Recombinant human CHX10 protein, derived from the VSX2 gene, is a homeodomain transcription factor critical in vertebrate retinal development. CHX10 plays a pivotal role in regulating progenitor cell proliferation, differentiation, and maintenance of retinal bipolar cells. Mutations in CHX10 are linked to ocular disorders such as microphthalmia, anophthalmia, and coloboma, underscoring its importance in eye morphogenesis. Structurally, it contains a conserved homeodomain for DNA binding and a C-terminal domain for protein interactions.
Produced via recombinant DNA technology in systems like *E. coli* or mammalian cells, this engineered protein retains native functionality, enabling mechanistic studies of retinal development and disease pathogenesis. Researchers use it to investigate CHX10’s role in gene regulatory networks, its interactions with co-factors (e.g., transcriptional repressors), and its potential in restoring visual function in degenerative conditions. Additionally, recombinant CHX10 serves as a tool for screening therapeutic compounds targeting retinal disorders and optimizing gene-editing strategies. Its applications extend to stem cell research, aiding in the differentiation of retinal cell lineages for regenerative therapies. By providing a purified, bioactive form of CHX10. this recombinant protein accelerates both basic research and translational efforts in ophthalmology.
