The function of RAVER1 (ribonucleoprotein, PTB binding 1, ENSG00000161847) is as follows. Cooperates with PTBP1 to modulate regulated alternative splicing events. Promotes exon skipping. Cooperates with PTBP1 to modulate switching between mutually exclusive exons during maturation of the TPM1 pre-mRNA (By similarity). .
