Abstract
Copy-DNA clones covering the complete coding sequence of human Elongation Factor-17 mRNA have been isolated and characterized. The expression of Elongation Factor-1 in a variety of cell lines and a number of tissues shows a large increase in Elongation Factor-1γ mRNA going from tissue to cultured cells (20-fold). Messenger-RNA levels for Elongation Factor-17α, -1β and -Iγ increase in parallel suggesting coordinate regulation of the expression of these genes. Oncogenic transformation in vitro does not strongly affect Elongation Factor-1 mRNA levels.
