SNAPC3 - small nuclear RNA activating complex polypeptide 3 Gene

Also Known as SNAP50; PTFbeta

Species: Homo sapiens

Gene Type: protein coding
Gene ID: 6619

Summary

Predicted to enable RNA polymerase III type 3 promoter sequence-specific DNA binding activity and bent DNA binding activity. Predicted to contribute to RNA polymerase II cis-regulatory region sequence-specific DNA binding activity and core promoter sequence-specific DNA binding activity. Predicted to be involved in snRNA transcription by RNA polymerase II and snRNA transcription by RNA polymerase III. Located in nucleoplasm. [provided by Alliance of Genome Resources, Jun 2026]
Broad expression in testis (RPKM 18.8), brain (RPKM 8.0) and 24 other tissues.
