ESCRT-III-like protein required to recruit the ESCRT-III complex to the nuclear envelope during late anaphase(PubMed:26040712). Together with SPAST, the ESCRT-III complex promotes nuclear envelope sealing and mitotic spindle disassembly during late anaphase(PubMed:26040712). Plays a role in the endosomal sorting pathway(PubMed:16856878).
