Polymerase delta-interacting protein 3 (Poldip3)

Is involved in regulation of translation. Is preferentially associated with CBC-bound spliced mRNA-protein complexes throughout the pioneer round of mRNA translation.

Contributes to enhanced translational efficiency of spliced over nonspliced mRNAs. Recruits triggered ribosomal protein S6 kinase beta-1 I/RPS6KB1 to newly synthesized mRNA.
