LIN54 is a key component of the LINC (LIN complex) multiprotein complex, which plays a critical role in chromatin binding and cell cycle regulation. Human LIN54 facilitates the stable association of the LINC complex with specific gene promoters, particularly those involved in cell cycle progression and differentiation. It contains a conserved CXC domain responsible for DNA binding and a LISE (LIN54. LIN9. ISY1) domain that mediates interactions with other LINC components, such as LIN9 and Rb (Retinoblastoma) protein. LIN54 is essential for the G1/S phase transition, where it cooperates with the Rb-E2F pathway to regulate gene expression, ensuring proper cell cycle control and preventing aberrant proliferation.
Recombinant human LIN54 protein is engineered for in vitro studies to dissect its molecular functions, structural features, and interactions. By expressing LIN54 in heterologous systems (e.g., bacteria or mammalian cells), researchers can purify the protein for assays exploring its DNA-binding specificity, role in chromatin remodeling, or partnerships with other LINC components. Studies using recombinant LIN54 have advanced understanding of its contribution to transcriptional regulation, replication licensing, and genomic stability. Dysregulation of LIN54 is implicated in cancers, as altered expression may disrupt cell cycle checkpoints. Research on recombinant LIN54 also supports drug discovery efforts targeting cell cycle-related diseases. Its structural and functional insights remain vital for unraveling mechanisms underlying development, differentiation, and oncogenesis.
