[5][6] The protein encoded by this gene binds to the intronic cluster of RNA regulatory elements, downstream control sequence (DCS).

It is implicated in controlling the assembly of other splicing-regulatory proteins.

This protein is very similar to the polypyrimidine tract-binding protein PTBP1 but it is expressed primarily in the brain.
