Transcription 9501 bp mRNA; 4634 bp open reading frame


Description the gene encodes a guanine nucleotide exchange factor; 1544 amino acids; NH2- PDZ domain, Lsc homology (LH) domain, bipartite nuclear localization signal, Dbl homology (DH) domain, and a pleckstrin homology (PH) domain -COOH
Expression wide (leukocytes, spleen, prostate, testis, ovary, small intestine, colon, thymus)
Function PDZ domains are involved in protein-protein interactions in transmembrane signaling pathways; LH domains bind G proteins; nuclear localization signals are implicated in translocation of proteins from the cytoplasm to the nucleus; DH domains are responsible for the nucleotide exchange activity of guanine nucleotide exchange (GEF) toward Rho GTPases, PH domains function in membrane localization; Rho GEF are regulators of GTPases, and have oncogenic properties
Homology member of the family of Rho GEF factors, like dbl, vav, tiam, and BCR

Implicated in

Entity acute non lymphocytic leukemia (AML) with apparently normal cromosomes 11 --> KMT2A- LARG
Note poorly defined: only 1 case to date, a 38 yr old male patient with occupational exposure; M4-AML; CR; death unrelated to the leukemia
Cytogenetics the case was 51,XY,+8,+19,+3mar; the interstitial deletion at 11q23 resulting in MLL-LARG fusion cannot be seen at the chromosome level
Hybrid/Mutated Gene 5' MLL fused at exon 6 with the 3' end of almost the entire LARG; LARG is oriented in a 5' to 3'direction, like MLL
Abnormal Protein excludes the NH2- PDZ domain of LARG, and includes most of LARG, from the Lsc homology (LH) domain to COOH


Identification of a gene at 11q23 encoding a guanine nucleotide exchange factor: evidence for its fusion with MLL in acute myeloid leukemia.
