    • Disclosed are useful constructs and methods for the expression of proteins using primary translation products that are processed within a recombinant host cell. Constructs comprising a single open reading frame (sORF) are described for protein expression including expression of multiple polypeptides. A primary translation product (a pro-protein or a polyprotein) contains polypeptides such as inteins or hedgehog family auto-processing domains, or variants thereof, inserted in frame between multiple protein subunits of interest. The primary product can also contain cleavage sequences such as other proteolytic cleavage or protease recognition sites, or signal peptides which contain recognition sequences for signal peptidases, separating at least two of the multiple protein subunits. The sequences of the inserted auto-processing polypeptides or cleavage sites can be manipulated to enhance the efficiency of expression of the separate multiple protein subunits. Also disclosed are independent aspects of conducting efficient expression, secretion, and/or multimeric assembly of proteins such as immunoglobulins. Where the polyprotein contains immunoglobulin heavy and light chain segments or fragments capable of antigen recognition, in an embodiment a selectable stoichiometric ratio is at least two copies of a light chain segment per heavy chain segment, with the result that the production of properly folded and assembled functional antibody is made. Modified signal peptides, including such from immunoglobulin light chains, are described.

    • Embodiments of the invention relate to vector constructs and methods for expression of polypeptides including multimeric products such as therapeutic antibodies. Particular constructs allow for the generation of expression products from a single open reading frame (sORF). An embodiment provides an isolated or purified expression vector for generating one or more recombinant protein products comprising a single open reading frame insert; said insert comprising a signal peptide nucleic acid sequence encoding a signal peptide; a first nucleic acid sequence encoding a first polypeptide; a first intervening nucleic acid sequence encoding a first protein cleavage site, wherein said first protein cleavage site is provided by an intein segment of a Ion protease gene of Pyrococcus or a klbA gene of Pyrococcus or Methanococcus, or a modified intein segment derived therefrom; and a second nucleic acid sequence encoding a second polypeptide. Certain embodiments of constructs and methods employ an intein segment of a Ion protease gene of Pyrococcus abyssi, Pyrococcus furiosus, or Pyrococcus horikoshii OT3; or an intein segment of a klbA gene of Pyrococcus abyssi, Pyrococcus furiosus, or Methanococcus jannaschir, or other intein segment.

    • Se describen construcciones y metodos utiles para la expresion de proteinas utilizando productos de traduccion primaria que son procesados dentro de una celula huesped recombinante. Las construcciones que comprenden una sola estructura de lectura abierta (sORF) se describen para la expresion de proteinas incluyendo expresion de polipeptidos multiples. Un producto de traduccion primaria (una proteina o poliproteina) contiene polipeptidos tales como inteinas o dominios de auto-procesamiento de la familia de erizos, o variantes de los mismos, insertadas en la estructura entre multiples subunidades de proteina de interes. El producto primario tambien puede contener secuencias de disociacion, tales como otros sitios de reconocimiento de proteasa o disociacion proteolitica, o peptidos de senal que contienen secuencias de reconocimiento para peptidasas de senal, que separa al menos dos de las multiples subunidades de proteina. Las secuencias de los polipeptidos de auto-procesamiento o sitios de disociacion insertados, pueden manipularse para mejorar la eficiencia de expresion de las subunidades de proteina multiple separadas. Tambien se describen aspectos independientes para llevar a cabo una expresion, secrecion, y/o ensamble de proteinas multimerico eficiente, tal como inmunoglobulinas. Cuando la poliproteina contiene segmentos de cadena pesada y ligera de inmunoglobulina o fragmentos con la capacidad de reconocimiento de antigenos, en una modalidad una proporcion estequiometrica seleccionable es de al menos dos copias de un segmento de cadena ligera por segmento de cadena pesada, obteniendo como resultado que se lleve a cabo la produccion del anticuerpo funcional doblado y ensamblado. Se describen peptidos de senal modificados, incluyendo los que proceden de cadenas ligeras de inmunoglobulina.
