Recombinant Human FLJ38663 Protein

Recombinant human FLJ38663 protein is a genetically engineered protein derived from the FLJ38663 gene, a poorly characterized human gene located on chromosome X (Xq28). Initially identified through cDNA sequencing projects, FLJ38663 encodes a hypothetical protein with limited functional annotation in public databases. Its exact physiological role remains unclear, though bioinformatic analyses suggest it may contain conserved domains associated with transmembrane signaling or intracellular protein interactions. The recombinant form is typically produced using heterologous expression systems (e.g., E. coli or mammalian cells) to enable functional studies. Researchers utilize this purified protein primarily for antibody development, protein-protein interaction assays, and preliminary investigations into its potential involvement in cellular processes such as membrane trafficking or signal transduction. Current interest in FLJ38663 stems from genomic studies linking its chromosomal region to X-linked disorders and cancer biomarkers, though direct evidence connecting the protein to specific diseases is lacking. Its recombinant version serves as a critical tool for overcoming challenges in native protein purification and advancing molecular characterization efforts, bridging gaps in understanding understudied proteins within the human proteome.
