Microtubule-associated protein that exhibits cell cycle-dependent localization and can inhibit cell proliferation and migration. Observed in the nucleus and at the perinuclear region during interphase, but localizes at the mitotic spindle and midbody at metaphase. A significant fraction of MARVELD1 translocates to the plasma membrane during anaphase or upon microtubule depolymerization (By similarity). Widely expressed in normal tissues. Down-regulated in multiple primary tumors. Down-regulated in primary multiple tumors derived from ovary, vulva, uterus, cervix, breast, testis, kidney bladder and liver. The reduced expression is owing to DNA methylation and could be reversed by pharmacologic demethylation (PubMed:19364627).
