PFAM accession number:PF16294
Interpro abstract (IPR032552):

The RSB motif on the Acinus (also known as Acin1) protein is the core around which the ASAP complex is built. The apoptosis and splicing-associated protein complex, ASAP, is made up of three proteins, SAP18 (Sin3-associated protein of 18 kDa), RNA-binding protein S1 (RNPS1) and apoptotic chromatin inducer in the nucleus (Acinus). The ASAP complex appears to be an assembly of proteins at the interface between transcription, splicing and nonsense-mediated mRNA decay (NMD), acting as a hub in the network of protein-interactions that regulate gene-expression [(PUBMED:22388736)].

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