pfam16274: Qua1 (This model is not part of the current CDD release)
Qua1 domain
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. 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.
