Human RRM domains

    Novel RNA-binding domains added to Pfam database based on JCSG structures

    Determination of a novel protein structure often enables adding a new protein domain annotation to public databases. Two out of six RRM domains annotated in Pfam database were added to RRM clan based on JCSG structures: RRM_5 and RRM_6 domains based on JCSG structures 3s01 and 3s7r, respectively. Both structures were joint targets of JCSG, Partnership for Stem Cell Biology and Partnership for T-Cell Biology.

    Novel RNA-binding domains in Human

    These proteins contain putative novel RNA-binding domains which were found by remote homology recognition method FFAS (and often confirmed by other methods) during DUF Annotation Jamboree  meeting. They are not yet included in public annotations in Pfam and Uniprot databases.


    The first two domain based on this analysis was added to PFAM as DUF4463 (PF14703), seeded by a putative RRM domain from human transmembrane protein Q9P1W3 and DND1_DSRM (PF14709), seeded by a C-terminal domain in human dead end protein 1 (DND1_HUMAN). The latter is a new member of a double strand RNA binding domain  clan (DSRM, CL0196)
