| - 22. Helix-Loop-Helix Domain
- [In transcription regulators of cell cycle control, cell determination, and cell differentiation, the conserved HLH (Helix-Loop-Helix) Domain of 40-50 amino acids forms amphipathic helixes between a variable loop. HLHs typically mediate homo- or heterodimerization through interactions with self or other motifs to activate or inactivate trans-activating function. The N-helix often contains DNA-interacting basic residues; the C-helix typically contains characteristically spaced hydrophobic residues. An adjacent basic region of 15 amino acids in most HLH proteins binds to DNA. Basic (b)HLH proteins bind variants of the 'CANNTG' E-box. Proteins lacking the basic domain act as inhibitors, failing to bind DNA. bHLH proteins exhibit specific dimerization partner combinations. In calcium-binding proteins, certain invariant hydrophilic loop residues in the HLH motif bind calcium. (NCI) ( NCI )] (UMLS (NCI) C0206678) =Spatial Concept ;

- 7. Helicase SKI2W
- [Encoded by human SKIV2L Gene (SKI2 Helicase Family), 1246-aa 138-kDa Helicase SKI2W is a conserved DEAD box protein yeast SKI2 homologue containing a leucine zipper domain, motifs associated with RNA helicases, and ATPase activity that may be involved in antiviral activity by blocking translation of poly(A) deficient mRNAs. Conserved motif DEAD box RNA helicases are implicated in translation initiation, nuclear and mitochondrial splicing, and ribosome and spliceosome assembly. Rapid 3-prime-to-5-prime degradation of unstable mammalian mRNAs containing 3-prime UTR AU-rich elements (AREs) is mediated by the multisubunit exosome. ARE-binding proteins interact with the exosome and recruit it to ARE-containing RNAs, promoting their degradation. Helicase SKI2W is an exosome-associated factor.
