Summary: Enables histone H3K4 methyltransferase activity. Acts upstream of or within several processes, including ovarian follicle development; ovulation; and regulation of gene expression. Predicted to be located in nucleus. Predicted to be part of MLL1/2 complex. Is expressed in several structures, including alimentary system; inner cell mass; nervous system; sensory organ; and urinary system. Human ortholog(s) of this gene implicated in autosomal dominant intellectual developmental disorder; colorectal adenocarcinoma; dystonia 28, childhood-onset; and hepatocellular carcinoma. Orthologous to human KMT2B (lysine methyltransferase 2B). [provided by Alliance of Genome Resources, Dec 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
