Recombinant human LUC7L protein is a genetically engineered version of the LUC7-like (LUC7L) protein, a conserved component of the spliceosome involved in pre-mRNA splicing. The native LUC7L, encoded by the *LUC7L* gene in humans, contains a zinc finger domain and is implicated in RNA binding and splice site recognition during mRNA processing. It plays roles in maintaining splicing fidelity and regulating alternative splicing events linked to cellular processes like transcription and DNA repair. Dysregulation of LUC7L has been associated with cancers, including acute myeloid leukemia (AML), where chromosomal translocations involving LUC7L may disrupt splicing machinery.
The recombinant form is typically expressed in *E. coli* or mammalian cell systems, enabling large-scale production for functional studies. Its recombinant nature allows epitope tagging (e.g., His-tag, FLAG-tag) for purification and detection. Research on recombinant LUC7L focuses on elucidating its structural and mechanistic roles in splicing, interactions with spliceosomal components (e.g., U1 snRNP), and potential disease-related mutations. Additionally, it serves as a tool to study aberrant splicing in pathologies or to develop splice-modulating therapies. Its conserved homology with yeast LUC7 underscores its evolutionary importance in RNA processing. Applications span molecular biology, cancer research, and drug discovery targeting splicing defects.
