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). Interacts with CHMP4B, but not with VPS25 (By similarity). Interacts with LEMD2 (via C-terminus) (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.
