MUCL1 (Mucin-like protein 1), also known as small breast epithelial mucin or SBEM, is a glycoprotein encoded by the *MUCL1* gene located on human chromosome 12q24.13. Structurally, it belongs to the mucin family, characterized by a central tandem repeat domain rich in serine and threonine residues that facilitate O-glycosylation. Unlike classical mucins, MUCL1 lacks a transmembrane domain and is secreted extracellularly, playing roles in cell signaling, lubrication, and epithelial barrier maintenance. It is predominantly expressed in glandular tissues, including the breast, salivary glands, and prostate.
Research highlights MUCL1 as a potential biomarker in oncology, particularly in breast cancer, where its overexpression correlates with tumor aggressiveness, metastasis, and poor prognosis. Its secretion into bodily fluids, such as saliva and serum, has spurred interest in non-invasive diagnostic applications. Additionally, MUCL1 may influence tumor microenvironment interactions, including immune evasion, though its precise molecular mechanisms remain under investigation.
Recombinant MUCL1 protein is engineered using expression systems like mammalian cells or *E. coli*, often tagged for purification (e.g., His-tag). This tool enables functional studies, antibody development, and drug screening. Challenges include maintaining post-translational modifications critical for its biological activity, necessitating optimized expression platforms. Current studies focus on elucidating its role in cancer progression and therapeutic targeting, positioning MUCL1 as a promising candidate for diagnostic and therapeutic innovation.
