RNA recognition motif (RRM) found in yeast sporulation-specific protein 2 (Ssp2) and similar protein
This subfamily corresponds to the RRM of the lineage specific yeast sporulation-specific protein 2 (Ssp2) and similar proteins. Ssp2 is encoded by a sporulation-specific gene necessary for outer spore wall assembly in the yeast Saccharomyces cerevisiae. It localizes to the spore wall and may play an important role after meiosis II and during spore wall formation. Ssp2 contains one RNA recognition motif (RRM), also termed RBD (RNA binding domain) or RNP (ribonucleoprotein domain).
