Gene ID: 84456 | Gene type: protein coding

About L3MBTL3

Cytogenetic location: 6q23.1 Genomic coordinates (GRCh38): 6:130,018,581-130,141,438 (from NCBI)

This gene has 10 transcripts (splice variants), 169 orthologues and 18 paralogues. Ubiquitous expression in endometrium (RPKM 5.0), spleen (RPKM 4.6) and 24 other tissues.

Summary

This gene encodes a member of the malignant brain tumor (MBT) family of chromatin interacting transcriptional repressors. Members of this family function as methyl-lysine readers, which recognize methylated lysine residues on histone protein tails, and are associated with the repression of gene expression. The encoded protein may regulate hematopoiesis. Homozygous deletion of this gene has been observed in human patients with medulloblastoma. [provided by RefSeq, Oct 2016]
