Abstract:
The regulation of developmental processes at the RNA level enables selective and rapid modulation of gene expression. Studies in model organisms revealed the essential contribution of the signal transduction and activation of RNA (STAR) family of RNA binding proteins to developmental processes. STAR proteins coordinate the proper timing of developmental events by delaying expression or altering the mRNA or protein levels of essential genes. Recent functional analysis of the Drosophila melanogaster STAR protein, Held Out Wing (HOW), in the context of embryonic development, provided insight into its mode of activity. Here, we describe HOW's activity in the temporal repression or elevation of gene expression that is essential for coordinating the correct timing of instructive signals.

Transcription
Transcription is the process of synthesizing RNA from a DNA sequence by RNA polymerase. It is the first step in producing a protein from a gene sequence. Additionally, many other proteins and regulatory sequences are involved in the proper synthesis of messenger RNA (mRNA). Regulation of transcription is responsible for the differentiation of all the different types of cells and often for the proper cellular response to environmental signals.
