Vinculin (VCL) is an actin filament-binding protein primarily functioning in cell-matrix and cell-cell adhesion through interactions with the E-cadherin complex and focal adhesions. VCL regulates cell-surface E-cadherin expression and potentiates mechanosensing, playing important roles in cell morphology and locomotion. Functionally, VCL modulates cytoskeletal organization and cell-cell junction assembly at adherens junctions and costameres. Clinically, VCL variants are associated with dilated cardiomyopathy (DCM) and familial hypertrophic cardiomyopathy. VCL was classified as having moderate evidence for DCM pathogenesis among 51 curated genes, likely to emerge as stronger evidence with additional data 1. Beyond cardiac disease, VCL plays roles in multiple pathological contexts: it is aberrantly spliced in RBM10-loss metastatic thyroid cancers, where VCL exon inclusion increases cell velocity 2, and the VCL pathway is a hallmark of SARS-CoV-2 Omicron infection contributing to lung inflammation and vascular leakage 3. Additionally, phthalate exposure significantly downregulates VCL expression in endometrial cells, suggesting potential impacts on cell adhesion 4, and VCL is identified as a hub gene in atherosclerotic plaque instability 5. These findings establish VCL as a critical regulator of adhesion-dependent processes with therapeutic relevance across cardiovascular, infectious, and oncological diseases.
