Also Known as SNAP190; PTFalpha

Species: Homo sapiens

Gene Type: protein coding

Gene ID: 6621

About SNAPC4

Cytogenetic location: 9q34.3 Genomic coordinates (GRCh38): 9:136,375,571-136,400,170 (from NCBI)

This gene has 7 transcripts (splice variants), 184 orthologues and 6 paralogues. Broad expression in testis (RPKM 5.9), spleen (RPKM 2.6) and 25 other tissues.

Summary

This gene encodes the largest subunit of the small nuclear RNA-activating protein (SNAP) complex. The encoded protein contains a Myb DNA-binding domain, and is essential for RNA polymerase II and III polymerase transcription from small nuclear RNA promoters. A mutation in this gene is associated with ankylosing spondylitis. [provided by RefSeq, Jul 2016]
