DNA primase is the polymerase that synthesises small RNA primers for the Okazaki fragments made during discontinuous DNA replication. DNA primase is a heterodimer of two subunits, the small subunit Pri1 (48 kDa in yeast), and the large subunit Pri2 (58 kDa in the yeast S. cerevisiae) [1]. The large subunit of DNA primase forms interactions with the small subunit and the structure implicates that it is not directly involved in catalysis, but plays roles in correctly positioning the primase/DNA complex, and in the transfer of RNA to DNA polymerase [4]. This entry represents the C-terminal alpha helical domain.	Domain

This entry represents the OB domain of DNA polymerase alpha subunit B [1-4]. B subunits of DNA polymerases stabilize the catalytic subunit, play a role in regulation of the DNA synthesis in a cell cycle-dependent manner and act as scaffolds mediating interactions with other components of the replication machinery [1-4].
