ID A2A8U2; PN Transmembrane protein 201; GN Tmem201; OS 10090; SL Nucleus Position: SL-0178; SL Nucleus Position: SL-0179; SL Nucleus Position: SL-0182; SL Comments: [Isoform 2]: Nucleus inner membrane {ECO:0000250|UniProtKB:Q5SNT2}; Multi-pass membrane protein {ECO:0000250|UniProtKB:Q5SNT2}. Note=The C-terminal of isoform 2 is located on the nucleoplasmic side. During interphase, isoform 2 is distributed in the inner nuclear membrane and during mitosis, it is found in the ER but it also localizes to the polar regions of the mitotic spindle (By similarity). {ECO:0000250|UniProtKB:Q5SNT2}. DR UNIPROT: A2A8U2; DR UNIPROT: Q3U5F3; DR UNIPROT: Q6GQS9; DR UNIPROT: Q8BNY3; DR Pfam: PF10476; DR Pfam: PF09779; DE Function: Involved in nuclear movement during fibroblast polarization and migration (PubMed:22349700). May recruit Ran GTPase to the nuclear periphery (By similarity). {ECO:0000250|UniProtKB:Q5SNT2, ECO:0000269|PubMed:22349700}. [Isoform 2]: May define a distinct membrane domain in the vicinity of the mitotic spindle. Involved in the organization of the nuclear envelope implicating EMD, SUN1 and A-type lamina. {ECO:0000250|UniProtKB:Q5SNT2}. [Isoform 3]: Proposed to be involved in actin-dependent nuclear movement; via SUN2 associates with transmembrane actin- associated nuclear (TAN) lines which are bound to F-actin cables and couple the nucleus to retrograde actin flow. {ECO:0000305|PubMed:22349700}.
