SL  Comments: Nucleus inner membrane {ECO:0000269|PubMed:19167377, ECO:0000269|PubMed:25946333}; Multi-pass membrane protein {ECO:0000255}; Nucleoplasmic side {ECO:0000269|PubMed:19167377}. Nucleus envelope {ECO:0000269|PubMed:19167377}. Note=Localization in the nuclear membrane is essential for its function. Colocalizes with lamins and banf1-a/b at the nuclear envelope. {ECO:0000269|PubMed:19167377, ECO:0000269|PubMed:25946333}.

DE  Function: In concert with ran, required for proper eye development (PubMed:25946333). May be involved in the expression of early eye marker genes (PubMed:19167377). Contributes to nuclear envelope stiffness in germ cells (By similarity). Required for fertility (By similarity). {ECO:0000250|UniProtKB:O14524, ECO:0000269|PubMed:19167377, ECO:0000269|PubMed:25946333}.
