FUSION GENES
DNA/RNA

Grey: exon 1a, green: exon 1b; blue: exon 2ab; yellow : exon 2g; brown: exons 3,4, 5, 6. Arrows: transcription start sites. CpG: location of CpG islands. RASSF1A and RASSF1B start with exon 1a and 1b respectively. The second exon (2ab) is common to both forms. Exon 2g is the first exon of RASSF1C and is present in this transcript only.
Description
the genomic size of the gene is about 7.6 kb.
Transcription
At least three alternative transcripts were identified (A, B and C) that originate from alternative splicing and promoter usage. Exons 3 to 6 are common to all forms. Transcript A has two 5 exons (designated 1a and 2ab), this cDNA is 1,873 bp (ORF: 340 amino acids). RASSF1B first exon is designated 1b and is different from RASSF1A. Exon two is 2ab as in transcript A. cDNA size: 1,664 bp. Transcript RASSF1C first exon is designated 2g, cDNA size 1700 bp (ORF 270 amino acids).
Pseudogene
no known pseudogenes.
Proteins

Schematic representation of RASSF1 protein variants, as deduced from the transcripts.
Description
The carboxy terminus of RASSF1A shows about 55% identity to the mouse protein Nore1 and the rat protein Maxp1, both are Ras effector proteins (Nore1 was shown to interact in vivo with Ras upon receptor activation in a GTP-dependent manner). RASSF1A N terminus has high homology with a domain known as protein kinase C conserved region 1 domain (a cysteine-rich diacylglycerol/phorbol ester binding domain). RASSF1B most likely is constituted only of the Ras association domain.
Expression
RASSF1A and RASSF1C are expressed in heart, brain, placenta, lung, liver, skeletal muscle, kidney, pancreas, spleen, thymus, prostate, testis, small intestine, colon, peripheral blood leukocytes. RASSF1B is expressed predominantly in cells of hematopoietic origin.
Localisation
not determined.
Function
RASSF1 binds Ras in a GTP-dependent manner and may serve as the effector that mediates Ras apoptotic effects. Alternatively, it may sequester RAS proteins thereby regulating the availability of these proteins for signaling.
Mutations
Note
single nucleotide polymorphism (SNP) in exon 1a: AAG (Lys21)/CAG (Gln21).
Somatic
Mutations were rarely found. In non small cell lung cancer four were found: GAC (Asp129) to GAG (Glu129); ATT (Ile135) to ACT (Thr135); CGG (Arg257) to CAG (Gln257); GCC (Ala336) to ACC (Thr336).
Implicated in
Entity name
clear cell renal carcinoma and papillary renal carcinoma; lung cancer; ovarian cancer; prostate cancer, gastric adenocarcinoma; bladder carcinoma; nasopharingeal carcinoma; breast cancer.
Note
The mechanism of inactivation of this tumor suppressor consists in promoter hypermethylation. The gene promoter was found hypermetylated in 90 % of primary kidney tumors and 40 % of lung tumors. Hypermethylation and loss of transcription were causally related. Hypermethylation occurs in variable percentage in other tumors and indicate a role for this gene in malignant progression (62 % of bladder carcinoma; 49 % of breast tumors; 40 % of ovarian tumors; 12 % of colon cancer).
