| abstractText | The identity of cDNA encoding beta 1,4 galactosyltransferase (EC 2.4.1.38) has been controversial, since two independent and unrelated cDNAs have been cloned (GTcDNA-1 and -2), both of which are thought to encode beta 1,4 galactosyltransferase. We have resolved this issue by examining the expression of the corresponding mRNAs in tissues possessing varying levels of galactosyltransferase activity. The expression of GTcDNA-1 parallels the level of galactosyltransferase activity assayed enzymatically, while the expression of GTcDNA-2 is unrelated to the level of enzyme activity, being virtually undetectable in tissues with abundant galactosyltransferase activity. GTcDNA-2, therefore, does not likely encode beta 1,4 galactosyltransferase, but rather, encodes a product that indirectly influences enzyme activity following cellular transfection. |
