B [auth A]PF09169BRCA2, helical (BRCA-2_helical)BRCA2, helicalMembers of this family adopt a helical structure, consisting of a four-helix cluster core (alpha 1, alpha 8, alpha 9, alpha 10) and two successive beta-hairpins (beta 1 to beta 4). An approx. 50-amino acid segment that contains four short helices (al ...Domain
