Abstract: The invention provides methods for isolating cell-type specific mRNAs by selectively isolating ribosomes or proteins that bind mRNA in a cell type specific manner, and, thereby, the mRNA hound to the ribosomes or proteins that bind mRNA. Ribosomes, which are riboprotein complexes, bind mRNA that is being actively translated in cells. According to the methods of the invention, cells are engineered to express a molecularly tagged ribosomal protein or protein that binds mRNA by introducing into the cell a nucleic acid comprising a nucleotide sequence encoding a ribosomal protein or protein that binds mRNA fused to a nucleotide sequence encoding a peptide tag. The tagged ribosome or mRNA binding protein can then be isolated, along with the mRNA bound to the tagged ribosome or mRNA binding protein, and the mRNA isolated and further used for gene expression analysis.

Abstract: Methods and compositions are provided for translational profiling and molecular phenotyping of specific tissues, cells and cell subtypes of interest. The methods provided herein facilitate the analysis of gene expression in the selected subset present within a heterogeneous sample.

Abstract: The present invention provides a method for tethering peptides, including neuropeptides and peptide toxins, including naturally occurring and mutant or altered peptides, to a surface, including the cell surface. The tethered peptides are not naturally tethered or attached to a surface, including a cell surface, or through a cell membrane. The tethered neuropeptides and toxins are useful in the targeted modulation of synaptic transmission and for regulation of cellular physiology, including neurophysiology, in vitro, ex vivo and in vivo. The use of these tethered peptides, including neuropeptides and toxins, in therapeutic and diagnostic methods and screening assays is also provided.

Abstract: A simple method for modifying genes in a recombination deficient host cell is disclosed. Such modifications include generating insertions, deletions, substitutions, and/or point mutations at any chosen site in the independent origin based cloning vector. The modified gene is contained in an independent origin based cloning vector that is used to introduce a modified heterologous gene into a cell. Such a modified vector may be used in the production of a germline transmitted transgenic animal, or in gene targeting protocols in eukaryotic cells. In particular, high throughput methodology is provided for generating the modified the independent origin based cloning vectors of the present invention.
