An immunological and biochemical comparison of 67 kDa calcimedin and 67 kDa calelectrin.
The 67 kDa calcimedin is a Ca2+-binding protein isolated from several muscle tissues. A recent report [Morse & Moore (1988) Biochem. J. 251, 171-174] indicated that the 67 kDa calcimedin is distinct from 67 kDa calelectrin, which is purified from various non-muscle cells. In the present study we have purified the 67 kDa protein from bovine aorta (i.e. 67 kDa calcimedin) and liver (i.e. 67 kDa c...
متن کاملInteractions between PrP(c) and other ligands with the 37-kDa/67-kDa laminin receptor.
The 37-kDa/67 kDa laminin receptor (LRP/LR) represents a multifunctional protein. It is a receptor for viruses such as Dengue viruses, Alphaviruses and Adeno-associated viruses (AAV), as well as the cellular prion protein (PrPc) and infectious prions. Furthermore, the 37-kDa/67-kDa LRP/LR plays fundamental roles in basic cell biological processes such as cell adhesion and cell growth and acts a...
متن کاملThe 37/67 kDa laminin receptor (LR) inhibitor, NSC47924, affects 37/67 kDa LR cell surface localization and interaction with the cellular prion protein.
The 37/67 kDa laminin receptor (LR) is a non-integrin protein, which binds both laminin-1 of the extracellular matrix and prion proteins, that hold a central role in prion diseases. The 37/67 kDa LR has been identified as interactor for the prion protein (PrP(C)) and to be required for pathological PrP (PrP(Sc)) propagation in scrapie-infected neuronal cells, leading to the possibility that 37/...
متن کاملThe 37-kDa/67-kDa laminin receptor acts as a receptor for infectious prions and is inhibited by polysulfated glycanes.
BACKGROUND Recently, we showed that the 37-kDa/67-kDa laminin receptor (LRP/LR) acts as the receptor of the cellular prion protein. METHODS For the present study, we investigated the binding of the murine scrapie prion protein (moPrP27-30) to baby hamster kidney (BHK) cells, using the Semliki Forest virus system. RESULTS The enhanced binding of moPrP27-30 to BHK cells expressing moLRP::FLAG...
متن کامل67 kDa laminin receptor: structure, function and role in cancer and infection.
The 67 kDa high affinity laminin receptor (67LR) is a non integrin cell surface receptor for the extracellular matrix whose expression is increased in neoplastic cells and directly correlates with an enhanced invasive and metastatic potential. 67LR derives from homo- or hetero-dimerization of a 37 kDa cytosolic precursor (37LRP), by fatty acid acylation. Interestingly, 37LRP is a multifunctiona...
