A. Shiratori et al., ASSIGNMENT OF THE 49-KDA (PRIM1) AND 58-KDA (PRIM2A AND PRIM2B) SUBUNIT GENES OF THE HUMAN DNA PRIMASE TO CHROMOSOME BANDS 1Q44 AND 6P11.1-P12, Genomics, 28(2), 1995, pp. 350-353
DNA primase is an essential replication protein that catalyzes the syn
thesis of oligoribonucleotide primers. DNA primase, consisting of two
subunits (p49 and p58), plays a key role in both the initiation of DNA
replication and the synthesis of Okazaki fragments for lagging strand
synthesis. We mapped the locations of human chromosomes of the genes
coding for both subunits [p49 (PRIM1) and p58 (PRIM2)] by PCR amplific
ation using DNAs of a panel of somatic hybrids, to chromosomes 1 and 6
, respectively. The PRIM1 gene was mapped to 1q44, and two PRIM2 loci
(PRIM2A and PRIM2B) were detected at 6p11.1-p12 by fluorescence in sit
u hybridization using several genomic DNA probes. (C) 1995 Academic Pr
