Krieg PA, Varnum SM, Wormington WM, Melton DA. 1989. The mRNA encoding elongation factor 1-alpha (EF-1 alpha) is a major transcript at the midblastula transition in Xenopus. Developmental biology. 133(1):93-100. Pubmed: 2707491


A Xenopus laevis gastrula cDNA library has been screened in order to identify sequences that are expressed early in development. We find that the mRNA encoding translation elongation factor 1-alpha (EF-1 alpha) is synthesized in very large amounts in the early embryo. Transcription of EF-1 alpha mRNA commences at the midblastula transition (MBT), and new EF-1 alpha protein is synthesized very soon after this, as determined by the association of EF-1 alpha mRNA with polysomes. The nucleotide sequence of a full-length EF-1 alpha cDNA clone and the deduced amino acid sequence of Xenopus EF-1 alpha protein are presented.

Doug Melton is pursuing a cure for type 1 diabetes. His lab studies the developmental biology of the pancreas, using that information to grow and develop pancreatic cells (islets of Langerhans). In parallel, they investigate ways to protect beta cells from autoimmune attack.
