背景信息

LRRC3B (Leucine-Rich Repeat-Containing Protein 3B) is a member of the leucine-rich repeat (LRR) superfamily, characterized by tandem repeats of 20–30 amino acids rich in leucine residues. These proteins are involved in diverse cellular processes, including cell adhesion, signaling, and immune responses. LRRC3B, specifically, is a relatively understudied protein, though emerging research suggests its potential role in tumor suppression and cellular regulation. It is encoded by the *LRRC3B* gene located on human chromosome 3q25.1 and is expressed in various tissues, with higher levels observed in the brain, testes, and certain epithelial cells.

Structurally, LRRC3B contains multiple LRR domains, which typically mediate protein-protein or protein-ligand interactions, hinting at its involvement in intercellular communication or signaling pathways. Studies have linked LRRC3B to cancer biology, particularly in gliomas and other solid tumors. For instance, reduced LRRC3B expression has been correlated with poor prognosis in glioma patients, suggesting it may act as a tumor suppressor by modulating cell proliferation, migration, or apoptosis. Epigenetic silencing via promoter hypermethylation has been proposed as a mechanism for its downregulation in malignancies.

Recombinant LRRC3B protein is engineered using expression systems like *E. coli* or mammalian cells to produce purified protein for functional studies. This tool enables researchers to investigate its interactions with binding partners, signaling roles (e.g., potential crosstalk with pathways like Wnt or Notch), and therapeutic applications. Additionally, recombinant LRRC3B may serve as an antigen for antibody development or a candidate for exploring its diagnostic or therapeutic potential in cancers. Further research is needed to fully elucidate its molecular mechanisms and translational relevance.
