Genes affected

KMT2E (HGNC:18541): (lysine methyltransferase 2E (inactive)) This gene is a member of the myeloid/lymphoid or mixed-lineage leukemia (MLL) family and encodes a protein with an N-terminal PHD zinc finger and a central SET domain. Overexpression of the protein inhibits cell cycle progression. Alternate transcriptional splice variants have been characterized. [provided by RefSeq, Jul 2008]

SRPK2 (HGNC:11306): (SRSF protein kinase 2) Enables ATP binding activity; magnesium ion binding activity; and protein serine/threonine kinase activity. Involved in several processes, including nucleic acid metabolic process; peptidyl-serine phosphorylation; and regulation of viral genome replication. Located in chromatin; cytosol; and nuclear lumen.
