| Type | developmental stage | Description | Detected at low levels from birth to 3 days post partum, thereafter the expression level increases from 5 days post partum to adult. In spermatocytes, shows punctate localization along chromosome axes specifically in early meiotic prophase I cells. Foci start to appear from the leptotene stage, reach their greatest number in the zygotene stage, persist until the early pachytene stage, and finally disappear in the late pachytene stage (PubMed:30760716). |
