The Williams-Beuren syndrome chromosomal region 1 (WBSCR1) protein, encoded by the *WBSCR1* gene within the 7q11.23 chromosomal region, is implicated in Williams-Beuren syndrome (WBS), a rare neurodevelopmental disorder caused by heterozygous deletions of approximately 26 genes. WBSCR1 is a ubiquitously expressed nuclear protein evolutionarily conserved across eukaryotes. Structurally, it contains a sterile alpha motif (SAM) domain, which mediates protein-protein interactions, and an intrinsically disordered region linked to dynamic molecular functions.
Although its precise molecular mechanisms remain incompletely characterized, WBSCR1 is proposed to act as a transcriptional regulator, interacting with chromatin-modifying complexes to influence epigenetic states and gene expression. Studies suggest roles in cell cycle regulation, DNA repair, and mRNA splicing. Notably, it binds host cell factor C1 (HCFC1), a transcriptional coactivator, potentially modulating neural or metabolic pathways.
WBS-related deletions of *WBSCR1* correlate with hypersociability, cardiovascular defects, and cognitive deficits observed in patients, though its specific contribution to these phenotypes is unclear. Recombinant human WBSCR1 protein, typically expressed in *E. coli* or mammalian systems, enables functional studies, including protein interaction mapping, enzymatic assays, and structural analysis. Current research focuses on clarifying its role in chromatin remodeling, neurological development, and metabolic homeostasis, with therapeutic implications for WBS and related disorders. Its multifunctional nature positions WBSCR1 as a nexus for integrating transcriptional and genomic stability pathways.
