 73-166 2.34e-31

RPA2_DBD_D: A subfamily of OB folds corresponding to the OB fold of the central ssDNA-binding domain (DBD)-D of human RPA2 (also called RPA32). RPA2 is a subunit of Replication protein A (RPA). RPA is a nuclear ssDNA-binding protein (SSB) which appears to be involved in all aspects of DNA metabolism including replication, recombination, and repair. RPA also mediates specific interactions of various nuclear proteins. In animals, plants, and fungi, RPA is a heterotrimer with subunits of 70KDa (RPA1), 32kDa (RPA2), and 14 KDa (RPA3). The major DNA binding activity of RPA is associated with RPA1 DBD-A and DBD-B; RPA2 DBD-D is a weak ssDNA-binding domain. RPA2 DBD-D is also involved in trimerization. The ssDNA binding mechanism is believed to be multistep and to involve conformational change. N-terminal to human RPA2 DBD-D is a domain containing all the known phosphorylation sites of RPA. Human RPA2 is phosphorylated in a cell cycle dependent manner in response to DNA damage. RPA2 interacts physically with menin; the gene encoding menin is a tumor suppressor gene disrupted in multiple endocrine neoplasia type I. This subfamily also includes RPA2 from Cryptosporidium parvum (CpRPA2). CpRPA2 is an SSB, which can be phosphorylated by DNA-PK in vitro.

OB-fold nucleic acid binding domain; This family contains OB-fold domains that bind to nucleic acids. The family includes the anti-codon binding domain of lysyl, aspartyl, and asparaginyl -tRNA synthetases (See pfam00152). Aminoacyl-tRNA synthetases catalyze the addition of an amino acid to the appropriate tRNA molecule EC:6.1.1.-. This family also includes part of RecG helicase involved in DNA repair. Replication factor A is a hetero-trimeric complex, that contains a subunit in this family. This domain is also found at the C-terminus of bacterial DNA polymerase III alpha chain.
