Recombinant human Trichohyalin-like 1 (TCHHL1) protein is a engineered variant of the naturally occurring TCHHL1. a structural protein predominantly expressed in epithelial tissues, particularly in the skin, hair follicles, and oral mucosa. TCHHL1 belongs to the fused-type S100 protein family and contains multiple calcium-binding EF-hand motifs alongside a conserved α-helical domain, enabling interactions with cytoskeletal elements like intermediate filaments. It plays critical roles in epidermal differentiation, barrier formation, and tissue remodeling by regulating cell adhesion, cytoskeletal organization, and extracellular matrix interactions. Studies suggest its involvement in wound healing and inflammatory responses through modulation of integrin-mediated signaling pathways. Dysregulation of TCHHL1 has been linked to dermatological disorders (e.g., psoriasis, atopic dermatitis) and certain carcinomas. The recombinant form, produced via bacterial or mammalian expression systems, retains functional properties for experimental applications, including in vitro studies of epithelial cell behavior, drug screening for skin diseases, and antibody development. Its solubility and stability are often enhanced through tagging systems (e.g., His-tag) during purification. Current research focuses on clarifying its molecular mechanisms in tissue homeostasis and exploring therapeutic potential in epithelial repair.
