A gizzard cDNA library was screened by the two-hybrid system using as bait the delta isoform of the catalytic subunit of protein phosphatase 1 (PP1delta). Among the proteins identified was a fragment of the polypyrimidine tract-binding protein-associated splicing factor (PSF) and for 242 residues was 97.1% identical to the human isoforms. Binding of PSF and PP1delta was confirmed by inhibition of phosphatase activity and by an overlay technique. The PP1delta binding site was contained in the N-terminal 82 residues of the PSF fragment. PSF may therefore act as a PP1 target molecule in the spliceosome.
