Proteins

Description

110 KD protein, 896 amino acids; major cytoplasmic vault protein; vaults are nucleoproteic complexes composed of the MVP associated with two high-molecular weight proteins p240 and p193 which surround a small 140 nucleotides RNA species

Expression

expressed in a variety of human tumor cell lines, the major part being multidrug resistant; expressed also in primary solid tumors, mainly colon carcinoma or ovarian carcinoma, as well as in hematopoietic cancers (myelodysplastic syndrome, acute myeloid or lymphoid leukemia, multiple myeloma); in normal tissues, LRP expression has a wide distribution, with particularly high levels in epithelial cells of the digestive tract

Localisation

cytoplasmic, in the cytosol, with a little fraction (approximately 5%) located in the nuclear membrane and nuclear pores

Function

vault are cytoplasmic organelles which mediate bidirectional nucleocytoplasmic transport of a wide range of substrates, including cytotoxic drugs; vaults would be involved both in vesicule and cytosolic transport of molecules

Homology

104 kD rat MVP

Entity name
implicated in induced multidrug-resistance to anticancer chemotherapy
Disease
it includes resistance to doxorubicin, vinca alkaloids, mitoxantrone and etoposide; the role of LRP by itself in multidrug-resistance is not completely clear because it is only a part of a nucleo-proteic complex involved in macromolecules transport; the introduction and expression of the LRP gene in cells by transfection does not confer a multidrug-resistance phenotype; overexpression of LRP has been associated with poor response to chemotherapy in various types of leukemia and in ovarian carcinoma, however the role of LRP as pronostic factor remains controversial; in multi-resistant cell lines, LRP amplification within a homogeneous staining region is exceptional
