Regulates the processing of the mir-60 microRNA (miRNA), which in turn negatively regulates the expression of the transcription factor zip-10 (PubMed:29664006). Does not affect the splicing of zip-10 (PubMed:29664006). Ubiquitously expressed. RNAi-mediated knockdown results in up-regulation of the transcription factor zip-10 and its downstream target asp-17. Belongs to the ISY1 family.
