  Domain Name: RPA2_OBF_family
RPA2_OBF_family: A family of oligonucleotide binding (OB) folds with similarity to the OB fold of the single strand (ss) DNA-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). RPA contains six OB folds, which are involved in ssDNA binding and in trimerization. The ssDNA binding mechanism is believed to be multistep and to involve conformational change. This family also includes OB folds similar to those found in Escherichia coli SSB, the wedge domain of E. coli RecG (a branched-DNA-specific helicase), E. coli ssDNA specific exodeoxyribonuclease VII large subunit, Pyrococcus abyssi DNA polymerase II (Pol II) small subunit, Sulfolobus solfataricus SSB, and Bacillus subtilis YhaM (a 3'-to-5'exoribonuclease). It also includes the OB folds of breast cancer susceptibility gene 2 protein (BRCA2), Oxytricha nova telomere end binding protein (TEBP), Saccharomyces cerevisiae telomere-binding protein (Cdc13), and human protection of telomeres 1 protein (POT1).

Tips:
 If you've navigated here from a protein, hovering over a position on the weblogo will display the corresponding protein position for that domain position.

 The histograms below the weblogo indicate mutations found on the domain. Red is for disease (OMIM) and blue is for SNPs.

 Functional Features are displayed as orange boxes under the histograms. You can choose which features are displayed in the box below.
