Cadherin 4 (CDH4) is a single pass transmembrane cadherin encoded by CDH4 gene. This protein localizes to plasma membrane of multiple cell populations derived from neural and epithelial tissue origins. CDH4 contains multiple extracellular cadherin repeat domains, a single transmembrane helix and a conserved intracellular cytoplasmic tail. Extracellular cadherin repeats extend outward into intercellular space, while cytoplasmic tail resides within cellular cytoplasm. The proper folding of its extracellular domains relies on calcium ion coordination at defined binding sites distributed across each repeat unit. CDH4 exhibits tissue‑restricted expression patterns, and its protein abundance varies across distinct developmental stages. Newly synthesized CDH4 polypeptide undergoes intracellular processing events within secretory compartments before trafficking toward cell surface, and only correctly folded molecules can achieve stable plasma membrane localization.
CDH4 can mediate calcium-dependent homologous cell adhesion. Its extracellular cadherin repeat domain can specifically recognize homologous CDH4 molecules on the surface of adjacent cells, and calcium ions can stabilize the rigid conformation of extracellular structure and ensure the stability of cell recognition and binding. The intracellular tail of CDH4 can recruit a variety of cytoplasmic adaptor proteins, assemble them to form a multi-molecular complex, and physically couple the cell membrane adhesion cluster with the cytoskeleton structure. This molecular connection method can strengthen the contact sites between cells and maintain the spatial arrangement and overall stability of multicellular tissue structure.The extracellular sequence characteristics of different cadherin family members are significantly different, which determines their unique homologous binding preference. Other cadherin subtypes cannot completely reproduce the extracellular binding specificity of CDH4. CDH4 sequence mutation or abnormal cell membrane expression level will destroy the normal assembly of intercellular adhesion complex, interfere with the stable recognition and adhesion connection between adjacent cells, and finally affect the orderly construction and steady maintenance of tissue structure.

The biological functions of CDH4 are focused on calcium‑dependent homophilic cell‑cell recognition, adhesion complex assembly and cytoskeleton linkage:
Creative Biolabs offers purified CDH4 membrane samples via standardized preparation workflows, including full‑length CDH4 constructs and isolated extracellular structural variants. Isolated extracellular fragments may not support complete homophilic adhesion and cytoskeleton adaptor recruitment related behaviours, while full‑length constructs may be suited for cadherin‑mediated cell‑cell recognition and molecular complex assembly related research. All samples receive routine quality screening, and functional relevant observation may only be carried out with full‑length samples under simulated membrane environments. All sample batches follow unified processing standards to maintain consistent structural features for comparative laboratory analysis across separate test groups.

Creative Biolabs provides adjustable CDH4 expression cell models with varied expression levels, applicable to transmembrane cadherin structural characteristic observation and calcium‑dependent cell‑cell adhesion related research. Sample evaluation includes sustained target expression detection and preliminary intermolecular interaction associated observation, which can support comparative analysis of adhesion‑associated behaviours under different expression statuses. These cell systems can be matched with diverse laboratory analysis schemes to observe changes of intermolecular contact efficiency under different target expression abundances.

Beyond catalog products, Creative Biolabs offers specialized custom services for CDH4 research:
CDH4 may function as a transmembrane cadherin and participate in calcium‑dependent homophilic cell‑cell adhesion and intracellular adhesion complex assembly.
CDH4 expression status may alter cell‑cell adhesion complex assembly, serving as a major regulatory mediator of cell‑cell recognition related biological processes.
No, all CDH4 related products and services are strictly for research use only, not intended for clinical related operations. All material designs and functional tests are only optimized for basic laboratory research scenarios, without matching clinical application standards.
Offerings include full‑length CDH4 membrane protein, target specific recombinant antibodies and adjustable expression cell research models, supporting calcium‑dependent cell‑cell adhesion molecular research.
Laboratory observation schemes may include cadherin‑mediated intermolecular contact tests to analyse molecule‑associated behaviours under simulated cellular environments.
