About PAXX

Cytogenetic location: 9q34.3 Genomic coordinates (GRCh38): 9:136,992,422-136,993,976 (from NCBI)

This gene has 8 transcripts (splice variants) and 135 orthologues. Ubiquitous expression in spleen (RPKM 25.7), lymph node (RPKM 14.9) and 25 other tissues.

Summary

The protein encoded by this gene plays a role in the nonhomologous end joining (NHEJ) pathway of DNA double-strand break repair. The encoded protein may function to stabilize the Ku70/Ku80 heterodimer to facilitate the assembly and maintain the stability of the NHEJ complex. [provided by RefSeq, Jul 2016]
