The protein encoded by this gene promotes autophagy and is essential for proper autophagosome formation and processing. In addition, the encoded protein can enhance rDNA transcription by helping in the assembly of the POLR1/RNA polymerase I preinitiation complex. Finally, this protein serves as a transcriptional activator for some genes. TP53INP2 (Tumor Protein P53 Inducible Nuclear Protein 2) is a Protein Coding gene. Diseases associated with TP53INP2 include Obesity. Among its related pathways are Autophagy - animal. An important paralog of this gene is TP53INP1.
