its activity.
