Summary

LMO3 (LIM domain only 3, HGNC:6643) is a protein-coding gene on chromosome 12p12.3, encoding LIM domain only protein 3 (Q8TAP4).

The protein encoded by this gene belongs to the rhombotin family of cysteine-rich LIM domain oncogenes. This gene is predominantly expressed in the brain. Related family members, LMO1 and LMO2 on chromosome 11, have been reported to be involved in chromosomal translocations in T-cell leukemia. Many alternatively spliced transcript variants have been found for this gene.
