About Ptbp1

Summary

Enables RNA binding activity. Involved in negative regulation of mRNA splicing, via spliceosome and negative regulation of neuron differentiation. Acts upstream of with a negative effect on gene expression. Acts upstream of or within neurogenesis and positive regulation of transcription by RNA polymerase II. Located in nucleus. Is expressed in several structures, including brain; genitourinary system; hemolymphoid system gland; liver; and sensory organ. Orthologous to human PTBP1 (polypyrimidine tract binding protein 1).
