PTBP1 [ENSP00000349428]
polypyrimidine tract binding protein 1; Plays a role in pre-mRNA splicing. Binds to the polypyrimidine tract of introns. 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
FUS [ENSP00000254108]
fused in sarcoma; Binds both single-stranded and double-stranded DNA and promotes ATP-independent annealing of complementary single- stranded DNAs and D-loop formation in superhelical double-stranded DNA. May play a role in maintenance of genomic integrity
