KMT2B (Lysine Methyltransferase 2B) is a Protein Coding gene. Diseases associated with KMT2B include Dystonia 28, Childhood-Onset and Spindle Cell Sarcoma. Among its related pathways are Chromatin organization and Lysine degradation. KMT2B encodes a protein which contains multiple domains including a CXXC zinc finger, three PHD zinc fingers, two FY-rich domains, and a SET (suppressor of variegation, enhancer of zeste, and trithorax) domain. The SET domain is a conserved C-terminal domain that characterizes proteins of the MLL (mixed-lineage leukemia) family. KMT2B is ubiquitously expressed in adult tissues. It is also amplified in solid tumor cell lines, and may be involved in human cancer. Two alternatively spliced transcript variants encoding distinct isoforms have been reported for KMT2B, however, the full length nature of the shorter transcript is not known.
