hnRNP Associated With Lethal Yellow Protein (RALY)

RALY containing a 16 amino acid in-frame insert in the variable region of the protein. Analysis of the corresponding region of the mouse Raly gene demonstrated that this novel protein isoform is also present in the mouse. Comparative analysis of RALY cDNA and EST sequences suggests the presence of additional alternatively processed RALY transcripts. As in the mouse, the human RALY gene is widely expressed as a 1.7-kb transcript. In infectious mononucleosis, anti-EBNA-1 antibodies are produced which cross-react with multiple normal human proteins. The cross-reactivity is due to anti-gly/ala antibodies that cross-react with host proteins containing configurations like those in the EBNA-1 repeat. One such antigen is RALY which is a member of the heterogeneous nuclear ribonucleoprotein gene family.
