Although SNORD56B is not explicitly discussed in these abstracts, as a small nucleolar RNA typically residing in the nucleus, it is conceivable that SNORD56B may participate in the fine‐tuning of these processes—perhaps by contributing to rRNA modification or by indirectly influencing the regulatory pathways mediated by proteins like ZRANB2 and ZNF265.
