DNA polymerase alpha-primase synthesizes short RNA-DNA primers on the lagging strand during DNA synthesis. It is a heterotetramer composed of two polymerase subunits (DNApol-α180 and DNApol-α73) and two primase subunits (DNApol-α50 and DNApol-α60). DNApol-α180 and DNApol-α50 encode the DNA polymerase and RNA primase catalytic activities, respectively, while DNApol-α73 and DNApol-α60 encode the regulatory subunits. (Adapted from PMID:30005324.)
