Family: HkH motif-containing C2H2 finger

putative dsRNA-specific zinc finger with a helix-kink-helix (HkH) motif; the kink results from the incompatibility of the cation-coordinating H-x5-H motif with a regular alpha-helix and contributes to RNA recognition

Lineage:

1. Root: scop
2. Class: Small proteins [56992]
   Usually dominated by metal ligand, heme, and/or disulfide bridges
3. Fold: beta-beta-alpha zinc fingers [57666]
   simple fold, consisting of the N-terminal beta-hairpin and C-terminal alpha-helical region; each part provides two zinc-coordinating residues with the observed sequences including C2H2, C2HC and CHHC
4. Superfamily: beta-beta-alpha zinc fingers [57667]
   uperfamily
5. Family: HkH motif-containing C2H2 finger [111436]
   putative dsRNA-specific zinc finger with a helix-kink-helix (HkH) motif; the kink results from the incompatibility of the cation-coordinating H-x5-H motif with a regular alpha-helix and contributes to RNA recognition
