This domain, approximately 40 residues in length, is mainly found in KH-domain containing, RNA-binding, signal transduction-associated protein 1 from yeast to human [1]. It forms a homodimer composed of a perpendicular interaction of two helical hairpins, and the Qua1 domain is sufficient for homodimerization which is required for the regulation of alternative splicing [2].
