Summary
{"type": "root", "children": [{"type": "p", "children": [{"type": "t", "text": "\n ADAD2 is a testis‐specific, adenosine deaminase domain–containing protein that, despite its structural similarity to RNA editing enzymes, lacks catalytic activity and plays a crucial regulatory role during spermatogenesis.
