**Background of Recombinant Human FAM81B Protein**
FAM81B (Family With Sequence Similarity 81 Member B) is a poorly characterized protein encoded by the *FAM81B* gene, which is highly conserved across vertebrates and predominantly expressed in the brain, particularly in neurons and synaptic regions. Emerging studies suggest its potential role in neurodevelopment and synaptic plasticity, though its precise molecular function remains unclear. Genomic analyses link *FAM81B* to neuropsychiatric disorders such as schizophrenia and autism spectrum disorder, highlighting its possible relevance in neural circuit formation or cognitive processes.
Recombinant human FAM81B protein is engineered using heterologous expression systems (e.g., *E. coli* or mammalian cells) to produce purified, functional protein for mechanistic studies. Its recombinant form enables exploration of its interactions with synaptic proteins, intracellular signaling pathways, or nucleic acids. Recent proteomic studies hint at its association with RNA-binding proteins or cytoskeletal regulators, suggesting roles in mRNA transport or dendritic spine dynamics.
Despite limited structural data, FAM81B’s conserved domains imply involvement in protein-protein or protein-nucleic acid interactions. Current research focuses on clarifying its physiological roles using knockout models and *in vitro* assays. Recombinant FAM81B also serves as a tool for antibody development, structural studies, and screening for therapeutic targets in neurodevelopmental disorders. Further investigations are needed to unravel its contribution to brain function and disease pathology.
