**Recombinant human POU3F4 protein** is a synthesized form of the transcription factor encoded by the *POU3F4* gene, which belongs to the POU-domain protein family. This protein plays critical roles in embryonic development, particularly in the formation and differentiation of the inner ear, neural tissues, and skeletal structures. It regulates gene expression by binding to specific DNA sequences via its conserved POU domain, enabling interactions with co-regulators to modulate cellular processes like proliferation and differentiation.
Mutations in the *POU3F4* gene are strongly associated with X-linked recessive hearing loss (DFNX2), a non-syndromic form of deafness characterized by cochlear malformations. Recombinant POU3F4 is produced using biotechnological systems (e.g., bacterial or mammalian expression systems) for functional studies, enabling researchers to investigate its role in auditory development and disease mechanisms. It serves as a tool to explore DNA-binding properties, transcriptional regulation, and potential therapeutic strategies, such as gene therapy for hearing disorders. Additionally, studies using recombinant POU3F4 may shed light on its interactions with signaling pathways (e.g., Wnt, FGF) during tissue development. Its application extends to disease modeling, drug screening, and molecular diagnostics for congenital hearing impairments.
