LITERATURE
a 2.7 kb 5'-flanking region of the human BHMT gene cloned between MluI and SmaI sites of a promoterless pGL-3-basic vector creating the recombinant plasmid -2698/+33 BHMT-LUC, expression in HepG2 cells
expressed in COS-1 cells and in Escherichia coli
-
expressed in Escherichia coli BL21(DE3) (coexpression of human recombinant betaine-homocysteine S-methyltransferase)
-
expressed in Hep-G2 cell
glutathione S-transferase-BHMT fusion protein is expressed in HEK-293, T98G, A-10, MCF-7, H-1299, C2C12, and NIH-3T3 cells
-
impossible to express BHMT2 in mammalian cells, protein aggregates after bacterial expression. BHMT2 is rapidly degraded in a rabbit reticulocyte lysate, but it can be stabilized by cotransfection of COS-1 cells with BHMT and, after cotransfection, it coprecipitates with BHMT
-
transiently expressed in HepG2-cells and primary mouse hepatocytes
