RBM39linker

RBM39linker
PFAM accession number:PF15519
Interpro abstract (IPR029123):

This entry represents a conserved linker between the second and the third RRM domain in human RBM39 (also known as CAPER) protein and other RNA splicing proteins. CAPER is a transcriptional coactivator of activating protein-1 (AP-1) and estrogen receptors (ERs). This linker was implicated in interactions with ERalpha and ERbeta [ (PUBMED:11704680) ]. Preliminary results from JCSG suggest that this is a structured domain with a well defined fold.

This is a PFAM domain. For full annotation and more information, please see the PFAM entry RBM39linker
