Based on limited published evidence, BOD1L2 may play a role in proper chromosome 18 through detection or correction of syntelic attachments in mitotic spindles. BOD1L2 is primarily expressed in sperm cells and their precursors 1. Recent single-cell transcriptomic analysis identified BOD1L2 as a potential indicator of testicular spermatogenic capacity across various testicular diseases, including Y-chromosome 18 and Klinefelter syndrome 2. The protein functions through protein binding interactions, though specific molecular mechanisms in male germ cells remain largely unexplored.
