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].
