DAZL (Deleted in Azoospermia Like) is an RNA-binding protein essential for gametogenesis in both males and females, playing critical roles in reproductive development and cellular regulation 1. The protein contains one RNA recognition motif and one DAZ repeat, specifically binding to GUU triplets in the 3' untranslated regions of target mRNAs to regulate translation 12. DAZL functions through multiple mechanisms including translational activation, mRNA stabilization, and enhancement of microRNA processing by directly binding precursor miRNAs and increasing DICER cleavage activity 13. Beyond its established role in germ cell development, DAZL regulates cell proliferation by promoting miRNA maturation, which silences proliferation regulators like TRIM71 3. The gene is clinically significant in reproductive medicine, as complete deletion of the related DAZ cluster shows strong association with male infertility (OR=13.23) 4, while DAZL mutations are implicated in primary ovarian insufficiency 5. Importantly, DAZL expression serves as a marker of germline commitment during human development, with its induction indicating successful progression from primordial germ cell specification 6. Additionally, DAZL dysregulation has been observed in glioblastoma, where it contributes to tumorigenicity and stemness, suggesting broader roles beyond reproductive biology 7.
