ESCRT-III-like protein required to recruit the ESCRT-III complex to the nuclear envelope (NE) during late anaphase (By similarity). Together with SPAST, the ESCRT-III complex promotes NE sealing and mitotic spindle disassembly during late anaphase (By similarity). Recruited to the reforming NE during anaphase by LEMD2 (By similarity). Plays a role in the endosomal sorting pathway (By similarity). Diffused localization, with some punctate distribution, especially in the perinuclear area. Localizes to the reforming nuclear envelope on chromatin disks during late anaphase. Belongs to the SNF7 family.
