Target: Tricellulin (MARVELD2)

Andere Bezeichnung: MARVELD2

Hintergrund: MARVELD2 antibody detects MARVEL domain-containing protein 2, also known as Tricellulin, a tight junction-associated protein that maintains epithelial barrier integrity at tricellular junctions where three cells meet. MARVELD2 is essential for forming the barrier against paracellular diffusion of macromolecules, thereby preserving tissue polarity and homeostasis. The MARVELD2 antibody is widely used in epithelial biology and cell junction research to study tight junction architecture, permeability control, and barrier dysfunction.

MARVELD2 is encoded by the MARVELD2 gene located on human chromosome 5q13.1. The protein is approximately 558 amino acids long and contains four transmembrane segments with a cytoplasmic C-terminal tail. It localizes at tricellular tight junctions, distinct from bicellular tight junction proteins such as occludin and claudins. MARVELD2 interacts with angulin family proteins and zonula occludens proteins to anchor the tricellular junction complex to the actin cytoskeleton.

The MARVELD2 antibody detects a 65 kilodalton band by western blot and exhibits strong junctional staining along epithelial borders in immunofluorescence. MARVELD2 regulates diffusion barrier properties by sealing the tricellular junction core, ensuring that epithelial sheets restrict large solute movement. Loss of MARVELD2 disrupts paracellular sealing, resulting in barrier leakage and increased susceptibility to inflammation and infection.

Mutations in MARVELD2 cause autosomal recessive deafness (DFNB49) due to impaired tight junction formation in the cochlea, leading to hair cell degeneration and hearing loss. Altered expression is also associated with inflammatory bowel disease and cancer metastasis, where weakened epithelial integrity promotes tissue invasion and immune infiltration.

As a critical determinant of epithelial sealing and tissue organization, MARVELD2 serves as a biomarker for tight junction function and epithelial polarity. NSJ Bioreagents provides a validated MARVELD2 antibody optimized for its applications, supporting research into barrier formation, epithelial biology, and junctional signaling.
