DNA Primase small subunit, also known by its gene name PRIM1, is a heterodimer that is composed of a small and large subunit. PRIM1 is 420 amino acids long and approximately 49kDa. The DNA Primase small subunit synthesizes RNA primers for the Okazaki fragments created during discontinuous DNA replication. Current research surrounding PRIM1 has shown a possible link with carcinomas, malaria, neuronitis, and osteosarcoma. DNA Primase small subunit has also been shown to interact with Histone cluster 1 H4/A, H4/B, H4/C, H4/D and H4/E in pathways such as DNA replication, DNA strand elongation, polymerase switching, and lagging strand synthesis.
