This is an acidic sequence segment domain found in the splicing factor SYNCRIP (hnRNP Q) which is involved in viral replication, neural morphogenesis, modulation of circadian oscillation and the regulation of the cytidine deaminase APOBEC1. This domain is a self-folding globular domain with an all alpha-helix architecture with negatively charged surface areas. Additionally it contains a large hydrophobic cavity and a positively charged surface area as potential epitopes for inter-molecular interactions [1].

The RRM motif (a.k.a. RRM, RBD, or RNP domain) is probably diagnostic of an RNA binding protein. RRMs are found in a variety of RNA binding proteins, including various hnRNP proteins, proteins implicated in regulation of alternative splicing, and protein components of snRNPs. The motif also appears in a few single stranded DNA binding proteins. The RRM structure consists of four strands and two helices arranged in an alpha/beta sandwich, with a third helix present during RNA binding in some cases The C-terminal beta strand (4th strand) and final helix are hard to align and have been omitted in the SEED alignment The LA proteins (Swiss:P05455) have an N terminal rrm which is included in the seed. There is a second region towards the C terminus that has some features characteristic of a rrm but does not appear to have the important structural core of a rrm. The LA proteins (Swiss:P05455) are one of the main autoantigens in Systemic lupus erythematosus (SLE), an autoimmune disease.
