bicistronic gene

[ANNE GEORGE]

Has anyone heard about 2 messages transcribed from the same gene. The reading 
frames for the two proteins are different. this is in the eukaryotic system. The 
northern hybridization shows me 2 distinct bands. help needed very badly. is there 
any reference available.
Thanks in advance
