Multifunctional proteins having M-CSF activity and at least one other bioactivity not found together in a single naturally occuring molecule are described. These multifunctional M-CSF proteins can be produced by the expression of fused genes which are also described. These multifunctional M-CSF proteins have increased therapeutic potential.

Multifunctional M-CSF proteins and genes encoding therefor

Disclosed are the entire coding sequence for unprocessed and mature trichosanthin from Trichosanthes kirilowii, and primers derived from this coding sequence for use in obtaining the coding sequences of ribosome inactivating proteins which have regions of amino acid sequence identical to those of trichosanthin. Also disclosed is a recombinant trichosanthin protein produced from the coding sequence, and the mature protein with amino-terminal and/or carboxy-terminal extensions.

Recombinant trichosanthin and coding sequence

Disclosed are the entire protein and nucleic acid coding sequences for unprocessed and mature trichosanthin protein from Trichosanthes kirilowii. A recombinant trichosanthin protein produced from the coding sequence, and the trichosanthin protein with amino-terminal and/or carboxy-terminal extensions are also described. Primers derived from the coding sequence are disclosed for use in obtaining the coding sequences of ribosome-inactivating-proteins which have regions of amino acid sequence identical to those of trichosanthin. Further, a multigene family of ribosome-inactivating-protein encoding genes of Trichosanthes kirilowii is also described.
