FUSION GENES

DNA/RNA

Description

spans on a 35 kb genomic fragment; two exons separated by a large intron; small GTPase encoding gene

Transcription

2.2 kb mRNA; coding sequence: 575 bp, located in the second exon

Proteins

Description

191 amino acids; 21 kDa; contains a GTP binding motif, a GTPase activity site, and a membrane localisation signal (CAAX box) in the very C-term

Expression

restricted to the hemopoietic tissues

Localisation

plasmic membrane
