Proteins

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 name
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 gene
5 MLL fused at exon 6 with the 3 end of almost the entire LARG; LARG is oriented in a 5 to 3direction, like MLL
Fusion protein
excludes the NH2- PDZ domain of LARG, and includes most of LARG, from the Lsc homology (LH) domain to COOH
