Genes affected

SRSF12 (HGNC:21220): (serine and arginine rich splicing factor 12) Enables RNA binding activity. Involved in mRNA 5'-splice site recognition and regulation of alternative mRNA splicing, via spliceosome. Predicted to be located in nucleoplasm. Predicted to be active in cytoplasm and nuclear speck. [provided by Alliance of Genome Resources, Apr 2022]

SRSF12 links:

PM20D2 (HGNC:21408): (peptidase M20 domain containing 2) Enables dipeptidase activity and identical protein binding activity. Acts upstream of or within proteolysis and regulation of cellular protein metabolic process. Located in nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]
