Novel functions of a retroposed gene

Trends Genet. 2023 Jun;39(6):439-441. doi: 10.1016/j.tig.2023.03.006. Epub 2023 Mar 28.

Abstract

Retroposed protein-coding genes are commonly considered to be nonfunctional duplicates. However, they often gain transcriptional capability and have important roles. Amici et al. recently identified novel functions of a retroposed gene. HAPSTR2, a retrocopy of HAPSTR1, encodes a protein that stabilizes the HAPSTR1 protein and functionally buffers its loss.

Keywords: HAPSTR2; retrocopy.
