Positive control of sporulation-specific genes by the IME1 and IME2 products in Saccharomyces cerevisiae.

abstract：:The interleukin-2 (IL-2) receptor (IL-2R) consists of three distinct subunits (alpha, beta, and gamma c) and regulates proliferation of T lymphocytes. Intracellular signalling results from ligand-mediated heterodimerization of the cytoplasmic domains of the beta and gamma c chains. To identify the residues of gamma c ...

abstract：:3'-end processing of nucleus-encoded mRNAs includes the addition of a poly(A) tail that is important for translation initiation. Since the vast majority of chloroplast mRNAs acquire their 3' termini by processing yet are not polyadenylated, we asked whether 3' end maturation plays a role in chloroplast translation. A ...
