Recombinant human LOC283951 protein is a product of the LOC283951 gene, currently annotated as a poorly characterized protein in public databases such as NCBI and UniProt. Its biological function remains largely undefined, though computational analyses suggest potential involvement in cellular processes like nucleic acid binding or enzymatic regulation due to conserved structural motifs. The gene is located on chromosome 9 (9q34.3 in humans) and shares weak homology with certain nucleotide-metabolizing enzymes across species, though experimental validation is lacking.
Interest in this protein has emerged from disease association studies. GWAS and transcriptomic data link LOC283951 dysregulation to neurological disorders and epithelial cancers, particularly glioblastoma and colorectal adenocarcinoma. However, mechanistic insights are scarce. Recombinant versions are typically expressed in E. coli or mammalian systems (e.g., HEK293 cells) with affinity tags (His-tag, FLAG) to facilitate purification and antibody development.
Current research focuses on elucidating its interactome through pull-down assays and crystallography attempts to resolve its 3D structure. A unique feature is its predicted intrinsically disordered regions, suggesting potential roles in liquid-liquid phase separation or scaffold formation. Despite being classified as a "long non-coding RNA neighbor" gene, proteomic studies confirm its translation into a ~25 kDa protein in multiple tissues. Its low basal expression in most cells and stress-induced upregulation in hypoxia models hint at context-dependent functions. Further characterization could reveal therapeutic relevance in precision oncology or neurodegeneration.
