Structure of PTB RRM1(41-163) bound to an RNA stemloop containing a structured loop derived from viral internal ribosomal entry site RNA

Structural highlights

2n3o is a 2 chain structure with sequence from Homo sapiens and Synthetic construct. Full experimental information is available from OCA. For a guided tour on the structure components use FirstGlance.

Function

PTBP1_HUMAN Plays a role in pre-mRNA splicing and in the regulation of alternative splicing events. Activates exon skipping of its own pre-mRNA during muscle cell differentiation. Binds to the polypyrimidine tract of introns. May promote RNA looping when bound to two separate polypyrimidine tracts in the same pre-mRNA. May promote the binding of U2 snRNP to pre-mRNA. Cooperates with RAVER1 to modulate switching between mutually exclusive exons during maturation of the TPM1 pre-mRNA. Represses the splicing of MAPT/Tau exon 10.^[1] ^[2] ^[3] ^[4] ^[5]
