The core KH domain is accompanied by additional alpha-helix and beta-sheet motifs at the C terminus. This entry includes proteins involved in pre-mRNA splicing such as KH domain-containing BBP from fungi, KH homology domain-containing protein 4 (KHDC4, also known as BLOM7) and splicing factor 1 (SF1) from animals, and homologues from plants, including RIK. KHDC4 interacts with the PRP19C/Prp19 complex/NTC/Nineteen complex which is part of the spliceosome. It binds preferentially RNA with A/C rich sequences and poly-C stretches. Branchpoint binding proteins (BBP) from fungi and its mammalian homologue SF1 are required for pre-spliceosome formation [1-5].

Quaking-dimer is a helix-turn-helix dimer with an additional helix in the turn region. Dimerisation is required for adequate RNA-binding. Quaking is a prototypical member of the STAR (signal transducer and activator of RNA) protein family, which plays key roles in post-transcriptional gene regulation by controlling mRNA translation, stability and splicing [1]. STAR_dimer is the homodimerisation domain, Qua1 of the STAR domain of a series of proteins referred to as STAR/GSG, or Signal Transduction and Activation of RNA/GRP33, Sam68, GLD-1 family. These are conserved in higher eukaryotes and are RNA-binding transcriptional regulators. The STAR domain is a KH domain flanked by two homologous regions, Qua1 and Qua2. Qua1, this family, is the homodimerisation domain, and the KH plus Qua2 is the RNA-binding region [2].
