sentence: Importantly , these three genes encode for functionally different proteins , and thus are likely to be regulated by different processes : CCAR1 ( Cell Division Cycle And Apoptosis Regulator 1 ) encodes for a protein that acts as a signal transductor , HNRNPDL ( Heterogeneous Nuclear Ribonucleoprotein D Like ) encodes for an RNA binding protein that complexes with heterogeneous nuclear RNA and SRSF6 ( Serine / Arginine-Rich Splicing Factor 6 ) encodes one member of the SR protein family and is a splicing regulator .
