RAD54L2 is a member of the RAD54 family of DNA repair proteins, which play critical roles in homologous recombination (HR), a key pathway for repairing DNA double-strand breaks (DSBs) and maintaining genomic stability. RAD54L2 shares structural and functional similarities with its paralogs, RAD54L (RAD54A) and RAD54B, but exhibits distinct expression patterns and biological contexts. Unlike RAD54L, which is ubiquitously expressed in somatic cells, RAD54L2 is primarily expressed in germ cells and is implicated in meiotic recombination, a process essential for proper chromosome segregation during gamete formation.
Structurally, RAD54L2 belongs to the SWI2/SNF2 superfamily of ATP-dependent chromatin remodelers. It contains conserved helicase-like domains that enable DNA binding, ATP hydrolysis, and chromatin remodeling activities. These functions facilitate the displacement of recombination proteins, such as RAD51. from repaired DNA strands and promote the migration of Holliday junctions—a critical step in HR. RAD54L2’s ATPase activity is thought to drive conformational changes in DNA, enhancing the efficiency and fidelity of strand exchange and resolution during recombination.
Studies suggest RAD54L2 is particularly vital in meiosis, where it collaborates with other HR proteins to ensure accurate repair of programmed DSBs, thereby preventing chromosomal aberrations and infertility. Its dysfunction has been linked to meiotic defects, genomic instability, and potential associations with reproductive disorders. While less characterized in somatic cells, emerging evidence hints at roles in cancer biology, with altered RAD54L2 expression observed in certain malignancies, though its precise oncogenic or tumor-suppressive mechanisms remain under investigation.
Overall, RAD54L2 represents a specialized HR mediator with unique contributions to germ cell development and genome integrity, highlighting its importance in both basic biology and disease contexts. Further research is needed to fully elucidate its regulatory networks and therapeutic potential. (Word count: 398)
