Research on the BLM helicase in cells suggests it may have a complex role, with some studies indicating it can regulate certain signaling pathways and be targeted in specific malignancies, while others link it to genetic diseases and replication stress. The BLM helicase appears to be involved in various cellular processes, including the response to replicative stress and the regulation of recombination. Its functions and interactions with other factors, such as WRN, are being investigated to understand its role in human cells and its potential relationship to disease.
