Characteristics

The long noncoding RNA (lncRNA) LINC00266-1 encodes a 71-amino acid peptide.The peptide mainly interacts with the RNA-binding proteins, including the m6A reader IGF2BP1, and is thus named "RNA-binding regulatory peptide" (RBRP). [1].

Function

The oncopeptide RBRP encoded by LINC00266-1 is a regulatory subunit of m6A readers and strengthens m6A recognition on the target RNAs by the m6A reader to exert its oncogenic functions. [1].

Regulation

RBRP binds to IGF2BP1 and strengthens m6A recognition by IGF2BP1 on RNAs, such as c-Myc mRNA, to increase the mRNA stability and expression of c-Myc, thereby promoting tumorigenesis.[1]
