**Background of Recombinant Human KIAA1991 Protein**
The KIAA1991 gene, also known as *CCDC138* (Coiled-Coil Domain Containing 138), encodes a protein with conserved structural domains, including coiled-coil regions, suggesting roles in protein-protein interactions or structural organization. Initially identified through large-scale cDNA sequencing projects, its precise biological function remains under investigation. Studies indicate potential involvement in cellular processes such as ciliogenesis, intracellular trafficking, or transcriptional regulation, though mechanistic details are limited.
Recombinant human KIAA1991 protein is produced via heterologous expression systems (e.g., *E. coli* or mammalian cells) to enable functional and structural studies. Its recombinant form allows researchers to explore interactions with binding partners, subcellular localization, and contributions to pathways like Wnt/β-catenin signaling, with emerging links to diseases such as cancer or ciliopathies. Tissue expression profiling shows enrichment in brain, testis, and kidney, hinting at tissue-specific roles.
While KIAA1991 remains undercharacterized, recombinant protein tools are critical for clarifying its molecular functions, potential therapeutic relevance, and association with pathological conditions. Ongoing research aims to resolve its 3D structure and define its role in cellular homeostasis or disease mechanisms.
