HMCN1 (Hemicentin-1) is a large extracellular matrix protein belonging to the immunoglobulin (Ig) superfamily, encoded by the HMCN1 gene in humans. It plays a critical role in maintaining tissue integrity and cellular adhesion, particularly in elastic tissues such as skin, blood vessels, and the eye. Structurally, HMCN1 contains multiple Ig-like domains, epidermal growth factor (EGF)-like repeats, and a von Willebrand factor type D (VWFD) domain, which mediate interactions with other extracellular components and cell surface receptors. Its function is closely associated with fibrillin-rich microfibrils, contributing to the organization and stability of extracellular matrices.
Recombinant HMCN1 protein is engineered using expression systems (e.g., mammalian or insect cells) to produce purified, biologically active forms of the protein for research. It serves as a vital tool for studying cell-matrix interactions, tissue remodeling, and pathologies linked to HMCN1 dysregulation. Mutations in HMCN1 are implicated in age-related macular degeneration (AMD), cutis laxa, and other connective tissue disorders, making the recombinant protein valuable for elucidating disease mechanisms. Researchers also use it to investigate HMCN1’s role in cell migration, inflammatory responses, and angiogenesis, particularly in contexts like cancer metastasis or wound healing. Quality-controlled batches ensure consistency in binding assays, structural studies, and in vitro models of extracellular matrix dynamics. By enabling targeted manipulation of HMCN1 pathways, this recombinant protein supports therapeutic development, including potential treatments for fibrosis or degenerative diseases.
