The Scd6-like Sm domain is found in Scd6p from S. cerevisiae, Rap55 from the newt Pleurodeles walt, and its orthologs from fungi, animals, plants and apicomplexans . The domain is also found in Dcp3p and the human EDC3/FLJ21128 protein where it is fused to the the Rossmanoid YjeF-N domain [1,2]. In addition both EDC3 and Scd6p are found fused to the FDF domain [1,2].
The Lsm14 N-terminal domain is a type of LSM domain found in Lsm14 proteins (also known as Rap55) [PUBMED:17074753, PUBMED:18723115] and in the Saccharomyces cerevisiae homologue Scd6 [PUBMED:15225602]. The domain is also found in the human EDC3 protein (enhancer of mRNA-decapping protein 3) where it is fused to the the Rossmanoid YjeF-N domain [PUBMED:15257761]. In addition, both EDC3 and Scd6 are found fused to the FDF domain [PUBMED:15225602, PUBMED:15257761].
