Kinetics and regulation of the tyrosine phosphorylation of epidermal growth factor receptor in intact A431 cells.

abstract：:A strong block to the elongation of nascent RNA transcripts by RNA polymerase II occurs in the 5' part of the mammalian c-fos proto-oncogene. In addition to the control of initiation, this mechanism contributes to transcriptional regulation of the gene. In vitro transcription experiments using nuclear extracts and pur...
