CX9C is the first half of a twin Cx9C motif in eukaryotic proteins. The function of this motif is to import nuclear-encoded mitochondrial intermembrane-space-proteins into the IMS (intermembrane space), as these latter lack a mitochondrial targeting sequence. The Cx9C proteins have a disulfide-bonded alpha-hairpin conformation. Cx9C-containing proteins are thus putative substrates for the Mia40-dependent thiol-disulfide exchange mechanism that carries out an oxidative folding process resulting in the proteins being trapped in the IMS [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.

RsgA (also known as EngC and YjeQ) represents a protein family whose members are broadly conserved in bacteria and are indispensable for growth. The GTPase domain of RsgA is very similar to several P-loop GTPases, but differs in having a circular permutation of the GTPase structure described by a G4-G1-G3 pattern [1].
